Class ThrowsAdviceInterceptor

java.lang.Object
  org.springframework.aop.framework.adapter.ThrowsAdviceInterceptor

All Implemented Interfaces:

Advice, Interceptor, MethodInterceptor, AfterAdvice

---

public class ThrowsAdviceInterceptor
extends Object
implements MethodInterceptor, AfterAdvice

Interceptor to wrap an after-throwing advice.

The signatures on handler methods on the ThrowsAdvice implementation method argument must be of the form:
void afterThrowing([Method, args, target], ThrowableSubclass);

Only the last argument is required.

Some examples of valid methods would be:

public void afterThrowing(Exception ex)

public void afterThrowing(RemoteException)

public void afterThrowing(Method method, Object[] args, Object target, Exception ex)

public void afterThrowing(Method method, Object[] args, Object target, ServletException ex)

This is a framework class that need not be used directly by Spring users.
