spring之aop（ThrowsAdvice）拦截指定方法的异常

近段时间需要对程序的异常做统一的处理，比如写日志或者发送邮件，在网上找了下aop貌似可以解决，经过不懈努力，终于完成了这个效果，异常统一发送邮件，迅速知道异常所在，下面看代码。

spring的配置文件：

<!-- 异常集中捕获-->
    <!-- 自定义拦截异常通知类 -->
    <bean id = "aopTest" class="com.daja.paymp.infrastructure.scheduling.service.impl.SpringAopTest"/>
    
    <!-- 自定义异常通知类 -->
    <bean id="customAdvice" class="com.daja.paymp.presentation.interceptor.ExceptionThrowsAdvice" />
    <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"></bean> 
    <bean class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">
        <property name="advice">
            <ref bean="customAdvice"/>
        </property>
        <property name="patterns">
            <value>com\.daja\.paymp\.infrastructure\.scheduling\.service\.AutoJobService\.work</value>
        </property>
    </bean>

ExceptionThrowsAdvice.java

package com.daja.paymp.presentation.interceptor;
 
import java.lang.reflect.Method;
 
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.aop.ThrowsAdvice;
 
import com.daja.paymp.infrastructure.exception.CustomException;
 
/**
 * 异常拦截类 aop spring
 * 
 * @author smotive
 * 
 */
 
public class ExceptionThrowsAdvice implements ThrowsAdvice {
    Logger logger = LoggerFactory.getLogger(ExceptionThrowsAdvice.class);
 
    // Second preference
    public void afterThrowing(Method m, Object args[], Object target,
            Throwable e) {
        try {
            throw new CustomException(e,"自动任务出现异常");
        } catch (CustomException e1) {
            e1.printStackTrace();
        }
    }
}

接口类： AutoJobService.java

package com.daja.paymp.infrastructure.scheduling.service;
 
/**
 *  自动任务公共接口
 * @author smotive
 *
 */
public interface AutoJobService  {
    /**
     * 自动任务公共执行方法
     */
    public void work()throws Exception;
}

实现类：SpringAopTest.java

package com.daja.paymp.infrastructure.scheduling.service.impl;
 
import org.springframework.stereotype.Service;
 
import com.daja.paymp.infrastructure.scheduling.service.AutoJobService;
 
 
public class SpringAopTest implements AutoJobService {
 
    @Override
    public void work(){
        System.out.print("aop拦截测试方法进入"+(1/0));
    }
}

测试方法类：

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
 
import com.daja.paymp.infrastructure.scheduling.service.AutoJobService;
public class AopTest {
 
    public static void main(String args[])
    {
        ApplicationContext context = new FileSystemXmlApplicationContext("classpath:applicationContext-aop.xml");
 
        AutoJobService inter =(AutoJobService)context.getBean("aopTest");
        try {
            inter.work();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

运行结果：

当指定的方法抛出异常后，spring就会拦截到，做出相应的动作，系统加入这个，出现问题就可以及时察觉了，O(∩_∩)O哈哈~
