How can I intercept a exception just when it occurred?

[Wuaner]

Some code like this:

public class A {

  @Autoware
  private B b;  

  public void a() {
    //AAA: some logic process that maybe throw exception
    b.b();
  }

}

public class B {
  
  public void b() {
    //BBB: some logic process maybe also throw exception
  }
  
}

Both exceptions in A.a() and B.b() need to be intercept, so i use @AfterThrowing annotation do it. but the question is, when i call A.a() in other code and exception has occurred in B.b(), the Advice will execute twice! because exception that occurred in B.b() was propagating to its caller A.a().

I can't swallow the exception silently, because i use spring-amqp, above codes is on Consumer side, i need some message processing that based on the exceptions that occurred in Consumer.

So, How can i intercept a exception just when it occurred? ignore propagation of it.


Any reply is greatly appreciated.
