The amqp: component supports the AMQP 1.0 protocol using the JMS Client API of the Qpid project. In case you want to use AMQP 0.9 (in particular RabbitMQ) you might also be interested in the Camel RabbitMQ component. Please keep in mind that prior to the Camel 2.17.0 AMQP component supported AMQP 0.9 and above, however since Camel 2.17.0 it supports only AMQP 1.0.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-amqp</artifactId>
    <version>${camel.version}</version> <!-- use the same version as your Camel core version -->
</dependency>

AMQP Options

You can specify all of the various configuration options of the JMS component after the destination name.

The AMQP component supports 74 options which are listed below.

{% raw %}

NameJava TypeDescription

configuration

JmsConfiguration

To use a shared JMS configuration

acceptMessagesWhileStopping

boolean

Specifies whether the consumer accept messages while it is stopping. You may consider enabling this option if you start and stop JMS routes at runtime while there are still messages enqued on the queue. If this option is false and you stop the JMS route then messages may be rejected and the JMS broker would have to attempt redeliveries which yet again may be rejected and eventually the message may be moved at a dead letter queue on the JMS broker. To avoid this its recommended to enable this option.

allowReplyManagerQuickStop

boolean

Whether the DefaultMessageListenerContainer used in the reply managers for request-reply messaging allow the DefaultMessageListenerContainer.runningAllowed flag to quick stop in case JmsConfigurationisAcceptMessagesWhileStopping is enabled and org.apache.camel.CamelContext is currently being stopped. This quick stop ability is enabled by default in the regular JMS consumers but to enable for reply managers you must enable this flag.

acknowledgementMode

int

The JMS acknowledgement mode defined as an Integer. Allows you to set vendor-specific extensions to the acknowledgment mode. For the regular modes it is preferable to use the acknowledgementModeName instead.

eagerLoadingOfProperties

boolean

Enables eager loading of JMS properties as soon as a message is loaded which generally is inefficient as the JMS properties may not be required but sometimes can catch early any issues with the underlying JMS provider and the use of JMS properties

acknowledgementModeName

String

The JMS acknowledgement name which is one of: SESSION_TRANSACTED CLIENT_ACKNOWLEDGE AUTO_ACKNOWLEDGE DUPS_OK_ACKNOWLEDGE

autoStartup

boolean

Specifies whether the consumer container should auto-startup.

cacheLevel

int

Sets the cache level by ID for the underlying JMS resources. See cacheLevelName option for more details.

cacheLevelName

String

Sets the cache level by name for the underlying JMS resources. Possible values are: CACHE_AUTO CACHE_CONNECTION CACHE_CONSUMER CACHE_NONE and CACHE_SESSION. The default setting is CACHE_AUTO. See the Spring documentation and Transactions Cache Levels for more information.

replyToCacheLevelName

String

Sets the cache level by name for the reply consumer when doing request/reply over JMS. This option only applies when using fixed reply queues (not temporary). Camel will by default use: CACHE_CONSUMER for exclusive or shared w/ replyToSelectorName. And CACHE_SESSION for shared without replyToSelectorName. Some JMS brokers such as IBM WebSphere may require to set the replyToCacheLevelName=CACHE_NONE to work. Note: If using temporary queues then CACHE_NONE is not allowed and you must use a higher value such as CACHE_CONSUMER or CACHE_SESSION.

clientId

String

Sets the JMS client ID to use. Note that this value if specified must be unique and can only be used by a single JMS connection instance. It is typically only required for durable topic subscriptions. If using Apache ActiveMQ you may prefer to use Virtual Topics instead.

concurrentConsumers

int

Specifies the default number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToConcurrentConsumers is used to control number of concurrent consumers on the reply message listener.

replyToConcurrentConsumers

int

Specifies the default number of concurrent consumers when doing request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.

connectionFactory

ConnectionFactory

Sets the default connection factory to be use

username

String

Username to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.

password

String

Password to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.

deliveryPersistent

boolean

Specifies whether persistent delivery is used by default.

deliveryMode

Integer

Specifies the delivery mode to be used. Possible values are Possibles values are those defined by javax.jms.DeliveryMode. NON_PERSISTENT = 1 and PERSISTENT = 2.

durableSubscriptionName

String

The durable subscriber name for specifying durable topic subscriptions. The clientId option must be configured as well.

exceptionListener

ExceptionListener

Specifies the JMS Exception Listener that is to be notified of any underlying JMS exceptions.

