mybatis配置約束config，mapper

MyBatis 主配置文件 config.xml（這里可以自己起，不過后面帶上Config.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>
<!-- 這里寫配置內容 -->
</configuration>

MyBatis 映射文件 mapper.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">
<mapper namespace="命名空間">
<!-- SQL語句 -->
</mapper>
