7.2. Event Message
Event Message
Camel supports the Event Message from the Introducing Enterprise Integration Patterns by supporting the Exchange Pattern on a Message which can be set to InOnly to indicate a oneway event message. Camel Components then implement this pattern using the underlying transport or protocols.
Explicitly specifying InOnly
If you are using a component which defaults to InOut you can override the Message Exchange Pattern for an endpoint using the pattern property.
foo:bar?exchangePattern=InOnly
From 2.0 onwards on Camel you can specify the Message Exchange Pattern using the dsl.
Using the Fluent Builders
from("mq:someQueue").
inOnly().
bean(Foo.class);
or you can invoke an endpoint with an explicit pattern
from("mq:someQueue").
inOnly("mq:anotherQueue");
Using the Spring XML Extensions
<route>
<from uri="mq:someQueue"/>
<inOnly uri="bean:foo"/>
</route><route>
<from uri="mq:someQueue"/>
<inOnly uri="mq:anotherQueue"/>
</route>
