[aspectj-users] general tracing aspect

[Nuno Oliveira <noliveira@xxxxxx>]

Hello all,

I have a bunch of classes each with its own static instance of a log4j
logger. This instances all have the same name 'logger'. I want to add
enter-leave tracing to each of the methods of all classes but would be
interested in making this with a single aspect. However I'm having trouble
with the sintax to refer to the logger in my advice, without using the class
name -which would defeat the purpose. I cannot use type patterns in advice,
rigth ? Can anyone provide any hints ? Using aspectJ, a sintatically wrong
expression of my needs would be:

package my.package;

privileged aspect TraceEnterLeave
{
	pointcut method(): within(my.package..*) && execution(* *(..));
	
	before(): method() 
	{
	
(my.package..*).logger.enter(thisJoinPointStaticPart.getSignature().getName(
) ,
		thisJoinPoint.getArgs());
	}
		
	after() returning(Object o): method() 
	{
	
(my.package..*).logger.leave(thisJoinPointStaticPart.getSignature().getName(
), o);
	}	
}

A related question would be how to migrate the static logger declaration in
each class to that tracing aspect ? Could I use a type pattern to get the
class name to instatiate each logger ?

Thanks in advance.
