Java 方法实现的切入点

我创建了一个带有指向注释方法的切入点的方面。作为

JoinPoint

我得到的是来自接口的方法声明，而不是方法实现。所以，当我想要得到带注释的方法参数时，我必须在接口中而不是在实现中添加注释

@AfterReturning(value = "@annotation(pl.styall.scylla.security.authorization.acl.AclSecure) && @annotation(aclSecure)", argNames = "jp,aclSecure,retVal", returning = "retVal")
public void addObjectAndEntry(JoinPoint jp, AclSecure aclSecure,
        Object retVal) {
    System.out.println(jp.toLongString());
    MethodSignature signature = (MethodSignature) jp.getSignature();
    Method method = signature.getMethod();
    Annotation[][] methodAnnotations = method.getParameterAnnotations();

methodAnnotations

如果是外接程序方法实现，则没有注释。正确的切入点是什么

final String methodName = pjp.getSignature().getName();
final MethodSignature methodSignature = (MethodSignature)pjp.getSignature();
Method method = methodSignature.getMethod();
if (method.getDeclaringClass().isInterface()) {
    method = pjp.getTarget().getClass().getDeclaredMethod(methodName, method.getParameterTypes());    
}