errorHandler

ErrorHandler

Specifies a org.springframework.util.ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message. By default these exceptions will be logged at the WARN level if no errorHandler has been configured. You can configure logging level and whether stack traces should be logged using errorHandlerLoggingLevel and errorHandlerLogStackTrace options. This makes it much easier to configure than having to code a custom errorHandler.

errorHandlerLoggingLevel

LoggingLevel

Allows to configure the default errorHandler logging level for logging uncaught exceptions.

errorHandlerLogStackTrace

boolean

Allows to control whether stacktraces should be logged or not by the default errorHandler.

explicitQosEnabled

boolean

Set if the deliveryMode priority or timeToLive qualities of service should be used when sending messages. This option is based on Spring’s JmsTemplate. The deliveryMode priority and timeToLive options are applied to the current endpoint. This contrasts with the preserveMessageQos option which operates at message granularity reading QoS properties exclusively from the Camel In message headers.

exposeListenerSession

boolean

Specifies whether the listener session should be exposed when consuming messages.

idleTaskExecutionLimit

int

Specifies the limit for idle executions of a receive task not having received any message within its execution. If this limit is reached the task will shut down and leave receiving to other executing tasks (in the case of dynamic scheduling; see the maxConcurrentConsumers setting). There is additional doc available from Spring.

idleConsumerLimit

int

Specify the limit for the number of consumers that are allowed to be idle at any given time.

maxConcurrentConsumers

int

Specifies the maximum number of concurrent consumers when consuming from JMS (not for request/reply over JMS). See also the maxMessagesPerTask option to control dynamic scaling up/down of threads. When doing request/reply over JMS then the option replyToMaxConcurrentConsumers is used to control number of concurrent consumers on the reply message listener.

replyToMaxConcurrentConsumers

int

Specifies the maximum number of concurrent consumers when using request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.

replyOnTimeoutToMaxConcurrentConsumers

int

Specifies the maximum number of concurrent consumers for continue routing when timeout occurred when using request/reply over JMS.

maxMessagesPerTask

int

The number of messages per task. -1 is unlimited. If you use a range for concurrent consumers (eg min max) then this option can be used to set a value to eg 100 to control how fast the consumers will shrink when less work is required.

messageConverter

MessageConverter

To use a custom Spring org.springframework.jms.support.converter.MessageConverter so you can be in control how to map to/from a javax.jms.Message.

mapJmsMessage

boolean

Specifies whether Camel should auto map the received JMS message to a suited payload type such as javax.jms.TextMessage to a String etc. See section about how mapping works below for more details.

messageIdEnabled

boolean

When sending specifies whether message IDs should be added.

messageTimestampEnabled

boolean

Specifies whether timestamps should be enabled by default on sending messages.

alwaysCopyMessage

boolean

If true Camel will always make a JMS message copy of the message when it is passed to the producer for sending. Copying the message is needed in some situations such as when a replyToDestinationSelectorName is set (incidentally Camel will set the alwaysCopyMessage option to true if a replyToDestinationSelectorName is set)

useMessageIDAsCorrelationID

boolean

Specifies whether JMSMessageID should always be used as JMSCorrelationID for InOut messages.

priority

int

Values greater than 1 specify the message priority when sending (where 0 is the lowest priority and 9 is the highest). The explicitQosEnabled option must also be enabled in order for this option to have any effect.

pubSubNoLocal

boolean

Specifies whether to inhibit the delivery of messages published by its own connection.

receiveTimeout

long

The timeout for receiving messages (in milliseconds).

recoveryInterval

long

Specifies the interval between recovery attempts i.e. when a connection is being refreshed in milliseconds. The default is 5000 ms that is 5 seconds.

subscriptionDurable

boolean

Deprecated: Enabled by default if you specify a durableSubscriptionName and a clientId.

taskExecutor

TaskExecutor

Allows you to specify a custom task executor for consuming messages.

timeToLive

long

When sending messages specifies the time-to-live of the message (in milliseconds).

transacted

boolean

Specifies whether to use transacted mode

lazyCreateTransactionManager

boolean

If true Camel will create a JmsTransactionManager if there is no transactionManager injected when option transacted=true.

transactionManager

PlatformTransactionManager

The Spring transaction manager to use.

transactionName

String

The name of the transaction to use.

transactionTimeout

int

The timeout value of the transaction (in seconds) if using transacted mode.

