Define routes:

Either using Spring xml or Java DSL.

Spring xml:

<camelContext>

　　<routeBuilder ref="myBuilder" />   //to load the Java DSL routes defined in MyRouteBuilder class

　　<routeContextRef> //to load the routes in <routeContext> defined in other xml file

　   <route> 

　　　　<from> <process> <to>

　　</route>

</....>

<bean id="myBuilder" class="org.apache.camel.spring.example.test1.MyRouteBuilder"/>

Java DSL:

extends RouteBuilder, implement the abstract method configure().

@Override
public void configure() throws Exception {

　　Endpoint orderUpdates = endpoint("pubsub://batman-order-updates");
　　from("pubsub://adv-updates").process(galaxyAdvCache.input(header(Ref.INBOX)));

}
