Java MyBatis XXXMapper.xml中的批量插入

1.1、准备环境

这篇文章的批量操作都将是针对User用户表，下面给出相关的代码。

SQL建表语句

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键ID',
  `username` varchar(50) DEFAULT NULL COMMENT '用户名称',
  `password` varchar(50) DEFAULT NULL COMMENT '密码',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3010 DEFAULT CHARSET=utf8;

1.2、批量新增

<?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.mybatis.demo.mapper.UserMapper">
    <!-- 批量插入 -->
    <insert id="batchInsert" parameterType="com.mybatis.demo.domain.User">
        insert into user(id, username, password)
        values
        <foreach collection="userList" item="user" separator=",">
            (#{user.id},
            #{user.username},
            #{user.password})
        </foreach>
    </insert>
</mapper>
