Subject [jira] [Commented] (CAMEL-8646) Camel doesn't allow intercept and advice on the same route
Date Thu, 09 Jul 2015 12:54:50 GMT

    [ https://issues.apache.org/jira/browse/CAMEL-8646?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14620453#comment-14620453
] 

Alex Savitsky commented on CAMEL-8646:
--------------------------------------

What do you mean by "latest code"? The latest I see in Maven is 2.15.2, and the code certainly
fails there. Will attach a complete Maven project to illustrate the issue.

> Let's assume we have a route, defined in a RouteBuilder. It allows us to define an interceptor
that would be executed before every route step, via an intercept(Processor) call.
> Routes can also have an advice attached to them, via RouteDefinition.adviceWith(AdviceWithRouteBuilder)
call.
> If these two methods of weaving custom processing into existing routes are combined,
Camel throws an exception:
> {noformat}
> Exception in thread "main" java.lang.IllegalArgumentException: There are no outputs which
matches: * in the route: Route(main)[[From[direct:main]] -> [Intercept[[Log[Intercept ${body}
${headers}]]], Log[Main ${body} ${headers}]]]
> 	at org.apache.camel.builder.AdviceWithTasks$3.task(AdviceWithTasks.java:257)
> 	at org.apache.camel.model.RouteDefinition.adviceWith(RouteDefinition.java:270)
> 	at camel.Test.main(Test.java:20)
> {noformat}
> Simple test to illustrate the issue:
> {noformat}
> import org.apache.camel.builder.AdviceWithRouteBuilder;
> import org.apache.camel.builder.RouteBuilder;
> import org.apache.camel.impl.DefaultCamelContext;
> import org.apache.camel.model.ModelCamelContext;
> public class Test {
> 	public static void main(String[] args) throws Exception {
> 		ModelCamelContext context = new DefaultCamelContext();
> 		RouteBuilder route = new RouteBuilder() {
> 			@Override
> 			public void configure() throws Exception {
> 				from("direct:advice").log("Advice ${body} ${headers}");
> 				from("direct:main").routeId("main").log("Main ${body} ${headers}");
> 			}
> 		};
> 		route.intercept().log("Intercept ${body} ${headers}");
> 		context.addRoutes(route);
> 		context.getRouteDefinition("main").adviceWith(context, new AdviceWithRouteBuilder()
{
> 			@Override
> 			public void configure() throws Exception {
> 				weaveAddFirst().to("direct:advice");
> 			}
> 		});
> 	}
> }
> {noformat}