testConnectionOnStartup

boolean

Specifies whether to test the connection on startup. This ensures that when Camel starts that all the JMS consumers have a valid connection to the JMS broker. If a connection cannot be granted then Camel throws an exception on startup. This ensures that Camel is not started with failed connections. The JMS producers is tested as well.

asyncStartListener

boolean

Whether to startup the JmsConsumer message listener asynchronously when starting a route. For example if a JmsConsumer cannot get a connection to a remote JMS broker then it may block while retrying and/or failover. This will cause Camel to block while starting routes. By setting this option to true you will let routes startup while the JmsConsumer connects to the JMS broker using a dedicated thread in asynchronous mode. If this option is used then beware that if the connection could not be established then an exception is logged at WARN level and the consumer will not be able to receive messages; You can then restart the route to retry.

asyncStopListener

boolean

Whether to stop the JmsConsumer message listener asynchronously when stopping a route.

forceSendOriginalMessage

boolean

When using mapJmsMessage=false Camel will create a new JMS message to send to a new JMS destination if you touch the headers (get or set) during the route. Set this option to true to force Camel to send the original JMS message that was received.

requestTimeout

long

The timeout for waiting for a reply when using the InOut Exchange Pattern (in milliseconds). The default is 20 seconds. You can include the header CamelJmsRequestTimeout to override this endpoint configured timeout value and thus have per message individual timeout values. See also the requestTimeoutCheckerInterval option.

requestTimeoutCheckerInterval

long

Configures how often Camel should check for timed out Exchanges when doing request/reply over JMS. By default Camel checks once per second. But if you must react faster when a timeout occurs then you can lower this interval to check more frequently. The timeout is determined by the option requestTimeout.

transferExchange

boolean

You can transfer the exchange over the wire instead of just the body and headers. The following fields are transferred: In body Out body Fault body In headers Out headers Fault headers exchange properties exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. You must enable this option on both the producer and consumer side so Camel knows the payloads is an Exchange and not a regular payload.

transferException

boolean

If enabled and you are using Request Reply messaging (InOut) and an Exchange failed on the consumer side then the caused Exception will be send back in response as a javax.jms.ObjectMessage. If the client is Camel the returned Exception is rethrown. This allows you to use Camel JMS as a bridge in your routing - for example using persistent queues to enable robust routing. Notice that if you also have transferExchange enabled this option takes precedence. The caught exception is required to be serializable. The original Exception on the consumer side can be wrapped in an outer exception such as org.apache.camel.RuntimeCamelException when returned to the producer.

transferFault

boolean

If enabled and you are using Request Reply messaging (InOut) and an Exchange failed with a SOAP fault (not exception) on the consumer side then the fault flag on link org.apache.camel.MessageisFault() will be send back in the response as a JMS header with the key link JmsConstantsJMS_TRANSFER_FAULT. If the client is Camel the returned fault flag will be set on the link org.apache.camel.MessagesetFault(boolean). You may want to enable this when using Camel components that support faults such as SOAP based such as cxf or spring-ws.

jmsOperations

JmsOperations

Allows you to use your own implementation of the org.springframework.jms.core.JmsOperations interface. Camel uses JmsTemplate as default. Can be used for testing purpose but not used much as stated in the spring API docs.

destinationResolver

DestinationResolver

A pluggable org.springframework.jms.support.destination.DestinationResolver that allows you to use your own resolver (for example to lookup the real destination in a JNDI registry).

replyToType

ReplyToType

Allows for explicitly specifying which kind of strategy to use for replyTo queues when doing request/reply over JMS. Possible values are: Temporary Shared or Exclusive. By default Camel will use temporary queues. However if replyTo has been configured then Shared is used by default. This option allows you to use exclusive queues instead of shared ones. See Camel JMS documentation for more details and especially the notes about the implications if running in a clustered environment and the fact that Shared reply queues has lower performance than its alternatives Temporary and Exclusive.

preserveMessageQos

boolean

Set to true if you want to send message using the QoS settings specified on the message instead of the QoS settings on the JMS endpoint. The following three headers are considered JMSPriority JMSDeliveryMode and JMSExpiration. You can provide all or only some of them. If not provided Camel will fall back to use the values from the endpoint instead. So when using this option the headers override the values from the endpoint. The explicitQosEnabled option by contrast will only use options set on the endpoint and not values from the message header.

