Log4j and AOP, how to get actual class name

davioooh picture davioooh · Jul 16, 2012 · Viewed 11.5k times · Source

I'm implementing a logger as an aspect using Spring AOP and Log4J, but I've noticed that the class name in log file is always the LoggerAspect class name, so... is there a way to trace the actual class name in my log?

@Around("execution(* com.mycontrollerpackage.*.*(..))")
public Object aroundWebMethodE(ProceedingJoinPoint pjp) throws Throwable {      
    String packageName = pjp.getSignature().getDeclaringTypeName();
    String methodName = pjp.getSignature().getName();
    long start = System.currentTimeMillis();
    if(!pjp.getSignature().getName().equals("initBinder")) {
       logger.info("Entering method [" + packageName + "." + methodName +  "]");
    }
    Object output = pjp.proceed();
    long elapsedTime = System.currentTimeMillis() - start;
    if(!methodName.equals("initBinder")) {
       logger.info("Exiting method [" + packageName + "." + methodName + "]; exec time (ms): " + elapsedTime);
    }
    return output;
}
