1、首先pom.xml文件里面需要用到的jar配置:
<!-- spring事务,包含了@Transactional标注 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>4.0.3.RELEASE</version>
</dependency>
<!-- 数据库连接池 -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>0.2.9</version>
</dependency>
<!-- mysqljdbc驱动 ,这个是数据库连接池需要的-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.0.5</version>
</dependency>
<!-- 事务:DataSourceTransactionManager -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>3.2.6.RELEASE</version>
</dependency>
<!-- 事务aop:config -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>4.0.3.RELEASE</version>
</dependency>
<!-- 事务SqlSessionFactoryBean -->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.2.1</version>
</dependency>
<!-- 要使用到mybatis,必须要用mybatis这个包 -->
<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>
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">
<parameterMap type="com.hskj.domain.User" id="parameterMapUser">

<parameter property="name"/>
</parameterMap>
<resultMap type="com.hskj.domain.User" id="resultMapUser">
<result property="id" column="id"/>
<result property="name" column="name"/>
</resultMap>
<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

</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'
);