asyncConsumer

boolean

Whether the JmsConsumer processes the Exchange asynchronously. If enabled then the JmsConsumer may pickup the next message from the JMS queue while the previous message is being processed asynchronously (by the Asynchronous Routing Engine). This means that messages may be processed not 100 strictly in order. If disabled (as default) then the Exchange is fully processed before the JmsConsumer will pickup the next message from the JMS queue. Note if transacted has been enabled then asyncConsumer=true does not run asynchronously as transaction must be executed synchronously (Camel 3.0 may support async transactions).

allowNullBody

boolean

Whether to allow sending messages with no body. If this option is false and the message body is null then an JMSException is thrown.

includeSentJMSMessageID

boolean

Only applicable when sending to JMS destination using InOnly (eg fire and forget). Enabling this option will enrich the Camel Exchange with the actual JMSMessageID that was used by the JMS client when the message was sent to the JMS destination.

includeAllJMSXProperties

boolean

Whether to include all JMSXxxx properties when mapping from JMS to Camel Message. Setting this to true will include properties such as JMSXAppID and JMSXUserID etc. Note: If you are using a custom headerFilterStrategy then this option does not apply.

defaultTaskExecutorType

DefaultTaskExecutorType

Specifies what default TaskExecutor type to use in the DefaultMessageListenerContainer for both consumer endpoints and the ReplyTo consumer of producer endpoints. Possible values: SimpleAsync (uses Spring’s SimpleAsyncTaskExecutor) or ThreadPool (uses Spring’s ThreadPoolTaskExecutor with optimal values - cached threadpool-like). If not set it defaults to the previous behaviour which uses a cached thread pool for consumer endpoints and SimpleAsync for reply consumers. The use of ThreadPool is recommended to reduce thread trash in elastic configurations with dynamically increasing and decreasing concurrent consumers.

jmsKeyFormatStrategy

JmsKeyFormatStrategy

Pluggable strategy for encoding and decoding JMS keys so they can be compliant with the JMS specification. Camel provides two implementations out of the box: default and passthrough. The default strategy will safely marshal dots and hyphens (. and -). The passthrough strategy leaves the key as is. Can be used for JMS brokers which do not care whether JMS header keys contain illegal characters. You can provide your own implementation of the org.apache.camel.component.jms.JmsKeyFormatStrategy and refer to it using the notation.

applicationContext

ApplicationContext

Sets the Spring ApplicationContext to use

queueBrowseStrategy

QueueBrowseStrategy

To use a custom QueueBrowseStrategy when browsing queues

headerFilterStrategy

HeaderFilterStrategy

To use a custom HeaderFilterStrategy to filter header to and from Camel message.

messageCreatedStrategy

MessageCreatedStrategy

To use the given MessageCreatedStrategy which are invoked when Camel creates new instances of javax.jms.Message objects when Camel is sending a JMS message.

waitForProvisionCorrelationToBeUpdatedCounter

int

Number of times to wait for provisional correlation id to be updated to the actual correlation id when doing request/reply over JMS and when the option useMessageIDAsCorrelationID is enabled.

waitForProvisionCorrelationToBeUpdatedThreadSleepingTime

long

Interval in millis to sleep each time while waiting for provisional correlation id to be updated.

false

boolean

If true a producer will behave like a InOnly exchange with the exception that JMSReplyTo header is sent out and not be suppressed like in the case of InOnly. Like InOnly the producer will not wait for a reply. A consumer with this flag will behave like InOnly. This feature can be used to bridge InOut requests to another queue so that a route on the other queue will send its response directly back to the original JMSReplyTo.

boolean

Allows for bridging the consumer to the Camel routing Error Handler which mean any exceptions occurred while the consumer is trying to pickup incoming messages or the likes will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions that will be logged at WARN/ERROR level and ignored.

cacheLevelName

consumer

CACHE_AUTO

String

Sets the cache level by name for the underlying JMS resources. Possible values are: CACHE_AUTO CACHE_CONNECTION CACHE_CONSUMER CACHE_NONE and CACHE_SESSION. The default setting is CACHE_AUTO. See the Spring documentation and Transactions Cache Levels for more information.

acceptMessagesWhileStopping

consumer (advanced)

false

boolean

Specifies whether the consumer accept messages while it is stopping. You may consider enabling this option if you start and stop JMS routes at runtime while there are still messages enqued on the queue. If this option is false and you stop the JMS route then messages may be rejected and the JMS broker would have to attempt redeliveries which yet again may be rejected and eventually the message may be moved at a dead letter queue on the JMS broker. To avoid this its recommended to enable this option.

