Class Inheritance
All Implemented Interfaces
org.springframework.aop.AfterAdvice, org.aopalliance.aop.Advice, org.aopalliance.intercept.MethodInterceptor, org.aopalliance.intercept.Interceptor
Imports
java.lang.reflect.InvocationTargetException, .Method, java.util.HashMap, .Map, org.aopalliance.intercept.MethodInterceptor, .MethodInvocation, org.apache.commons.logging.Log, .LogFactory, org.springframework.aop.AfterAdvice, org.springframework.aop.framework.AopConfigException, org.springframework.lang.Nullable, org.springframework.util.Assert
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.

public Object invoke(MethodInvocation mi) throws Throwable

Implements org.aopalliance.intercept.MethodInterceptor.invoke.

Doc from org.aopalliance.intercept.MethodInterceptor.invoke.

Implement this method to perform extra treatments before and after the invocation. Polite implementations would certainly like to invoke Joinpoint#proceed().

Parameters
mi:MethodInvocation

the method invocation joinpoint

Returns:Object

the result of the call to Joinpoint#proceed(); might be intercepted by the interceptor
