Hi All!

I am a noob to AOP. I need to create a setup where I need to detect specific annotation inside classes during EAR deployment. Basically I need to provide a mean for another developer to mark certain methods inside class, and then to be able to find all marked methods deployed on JBoss AS.

I don't know if this is possible with AOP.

For example:

Annotation:

@Target( { ElementType.METHOD })
@Retention(value=RetentionPolicy.RUNTIME)
public @interface MarkMe {
}

Annotated class:

public class TestClass {
    @MarkMe 
    public void testMethod1() {
        System.out.println("Invoked testMethod1");    
    }
}

Now I can create interceptor :

public class TestInterceptor implements Interceptor {
    @Override
    public String getName() {
        return "TestInterceptor";
    }
    @Override
    public Object invoke(Invocation invocation) throws Throwable {
        System.out.println("INSIDE INTERCEPTOR");
        return invocation.invokeNext();
    }
}

to trigger during invocation of the method:

<?xml version="1.0" encoding="UTF-8"?>
<aop xmlns="urn:jboss:aop-beans:1.0">
  <interceptor name="TestInt" class="TestInterceptor"/>   
  <bind pointcut="execution(public void *->@MarkMe())">
    <interceptor-ref name="TestInt"/>
  </bind>
</aop>

However is it possible to detect during deployment of the class that it has been annotated? I thought to use has but it seems that it is only for refinement of the expression.

Could somebody provide me with some hints how to do this?