allowReplyManagerQuickStop

false

boolean

Whether the DefaultMessageListenerContainer used in the reply managers for request-reply messaging allow the DefaultMessageListenerContainer.runningAllowed flag to quick stop in case JmsConfigurationisAcceptMessagesWhileStopping is enabled and org.apache.camel.CamelContext is currently being stopped. This quick stop ability is enabled by default in the regular JMS consumers but to enable for reply managers you must enable this flag.

consumerType

consumer (advanced)

Default

ConsumerType

The consumer type to use which can be one of: Simple Default or Custom. The consumer type determines which Spring JMS listener to use. Default will use org.springframework.jms.listener.DefaultMessageListenerContainer Simple will use org.springframework.jms.listener.SimpleMessageListenerContainer. When Custom is specified the MessageListenerContainerFactory defined by the messageListenerContainerFactory option will determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use.

ExchangePattern

Sets the exchange pattern when the consumer creates an exchange.

exposeListenerSession

consumer (advanced)

false

boolean

Specifies whether the listener session should be exposed when consuming messages.

replyToSameDestinationAllowed

consumer (advanced)

false

boolean

Whether a JMS consumer is allowed to send a reply message to the same destination that the consumer is using to consume from. This prevents an endless loop by consuming and sending back the same message to itself.

deliveryMode

producer

 

Integer

Specifies the delivery mode to be used. Possibles values are those defined by javax.jms.DeliveryMode. NON_PERSISTENT = 1 and PERSISTENT = 2.

deliveryPersistent

producer

true

boolean

Specifies whether persistent delivery is used by default.

explicitQosEnabled

producer

false

Boolean

Set if the deliveryMode priority or timeToLive qualities of service should be used when sending messages. This option is based on Spring’s JmsTemplate. The deliveryMode priority and timeToLive options are applied to the current endpoint. This contrasts with the preserveMessageQos option which operates at message granularity reading QoS properties exclusively from the Camel In message headers.

preserveMessageQos

producer

false

boolean

Set to true if you want to send message using the QoS settings specified on the message instead of the QoS settings on the JMS endpoint. The following three headers are considered JMSPriority JMSDeliveryMode and JMSExpiration. You can provide all or only some of them. If not provided Camel will fall back to use the values from the endpoint instead. So when using this option the headers override the values from the endpoint. The explicitQosEnabled option by contrast will only use options set on the endpoint and not values from the message header.

priority

producer

4

int

Values greater than 1 specify the message priority when sending (where 0 is the lowest priority and 9 is the highest). The explicitQosEnabled option must also be enabled in order for this option to have any effect.

replyToConcurrentConsumers

producer

1

int

Specifies the default number of concurrent consumers when doing request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.

replyToMaxConcurrentConsumers

producer

 

int

Specifies the maximum number of concurrent consumers when using request/reply over JMS. See also the maxMessagesPerTask option to control dynamic scaling up/down of threads.

replyToOnTimeoutMaxConcurrentConsumers

producer

1

int

Specifies the maximum number of concurrent consumers for continue routing when timeout occurred when using request/reply over JMS.

replyToOverride

producer

 

String

Provides an explicit ReplyTo destination in the JMS message which overrides the setting of replyTo. It is useful if you want to forward the message to a remote Queue and receive the reply message from the ReplyTo destination.

replyToType

producer

 

ReplyToType

Allows for explicitly specifying which kind of strategy to use for replyTo queues when doing request/reply over JMS. Possible values are: Temporary Shared or Exclusive. By default Camel will use temporary queues. However if replyTo has been configured then Shared is used by default. This option allows you to use exclusive queues instead of shared ones. See Camel JMS documentation for more details and especially the notes about the implications if running in a clustered environment and the fact that Shared reply queues has lower performance than its alternatives Temporary and Exclusive.

requestTimeout

producer

20000

long

The timeout for waiting for a reply when using the InOut Exchange Pattern (in milliseconds). The default is 20 seconds. You can include the header CamelJmsRequestTimeout to override this endpoint configured timeout value and thus have per message individual timeout values. See also the requestTimeoutCheckerInterval option.

timeToLive

producer

-1

long

When sending messages specifies the time-to-live of the message (in milliseconds).

allowNullBody

producer (advanced)

true

boolean

Whether to allow sending messages with no body. If this option is false and the message body is null then an JMSException is thrown.

