Getting the java.lang.reflect.Method from a ProceedingJoinPoint?

Solution 1:

Your method is not wrong, but there's a better one. You have to cast to MethodSignature

MethodSignature signature = (MethodSignature) joinPoint.getSignature();
Method method = signature.getMethod();

Solution 2:

You should be careful because Method method = signature.getMethod() will return the method of the interface, you should add this to be sure to get the method of the implementation class:

    if (method.getDeclaringClass().isInterface()) {
        try {
            method= jointPoint.getTarget().getClass().getDeclaredMethod(jointPoint.getSignature().getName(),
                    method.getParameterTypes());
        } catch (final SecurityException exception) {
            //...
        } catch (final NoSuchMethodException exception) {
            //...                
        }
    }

(The code in catch is voluntary empty, you better add code to manage the exception)

With this you'll have the implementation if you want to access method or parameter annotations if this one are not in the interface
