类 ThrowsAdviceInterceptor

java.lang.Object
cn.taketoday.aop.framework.adapter.ThrowsAdviceInterceptor
所有已实现的接口:
AfterAdvice, Advice, Interceptor, MethodInterceptor
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 Framework users.

    • invoke

      @Nullable public Object invoke(MethodInvocation mi) throws Throwable
      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.
