spring+mybatis+druid+mysql+maven事务配置

1、首先pom.xml文件里面需要用到的jar配置：

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>4.0.3.RELEASE</version>
</dependency>

<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>0.2.9</version>
</dependency>

<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.0.5</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>3.2.6.RELEASE</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>4.0.3.RELEASE</version>
</dependency>

<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.2.1</version>
</dependency>

<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.2.3</version>
</dependency>

2、config.properties内容

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.1.133:3306/salt?characterEncoding=utf-8
jdbc.user=root
jdbc.password=root1234

3、applicationContext.xml文件内容

<?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"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="

<context:property-placeholder location="classpath:config.properties" />

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

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<property name="driverClassName" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.user}" />
<property name="password" value="${jdbc.password}" />

<tx:advice id="userTxAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="delete*" propagation="REQUIRED" read-only="false" rollback-for="java.lang.Exception" no-rollback-for="java.lang.RuntimeException"/>

</tx:attributes>
</tx:advice>

<aop:config>
<aop:pointcut id="pc"
expression="execution(public * com.hskj.service.*.*(..))" />
<aop:advisor pointcut-ref="pc" advice-ref="userTxAdvice" />
</aop:config>

4、MyBatis-Configuration.xml文件内容：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<mappers>
<mapper resource="UserDaoMapper.xml"/>
</mappers>
</configuration>

5、UserDaoMapper.xml文件内容如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.hskj.mapper.UserMapper">

<insert id="insertUser" parameterMap="parameterMapUser">
INSERT INTO user(id,name)
VALUES(?,?)
</insert>
<select id="countAll" resultType="int">
select count(*) c from user;
</select>
<select id="getAllUser" resultMap="resultMapUser">
SELECT * FROM user
</select>
<select id="getById" parameterType="String" resultMap="resultMapUser">
SELECT * FROM user
WHERE id=#{value}
</select>
<delete id="deleteUser" parameterType="String">
DELETE FROM user
WHERE id=#{value}
</delete>
<update id="updateUser" parameterType="java.util.Map">
UPDATE user
SET name=#{name}
WHERE id=#{id}
</update>
</mapper>

6、数据库建表语句：

----------------------------

Table structure for `user`

----------------------------

DROP TABLE IF EXISTS `user`;

CREATE TABLE `user` (

`id` varchar(20) NOT NULL,

`name` varchar(20) default NULL,

PRIMARY KEY (`id`)

) ENGINE=InnoDB DEFAULT CHARSET=gb2312;

-- ----------------------------

-- Records of user

-- ----------------------------

INSERT INTO `user` VALUES ('001', '方舟子');

INSERT INTO `user` VALUES ('002', '小红');

INSERT INTO `user` VALUES ('003', '樱木滑到');

INSERT INTO `user` VALUES ('005', '桃木');

INSERT INTO `user` VALUES ('1', '张三');

INSERT INTO `user` VALUES ('2', '李四');

　　|--com.hskj.serviceImpl

　　　　　|--UserServiceImpl.java内容如下：

package com.hskj.serviceImpl;

import java.util.Map;
