## 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.
