Re: [aspectj-users] how to intercept joinpoints ...

[Paulo Alexandre Corigo Zenida <paulo.zenida@xxxxxxxx>]

Hello,

I believe the following Aspect would to what you wish:

public aspect Aspect2 {

   pointcut pc(): execution(* Foo.m1(..));

   before() : 	adviceexecution() &&
	within(Aspect1) &&
	if(thisJoinPoint.toString().equals("adviceexecution(void 
pt.iscte.ci.example1.Aspect1.before())")) {
	System.out.println("I'm before before m1");
   }

   before() : 	adviceexecution() &&
	within(Aspect1) &&
	if(thisJoinPoint.toString().equals("adviceexecution(void 
pt.iscte.ci.example1.Aspect1.after())")) {
	System.out.println("I'm before after m1");
   }

   after() : 	adviceexecution() &&
	within(Aspect1) &&
	if(thisJoinPoint.toString().equals("adviceexecution(void 
pt.iscte.ci.example1.Aspect1.before())")) {
	System.out.println("I'm after before m1");
   }

   after() : 	adviceexecution() &&
	within(Aspect1) &&
	if(thisJoinPoint.toString().equals("adviceexecution(void 
pt.iscte.ci.example1.Aspect1.after())")) {
	System.out.println("I'm after after m1");
   }
}

The output with this aspect and your code is:

I'm before before m1
I'm before m1
I'm after before m1
I'm on m1
I'm before after m1
I'm after m1
I'm after after m1


Hope this helps.

Best Regards,

Paulo Zenida
