spring管理事务（基于xml方式）

1.

配置事务管理器

<bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager" id="dataSourceTransactionManager">
    <property name="dataSource" ref="Datasource"></property>
</bean>

2.开启事务注解

引入命名空间tx

xmlns:tx="http://www.springframework.org/schema/tx"
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd

开启事务注解

<tx:annotation-driven transaction-manager="dataSourceTransactionManager" ></tx:annotation-driven>

 配置好的xml文件

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

    <bean id="Datasource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="url" value="jdbc:mysql:///account"></property>
        <property name="username" value="root"></property>
        <property name="password" value="mysql"></property>
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
    </bean>

    <bean id="JdbcTample" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="Datasource"></property>
    </bean>

    <context:component-scan base-package="org.hxut.zyk" ></context:component-scan>

    <!--创建事务管理器-->
<bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager" id="dataSourceTransactionManager">
     <!--注入数据源-->
    <property name="dataSource" ref="Datasource"></property>
</bean>
<!--开启事务注解-->
<tx:annotation-driven transaction-manager="dataSourceTransactionManager" ></tx:annotation-driven>
</beans>

3.在要添加的事务的类上添加注解

@Transactional

这个注解加到类上：类中的所有方法都增加了事务

这个注解加到方法上：此方法添加了事务

注意：如果要添加的事务的类实现了一个接口，则需要在xml文件中加aop约束并加一句

<aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>

原因还不知道，可能是动态代理造成

package org.hxut.zyk.service;

import org.hxut.zyk.dao.AccountdaoImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.transaction.event.TransactionalEventListener;


@Service
@Transactional
public class AccountServiceImpl implements AccountService {
    @Autowired
    AccountdaoImpl accountdao;
    public  void change()
    {
        accountdao.add_lucky();
        int a=10/0;
        accountdao.less_mercy();
    }
}
