如何将自定义值传递给spring aop建议？

Question

If I take a service method named public void delete(int id); as the pointcut, I want to add an after-returning advice on it, but I don't know what kind of object was deleted(however, the servlet which called the service knows the type value), so I was wondering if I can pass a customized value to this after-returning advice when it is activated, like 'user' . I've already checked the related document on Spring's website and I still know nothing. I'd appreciate your answer, THX.

Answer 1

One solution but its required refactoring in Service method

1) Refactoring

public class DeleteRequest {
   String type;
   Long id;
}

public boolean delete(DeleteRequest request){ // impl}

2) Use Around Advice 2.1) Before proceeding method execution, read passed parameter & get to be deleted object for "XYZ" requirement. 2.2) Capture result of delete method execution IF its TRUE then DO your stuff

Note: I used this approach for deleted entity notification. So how we can get deleted entity information in after-advice, hence keep it entity information in before phase & use it in after-successful execution.
