ThrowsAdvice不起作用解决方案

ThrowsAdvice不起作用
我定义了一个类，实现了ThrowsAdvice接口，在afterThrowing方法里输出“拦截异常”，可它不起作用，控制台只是输出普通的异常信息，没有输出我自己写的“拦截异常”几个字

Hi类

Java code

public class Hi {    public  void sayHI(){                System.out.println("i say hi");        try {            throw new Exception("my exception");        } catch (Exception e) {            e.printStackTrace();        }    }}

Java code

import org.springframework.aop.ThrowsAdvice;public class MyThrowsAdvice implements ThrowsAdvice{    public void afterThrowing(Exception ex){        System.out.println("拦截异常");        System.out.println(ex);            }}
