Content Based Router

The Content Based Router from the EIP patterns allows you to route messages to the correct destination based on the contents of the message exchanges.

The following example shows how to route a request from an input queue:a endpoint to either queue:b, queue:c or queue:d depending on the evaluation of various Predicate expressions

Using the Fluent Builders

RouteBuilder builder = new RouteBuilder() {
    public void configure() {

Using the Spring XML Extensions

<camelContext id="camel" xmlns="http://activemq.apache.org/camel/schema/spring">
    <from uri="seda:a"/>
        <xpath>$foo = 'bar'</xpath>
        <to uri="seda:b"/>
        <xpath>$foo = 'cheese'</xpath>
        <to uri="seda:c"/>
        <to uri="seda:d"/>

For further examples of this pattern in use you could look at the junit test case

Using This Pattern

If you would like to use this EIP Pattern then please read the Getting Started, you may also find the Architecture useful particularly the description of Endpoint and URIs. Then you could try out some of the Examples first before trying this pattern out.
