Filter Processor

The Filter processor can be used to prevent uninteresting or unwanted messages from reaching the producer endpoint. It will accept a single predicate argument: if the predicate absolves to true, then the message exchange is allowed through to the producer; however if the predicate is false, the message exchange is blocked.

XML DSL:

<camelContext id="filterRoute" xmlns="http://camel.apache.org/schema/spring">
  <route>
    <from uri="SourceURL"/>
    <filter>
      <simple>header.foo = 'bar'</simple>
      <to uri="TargetURL"/>
    </filter>
  </route>
</camelContext>

Java DSL:

from("SourceURL").filter(header("foo").isEqualTo("bar")).to("TargetURL");
