bridgeErrorHandler | consumer |
|
| 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. |
exceptionHandler | consumer (advanced) |
| To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this options is not in use. By default the consumer will deal with exceptions that will be logged at WARN/ERROR level and ignored. | |
exchangePattern | consumer (advanced) |
| Sets the exchange pattern when the consumer creates an exchange. | |
synchronous | advanced |
|
| Sets whether synchronous processing should be strictly used or Camel is allowed to use asynchronous processing (if supported). |
login | security |
| The username | |
passcode | security |
| The password | |
sslContextParameters | security |

You can append query options to the URI in the following format,
?option=value&option=value&…
Sending messages:
from("direct:foo").to("stomp:queue:test");Consuming messages:
from("stomp:queue:test").transform(body().convertToString()).to("mock:result")Camel supports the Message Endpoint pattern using the Endpoint interface. Endpoints are usually created by a Component and Endpoints are usually referred to in the DSL via their URIs.
From an Endpoint you can use the following methods
* createProducer() will create a Producer for sending message exchanges to the endpoint * createConsumer() implements the Event Driven Consumer pattern for consuming message exchanges from the endpoint via a Processor when creating a Consumer * createPollingConsumer() implements the Polling Consumer pattern for consuming message exchanges from the endpoint via a PollingConsumer
