ThrowsAdviceInterceptor (Spring Framework 4.3.30.RELEASE API)

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

所有已实现的接口:
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.

    从接口复制的说明: MethodInterceptor
    Implement this method to perform extra treatments before and after the invocation. Polite implementations would certainly like to invoke Joinpoint.proceed().
    指定者:
    invoke 在接口中 MethodInterceptor
    参数:
    mi - the method invocation joinpoint
    返回:
    the result of the call to Joinpoint.proceed(); might be intercepted by the interceptor
    抛出:
    Throwable - if the interceptors or the target object throws an exception
