Please give me ideas, sample code. thank you.

You can inject JoinPoint object in the AOP method and use the APIs exposed by JoinPoint.

To get the method name on which the aspect is getting applied, you can use

joinPoint.getSignature().getName()

If you want generic advice to all the methods irrespective of the arguments size below is the code..

@Aspect
public class SomeAdvice{
   @Pointcut("execution(* com.xxxx.service.*Manager.*(..))")
    public void doSomething() {
    }

    @Before(value = "doSomething()", argNames = "joinPoint")
    public void beforeCall(JoinPoint joinPoint) {
        logger.debug("Method Name :" + joinPoint.getSignature().toShortString() + "| Args => " + Arrays.asList(joinPoint.getArgs()));
    }
}

and if you want advice to methods with specific arguments

.....

@Before(value="execution(* com.xxxxx.service.MessageServer.informAgent"
    + "(String)) && args(queryString)",argNames="joinPoint,queryString")
    public void beforeinformAgent(JoinPoint joinPoint,String queryString) {
        logger.trace("Method name="+joinPoint.getSignature().getName());
        logger.trace("Informing message server with query string :" + queryString);
    }

observe the "argNames" in the above code,joinPoint followed by the argument names.You can play with joinPoint now ...

Hope this helps you

I think this website will help you a lot. I recently came across this, Have a look at this. They have given the simple example for both Annotation driven and xml driven approaches.
