spring中管理事务的方式

这里写了三种方式

        1、 编码式

                    1、将核心事务管理器配置到spring容器

                   2.配置TransactionTemplate模板

       

                  3.将事务模板注入Service

       

                  4.在Service中调用模板

       2、XML配置

               这里我就直接把代码放这了

先看通知类

package com.hd.springAop;

import org.aopalliance.aop.Advice;
import org.aspectj.lang.ProceedingJoinPoint;

public class MyAdvice implements Advice {
    public void abc(){
        System.out.println("在调用切点方法前调用");
    }
    public void after(){
        System.out.println("有异常也正调用");
    }
    public void afterReturning(){
        System.out.println("有异常就不调用");
    }
    public void afterThrowing(){
        System.out.println("有异常就调用");
    }
    public Object around(ProceedingJoinPoint joinPoint) throws Throwable {
        System.out.println("开启事务");
        Object proceed = null;
        try {
            proceed = joinPoint.proceed();
            System.out.println("提交事务");
        } catch (Throwable throwable) {
            throwable.printStackTrace();
            System.out.println("回滚事务");
        }
        return proceed;
    }
}

然后是配置

<?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:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">

    <context:component-scan base-package="com.hd.springAop"></context:component-scan>

        <!--通知-->
    <bean name="myAdvice" class="com.hd.springAop.MyAdvice"></bean>
        <!--织入-->
    <aop:config>
           <!--
           void com.hd.springAop.UserServiceImpl.add()
           * com.hd.springAop.UserServiceImpl.*()
           * com.hd.springAop.*ServiceImpl.*(..)
           -->
           <!--切点-->
           <aop:pointcut id="pt" expression="execution(* com.hd.springAop.*ServiceImpl.*(..))"></aop:pointcut>

           <!--切面 ：通知+切点-->
           <aop:aspect ref="myAdvice" >
               <aop:before  method="abc" pointcut-ref="pt"></aop:before>
               <aop:after-throwing method="afterThrowing" pointcut-ref="pt"></aop:after-throwing>
               <aop:after method="after" pointcut-ref="pt"></aop:after>
               <aop:after-returning method="afterReturning" pointcut-ref="pt"></aop:after-returning>
               <aop:around method="around" pointcut-ref="pt"></aop:around>
           </aop:aspect>
       </aop:config>
</beans>

要增加的service

package com.hd.springAop;

import org.springframework.stereotype.Service;

@Service("userService")
public class UserServiceImpl implements UserService {
    @Override
    public void add() {
//        System.out.println("开启事务");
        System.out.println("执行添加");
//        System.out.println("回滚事务");
    }

    @Override
    public void delete() {
//        int i = 1/0;
//        System.out.println("开启事务");
        System.out.println("执行删除");
//        System.out.println("回滚事务");
    }

    @Override
    public void update() {
//        System.out.println("开启事务");
        System.out.println("提交事务");
//        System.out.println("回滚事务");
    }

    @Override
    public void get() {
        System.out.println("开启事务");
        System.out.println("提交事务");
        System.out.println("回滚事务");
    }
}

service接口

package com.hd.springAop;

public interface UserService {
    void add();
    void delete();
    void update();
    void get();
}

这就是springaop配置的使用版

还有一种注解模式在这就不写了想看的可以私聊我
