附上一份mybatis mapper xml文件的模版内容，自己写的不喜勿喷。有用点个赞再走。

<?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="">

<!-- type of resultMap usually is a model customized by developer. -->              

<resultMap id="" type="">

        <!-- jdbcType of result is a data type of database. -->

        <result column="" property="" jdbcType=""/>

    </resultMap>

    <!-- parameterType of select can be a customized model or a primitive type. -->

    <select id="" parameterType="" resultMap=""> </select>

    <insert id="" keyProperty="" parameterType="" useGeneratedKeys="true"> </insert>

    <update id="" parameterType=""> </update>

    <delete id="" parameterType=""> </delete>

</mapper>

然后去文件夹创建即可：