alwaysCopyMessage

producer (advanced)

false

boolean

If true Camel will always make a JMS message copy of the message when it is passed to the producer for sending. Copying the message is needed in some situations such as when a replyToDestinationSelectorName is set (incidentally Camel will set the alwaysCopyMessage option to true if a replyToDestinationSelectorName is set)

disableTimeToLive

producer (advanced)

false

boolean

Use this option to force disabling time to live. For example when you do request/reply over JMS then Camel will by default use the requestTimeout value as time to live on the message being sent. The problem is that the sender and receiver systems have to have their clocks synchronized so they are in sync. This is not always so easy to archive. So you can use disableTimeToLive=true to not set a time to live value on the sent message. Then the message will not expire on the receiver system. See below in section About time to live for more details.

forceSendOriginalMessage

producer (advanced)

false

boolean

When using mapJmsMessage=false Camel will create a new JMS message to send to a new JMS destination if you touch the headers (get or set) during the route. Set this option to true to force Camel to send the original JMS message that was received.

includeSentJMSMessageID

producer (advanced)

false

boolean

Only applicable when sending to JMS destination using InOnly (eg fire and forget). Enabling this option will enrich the Camel Exchange with the actual JMSMessageID that was used by the JMS client when the message was sent to the JMS destination.

replyToCacheLevelName

producer (advanced)

 

String

Sets the cache level by name for the reply consumer when doing request/reply over JMS. This option only applies when using fixed reply queues (not temporary). Camel will by default use: CACHE_CONSUMER for exclusive or shared w/ replyToSelectorName. And CACHE_SESSION for shared without replyToSelectorName. Some JMS brokers such as IBM WebSphere may require to set the replyToCacheLevelName=CACHE_NONE to work. Note: If using temporary queues then CACHE_NONE is not allowed and you must use a higher value such as CACHE_CONSUMER or CACHE_SESSION.

replyToDestinationSelectorName

producer (advanced)

 

String

Sets the JMS Selector using the fixed name to be used so you can filter out your own replies from the others when using a shared queue (that is if you are not using a temporary reply queue).

asyncStartListener

advanced

false

boolean

Whether to startup the JmsConsumer message listener asynchronously when starting a route. For example if a JmsConsumer cannot get a connection to a remote JMS broker then it may block while retrying and/or failover. This will cause Camel to block while starting routes. By setting this option to true you will let routes startup while the JmsConsumer connects to the JMS broker using a dedicated thread in asynchronous mode. If this option is used then beware that if the connection could not be established then an exception is logged at WARN level and the consumer will not be able to receive messages; You can then restart the route to retry.

asyncStopListener

advanced

false

boolean

Whether to stop the JmsConsumer message listener asynchronously when stopping a route.

destinationResolver

advanced

 

DestinationResolver

A pluggable org.springframework.jms.support.destination.DestinationResolver that allows you to use your own resolver (for example to lookup the real destination in a JNDI registry).

errorHandler

advanced

 

ErrorHandler

Specifies a org.springframework.util.ErrorHandler to be invoked in case of any uncaught exceptions thrown while processing a Message. By default these exceptions will be logged at the WARN level if no errorHandler has been configured. You can configure logging level and whether stack traces should be logged using errorHandlerLoggingLevel and errorHandlerLogStackTrace options. This makes it much easier to configure than having to code a custom errorHandler.

errorHandlerLoggingLevel

advanced

WARN

LoggingLevel

Allows to configure the default errorHandler logging level for logging uncaught exceptions.

errorHandlerLogStackTrace

advanced

true

boolean

Allows to control whether stacktraces should be logged or not by the default errorHandler.

exceptionListener

advanced

 

ExceptionListener

Specifies the JMS Exception Listener that is to be notified of any underlying JMS exceptions.

headerFilterStrategy

advanced

 

HeaderFilterStrategy

To use a custom HeaderFilterStrategy to filter header to and from Camel message.

idleConsumerLimit

advanced

1

int

Specify the limit for the number of consumers that are allowed to be idle at any given time.

idleTaskExecutionLimit

advanced

1

int

Specifies the limit for idle executions of a receive task not having received any message within its execution. If this limit is reached the task will shut down and leave receiving to other executing tasks (in the case of dynamic scheduling; see the maxConcurrentConsumers setting). There is additional doc available from Spring.

includeAllJMSXProperties

advanced

false

boolean

Whether to include all JMSXxxx properties when mapping from JMS to Camel Message. Setting this to true will include properties such as JMSXAppID and JMSXUserID etc. Note: If you are using a custom headerFilterStrategy then this option does not apply.

jmsKeyFormatStrategy

advanced

 

