关于Springboot+MySQL的数据批量插入

Ⅰ：依赖：只需普通的mysql，数据源，JDBC,数据源连接等依赖即可，不需另外添加依赖
Ⅱ：sql语句：

    
    
    insert into st_teacher (id, create_by, create_time,
      update_by, update_time, version,
      name, password, icon,
      role_id,logins)
    values (#{teacher.id,jdbcType=VARCHAR}, #{teacher.createBy,jdbcType=VARCHAR}, #{teacher.createTime,jdbcType=TIMESTAMP},
      #{teacher.updateBy,jdbcType=VARCHAR}, #{teacher.updateTime,jdbcType=TIMESTAMP}, #{teacher.version,jdbcType=INTEGER},
      #{teacher.name,jdbcType=VARCHAR}, #{teacher.password,jdbcType=VARCHAR}, #{teacher.icon,jdbcType=VARCHAR},
      #{teacher.roleId,jdbcType=VARCHAR},#{teacher.logins,jdbcType=INTEGER})
  

//批量插入语句
    
        insert into st_teacher (id, create_by, create_time,
        update_by, update_time, version,
        name, password, icon,
        role_id,logins) values
        
            (#{teacher.id,jdbcType=VARCHAR}, #{teacher.createBy,jdbcType=VARCHAR}, #{teacher.createTime,jdbcType=TIMESTAMP},
            #{teacher.updateBy,jdbcType=VARCHAR}, #{teacher.updateTime,jdbcType=TIMESTAMP}, #{teacher.version,jdbcType=INTEGER},
            #{teacher.name,jdbcType=VARCHAR}, #{teacher.password,jdbcType=VARCHAR}, #{teacher.icon,jdbcType=VARCHAR},
            #{teacher.roleId,jdbcType=VARCHAR},#{teacher.logins,jdbcType=INTEGER})
        
    

对应关系：

注意：在批量插入中若想调用方法属性必须使用collection对应的值加上点获取，如上图片中，否则报以下异常：
org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.binding.BindingException: Parameter ‘id’ not found. Available parameters are [collection, list]

Ⅲ：Mapper接口：

package com.luntek.platform.ic_manufacturing_platform.mapper.admin;

import com.luntek.platform.ic_manufacturing_platform.entity.Teacher;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * @author Czw
 * @Description TODO
 * @Date 2019/4/12 0012 下午 1:23
 */
@Repository
public interface AdminMapper {

    /**
     * 单个增加老师
     * @param teacher
     * @return
     */
    Integer addSingleTeacher(@Param("teacher") Teacher teacher);

    /**
     * 批量添加老师用户
     * @param list
     * @return
     */
    Integer addBatchTeacher(List list);

}
