Acerca de la inserción de datos por lotes Springboot + MySQL

Ⅰ: Dependencia: solo se requieren mysql ordinario, fuente de datos, JDBC, conexión de fuente de datos y otras dependencias, no se requieren dependencias adicionales
Ⅱ: declaración sql:

<?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.luntek.platform.ic_manufacturing_platform.mapper.admin.AdminMapper">

    <!--   Integer addSingleTeacher(@Param("teacher") Teacher teacher) -->
    <insert id="addSingleTeacher" parameterType="com.luntek.platform.ic_manufacturing_platform.entity.Teacher">
    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})
  </insert>

//批量插入语句
    <insert id="addBatchTeacher" parameterType="java.util.List">
        insert into st_teacher (id, create_by, create_time,
        update_by, update_time, version,
        name, password, icon,
        role_id,logins) values
        <foreach collection="list" item="teacher" index="index"
                 separator=",">
            (#{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})
        </foreach>
    </insert>

</mapper>

Correspondencia:

Nota: Si desea llamar al atributo del método en la inserción del lote, debe usar el valor correspondiente a la colección más un punto para obtenerlo, como se muestra en la imagen de arriba, de lo contrario se reportará la siguiente excepción:
org.mybatis.spring.MyBatisSystemException: la excepción anidada es org.apache.ibatis .binding.BindingException: No se encontró el parámetro "id". Los parámetros disponibles son [colección, lista]

Ⅲ: Interfaz del mapeador:

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;

/**

@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<Teacher> list);