String

Pluggable strategy for encoding and decoding JMS keys so they can be compliant with the JMS specification. Camel provides two implementations out of the box: default and passthrough. The default strategy will safely marshal dots and hyphens (. and -). The passthrough strategy leaves the key as is. Can be used for JMS brokers which do not care whether JMS header keys contain illegal characters. You can provide your own implementation of the org.apache.camel.component.jms.JmsKeyFormatStrategy and refer to it using the notation.

mapJmsMessage

advanced

true

boolean

Specifies whether Camel should auto map the received JMS message to a suited payload type such as javax.jms.TextMessage to a String etc.

maxMessagesPerTask

advanced

-1

int

The number of messages per task. -1 is unlimited. If you use a range for concurrent consumers (eg min max) then this option can be used to set a value to eg 100 to control how fast the consumers will shrink when less work is required.

messageConverter

advanced

 

MessageConverter

To use a custom Spring org.springframework.jms.support.converter.MessageConverter so you can be in control how to map to/from a javax.jms.Message.

messageCreatedStrategy

advanced

 

MessageCreatedStrategy

To use the given MessageCreatedStrategy which are invoked when Camel creates new instances of javax.jms.Message objects when Camel is sending a JMS message.

messageIdEnabled

advanced

true

boolean

When sending specifies whether message IDs should be added. This is just an hint to the JMS broker.If the JMS provider accepts this hint these messages must have the message ID set to null; if the provider ignores the hint the message ID must be set to its normal unique value

messageListenerContainerFactory

advanced

 

MessageListenerContainerFactory

Registry ID of the MessageListenerContainerFactory used to determine what org.springframework.jms.listener.AbstractMessageListenerContainer to use to consume messages. Setting this will automatically set consumerType to Custom.

messageTimestampEnabled

advanced

true

boolean

Specifies whether timestamps should be enabled by default on sending messages. This is just an hint to the JMS broker.If the JMS provider accepts this hint these messages must have the timestamp set to zero; if the provider ignores the hint the timestamp must be set to its normal value

pubSubNoLocal

advanced

false

boolean

Specifies whether to inhibit the delivery of messages published by its own connection.

receiveTimeout

advanced

1000

long

The timeout for receiving messages (in milliseconds).

recoveryInterval

advanced

5000

long

Specifies the interval between recovery attempts i.e. when a connection is being refreshed in milliseconds. The default is 5000 ms that is 5 seconds.

requestTimeoutCheckerInterval

advanced

1000

long

Configures how often Camel should check for timed out Exchanges when doing request/reply over JMS. By default Camel checks once per second. But if you must react faster when a timeout occurs then you can lower this interval to check more frequently. The timeout is determined by the option requestTimeout.

synchronous

advanced

false

boolean

Sets whether synchronous processing should be strictly used or Camel is allowed to use asynchronous processing (if supported).

transferException

advanced

false

boolean

If enabled and you are using Request Reply messaging (InOut) and an Exchange failed on the consumer side then the caused Exception will be send back in response as a javax.jms.ObjectMessage. If the client is Camel the returned Exception is rethrown. This allows you to use Camel JMS as a bridge in your routing - for example using persistent queues to enable robust routing. Notice that if you also have transferExchange enabled this option takes precedence. The caught exception is required to be serializable. The original Exception on the consumer side can be wrapped in an outer exception such as org.apache.camel.RuntimeCamelException when returned to the producer.

transferExchange

advanced

false

boolean

You can transfer the exchange over the wire instead of just the body and headers. The following fields are transferred: In body Out body Fault body In headers Out headers Fault headers exchange properties exchange exception. This requires that the objects are serializable. Camel will exclude any non-serializable objects and log it at WARN level. You must enable this option on both the producer and consumer side so Camel knows the payloads is an Exchange and not a regular payload.

transferFault

advanced

false

boolean

If enabled and you are using Request Reply messaging (InOut) and an Exchange failed with a SOAP fault (not exception) on the consumer side then the fault flag on MessageisFault() will be send back in the response as a JMS header with the key org.apache.camel.component.jms.JmsConstantsJMS_TRANSFER_FAULTJMS_TRANSFER_FAULT. If the client is Camel the returned fault flag will be set on the link org.apache.camel.MessagesetFault(boolean). You may want to enable this when using Camel components that support faults such as SOAP based such as cxf or spring-ws.

useMessageIDAsCorrelationID

advanced

false

boolean

Specifies whether JMSMessageID should always be used as JMSCorrelationID for InOut messages.

