java - java中如何拦截特定接口(interface)？

Question

在MyInterceptor中，Ifclocal或IfcRemote哪个接口(interface)调用了MyEjb中的doStuff方法？有可能知道你的bean是通过哪个“ channel ”被调用的吗？我需要知道哪个依赖注入(inject)调用了该方法。

@Local
public interface IfcLocal {
void doStuff(String s);
}

@Remote
public interface IfcRemote {
  void doStuff(String s);
}

@Stateless
@Interceptors({ MyInterceptor.class })
public class MyEjb implements IfcLocal, IfcRemote {
  @Override
  public void doStuff(String s) {
     System.out.println(s);
  }
}

public class MyManagedBean {
  @EJB private ifcLocal ifcLocal;
  @EJB private IfcRemote ifcRemote;

  public void go() {
    ifcLocal.doStuff("xxx");
    ifcRemote.doStuff("xxx");
  }
}

public class MyInterceptor {
  @AroundInvoke
  public Object intercept(InvocationContext inv) throws Exception {
    // ??? who invoked ???
    System.out.prinln(inv.getTarget().getClass()); // print MyEjb 
  }
}

注入(inject)@Resource private SessionContext sessionContext;在MyInterceptor 。之后:Class<?> interfaceReference = sessionContext.getInvokedBusinessInterface() .
