mapper.xml内容

因为找不到mapper.xml 的文件类型,所以自己加。。。。

<?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指向mapper.xml所对应的Mapper接口-->
<mapper namespace="com.bbs.bbs.mapper.StudentMapper">

    
</mapper>
