Spring-异常抛出增强

实现org.springframework.aop.ThrowsAdvice;

package com.testApi.throwsAdvice;

import org.springframework.aop.ThrowsAdvice;

import java.lang.reflect.Method;

public class TransateManage implements ThrowsAdvice {

    //方法的签名必须符合规范
    //1。方法名必须是afterThrowing
    //2。第四个参数必须是Thowable或者其子类,前三个参数要么都提供,要么都不提供
    //同一个异常增强中可以有多个afterThrowing方法,会自动按照最匹配的方法进行增强
    public void afterThrowing(Method method,Object[] args,Object ob,Throwable throwable){
        System.out.println("========");
        System.out.println(method.getName());
        System.out.println("抛出异常"+throwable);
        System.out.println("做其他工作。。。");

    }

    public void afterThrowing(Method method,Object[] args,Object ob,RuntimeException e){
        System.out.println("========");
        System.out.println(method.getName());
        System.out.println("抛出异常"+e.getMessage());
        System.out.println("做其他工作。。。");
    }
}

beans.xml

<?xml version="1.0" encoding="utf-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<!--            增强类-->
    <bean id="throwableAdvice" class="com.testApi.throwsAdvice.TransateManage"/>
    <bean id="target2" class="com.testApi.beforeAdvice.SuperWaiter"/>
    <bean id="waiter" class="org.springframework.aop.framework.ProxyFactoryBean"
          p:interceptorNames="throwableAdvice"
          p:target-ref="target2"
          p:proxyTargetClass="true"/>

</beans>

接口:

package com.testApi.beforeAdvice;

public interface Waiter {
    void greetingTo(String name);

    void serveTo(String name);
}

实现类:

package com.testApi.beforeAdvice;

public class SuperWaiter implements Waiter {
    @Override
    public void greetingTo(String name) {
        System.out.println("greeting to" +name);
        throw new RuntimeException("运行异常");
    }

    @Override
    public void serveTo(String name) {
        System.out.println("serve to"+name);
    }
}

测试类:

    @Test
    public void test5(){
        ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext("beans.xml");

        Waiter waiter=(Waiter) context.getBean("waiter");
        waiter.greetingTo("异常测试");
    }

输出:

greeting to异常测试
========
greetingTo
抛出异常运行异常
