mybaties uuid使用

上源码

TestMapper.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="com.example.demo.dao.TestMapper">
    <resultMap id="BaseResultMap" type="com.example.demo.entry.Test">
        <id column="id" jdbcType="VARCHAR" property="id" />
        <result column="name" jdbcType="VARCHAR" property="name" />
    </resultMap>
    <insert id="insert">
        <selectKey keyProperty="id" resultType="java.lang.String" order="BEFORE">
            SELECT  uuid()
        </selectKey>
        insert into test (id,name) values(#{id},#{name});
    </insert>
</mapper>

上面红色要注意的,其他和平时差不多,id的话是在Test类里面id属性。select uuid()直接生成uuid

TestMapper.java

package com.example.demo.dao;

import com.example.demo.entry.Test;

/**
 * @program: demo
 * @description
 * @author: dajitui
 * @create: 2018-06-16 11:52
 **/
public interface TestMapper {

    int insert(Test test);
}

然后单元测试,注入mapper应该简单的。
