@AspectJ syntax for "after() : staticinitialization(*)"

I\'m trying to implement a tracing aspect using the pertypewithin instantiation model. In this way, I\'ll be able to use one logger per class per type.

I'm trying to implement a tracing aspect using the pertypewithin instantiation model. In this way, I'll be able to use one logger per class per type.

From some examples arround the we I can find this code to init the logger:

public abstract aspect TraceAspect pertypewithin(com.something.*) {
    abstract pointcut traced();
    after() : staticinitialization(*) {
        logger = Logger.getLogger(getWithinTypeName());
    }
    before() : traced() {
        logger.log(...);
    }
    //....
}

unfortunately, I'm not able to fully translate thi开发者_Go百科s to the @AspectJ syntax (it's a project requirement outside my control), especially the part in with I need to setup the logger, executing that code only once.

Is this possible?

Thanks,


@Aspect("pertypewithin(com.something.*))")
public abstract class TraceAspect {

Logger logger;

@Pointcut
public abstract void traced();

@Pointcut("staticinitialization(*)")
public void staticInit() {
}

@After(value = "staticInit()")
public void initLogger(JoinPoint.StaticPart jps) {
    logger = Logger.getLogger(jps.getSignature().getDeclaringTypeName());
}

@Before(value = "traced()")
public void traceThatOne(JoinPoint.StaticPart jps) {
    logger.log(jps.getSignature().getName());
}
}