waitForProvisionCorrelationToBeUpdatedCounter

advanced

50

int

Number of times to wait for provisional correlation id to be updated to the actual correlation id when doing request/reply over JMS and when the option useMessageIDAsCorrelationID is enabled.

waitForProvisionCorrelationToBeUpdatedThreadSleepingTime

advanced

100

long

Interval in millis to sleep each time while waiting for provisional correlation id to be updated.

password

security

 

String

Password to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.

username

security

 

String

Username to use with the ConnectionFactory. You can also configure username/password directly on the ConnectionFactory.

transacted

transaction

false

boolean

Specifies whether to use transacted mode

lazyCreateTransactionManager

transaction (advanced)

true

boolean

If true Camel will create a JmsTransactionManager if there is no transactionManager injected when option transacted=true.

transactionManager

transaction (advanced)

 

PlatformTransactionManager

The Spring transaction manager to use.

transactionName

transaction (advanced)

 

String

The name of the transaction to use.

transactionTimeout

transaction (advanced)

-1

int

The timeout value of the transaction (in seconds) if using transacted mode.

Usage

As AMQP component is inherited from JMS component, the usage of the former is almost identical to the latter:

Using AMQP component

// Consuming from AMQP queue
from("amqp:queue:incoming").
  to(...);
 
// Sending message to the AMQP topic
from(...).
  to("amqp:topic:notify");

Configuring AMQP component

Starting from the Camel 2.16.1 you can also use the AMQPComponent#amqp10Component(String connectionURI) factory method to return the AMQP 1.0 component with the pre-configured topic prefix: 

Creating AMQP 1.0 component

 AMQPComponent amqp = AMQPComponent.amqp10Component("amqp://guest:guest@localhost:5672");

Keep in mind that starting from the Camel 2.17 the AMQPComponent#amqp10Component(String connectionURI) factory method has been deprecated on the behalf of the AMQPComponent#amqpComponent(String connectionURI)

Creating AMQP 1.0 component

AMQPComponent amqp = AMQPComponent.amqpComponent("amqp://localhost:5672");
 
AMQPComponent authorizedAmqp = AMQPComponent.amqpComponent("amqp://localhost:5672", "user", "password");

Starting from Camel 2.17, in order to automatically configure the AMQP component, you can also add an instance of org.apache.camel.component.amqp.AMQPConnectionDetails to the registry. For example for Spring Boot you just have to define bean:

AMQP connection details auto-configuration

@Bean
AMQPConnectionDetails amqpConnection() {
  return new AMQPConnectionDetails("amqp://localhost:5672");
}
 
@Bean
AMQPConnectionDetails securedAmqpConnection() {
  return new AMQPConnectionDetails("amqp://lcoalhost:5672", "username", "password");
}

Likewise, you can also use CDI producer methods when using Camel-CDI

AMQP connection details auto-configuration for CDI

@Produces
AMQPConnectionDetails amqpConnection() {
  return new AMQPConnectionDetails("amqp://localhost:5672");
}

You can also rely on the Camel properties to read the AMQP connection details. Factory method AMQPConnectionDetails.discoverAMQP() attempts to read Camel properties in a Kubernetes-like convention, just as demonstrated on the snippet below:

 

AMQP connection details auto-configuration

export AMQP_SERVICE_HOST = "mybroker.com"
export AMQP_SERVICE_PORT = "6666"
export AMQP_SERVICE_USERNAME = "username"
export AMQP_SERVICE_PASSWORD = "password"
 
...
 
@Bean
AMQPConnectionDetails amqpConnection() {
  return AMQPConnectionDetails.discoverAMQP();
}

Using topics

To have using topics working with camel-amqp you need to configure the component to use topic:// as topic prefix, as shown below:

 <bean id="amqp" class="org.apache.camel.component.amqp.AmqpComponent">
        <property name="connectionFactory">
          <bean class="org.apache.qpid.amqp_1_0.jms.impl.ConnectionFactoryImpl" factory-method="createFromURL">
            <constructor-arg index="0" type="java.lang.String" value="amqp://localhost:5672" />
            <property name="topicPrefix" value="topic://" />  <!-- only necessary when connecting to ActiveMQ over AMQP 1.0 -->
          </bean>
        </property>
 </bean>

Keep in mind that both  AMQPComponent#amqpComponent() methods and AMQPConnectionDetails pre-configure the component with the topic prefix, so you don’t have to configure it explicitly.
