[aspectj-users] Trace method calls with around advice

[Martin Burger <mburger@xxxxxxxxxxxx>]

Hello!

I want to trace method calls using an around advice. It is important 
that I can associate method calls and their return value and a thrown 
exception, respectively. So, using before and after advices does not 
meet my requirements (without using the stack information).

An advice like the following could do the job:


   Object around() throws Exception: aCall() {
       
       logger.trace("Before proceed: " + thisJoinPoint);
       
       int id = Manager.record(thisJoinPoint);

       Object returned = null;
       
       try {
           returned = proceed();
       } catch (Exception e) {
           logger.trace("After proceed: " + thisJoinPoint);
           logger.trace("Threw an exception: " + e);
           Manager.recordException(id, e);
           throw e;
       }

       logger.trace("After proceed: " + thisJoinPoint);
       logger.trace("Returned normally with " + returned);

       Manager.record(id, returned);
     
       return returned;
   }


Unfortunately, that advice does not work. Using an RuntimeException will 
not handle method with checked exceptions.

Is there any way to do this job using AspectJ?
