mybatis xml配置文件模版

1、mybatis核心配置文件书写（SqlMapConfig.xml）

<?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>
<environments default="development">
<environment id="development">
<!--使用jdbc事务管理 -->
<transactionManager type="JDBC"/>
<!-- 数据库连接池 -->
<dataSource type="POOLED">
<property name="driver" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/mybatis?characterEncoding=utf-8"/>
<property name="username" value="root"/>
<property name="password" value="1234"/>
</dataSource>
</environment>
</environments>
<!-- 引入映射配置文件 -->
<mappers>
<mapper resource="cn/zhku/jsj/mybatis/pojo/User.xml"/>
</mappers>
</configuration>

2、mybatis映射配置文件书写（User.xml）

<?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">

<!-- namespace：命名空间，用于隔离sql-->
<mapper namespace="user">
<select id="findUserByUsername" parameterType="String" resultType="cn.zhku.jsj.mybatis.pojo.User">
select * from user where username like ‘%${value}%‘
</select>
</mapper>
