實體類:

import java.io.Serializable;
public class AttachmentTable implements Serializable {
    private static final long serialVersionUID = 8325882509007088323L;
    private Integer id;
    // 附件名稱
    private String name;
    // 日誌ID
    private Integer logid;
    // 附件URL
    private String url;

    // getter/setter.......
}

Mapper介面:

import java.util.List;
import model.AttachmentTable;
public interface AttachmentTableMapper {
　　int insert(AttachmentTable record);
　　void insertByBatch(List<AttachmentTable> attachmentTables);
}

Mapper.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="mapper.AttachmentTableMapper">
    <resultMap id="BaseResultMap" type="model.AttachmentTable">
        <id column="id" jdbcType="INTEGER" property="id" />
        <result column="name" jdbcType="VARCHAR" property="name" />
        <result column="logID" jdbcType="INTEGER" property="logid" />
    </resultMap>
    <resultMap extends="BaseResultMap" id="ResultMapWithBLOBs" type="model.AttachmentTable">
        <result column="url" jdbcType="LONGVARCHAR" property="url" />
    </resultMap>
    <sql id="Base_Column_List">
        id, name, logID
    </sql>
    <sql id="Blob_Column_List">
        url
    </sql>
    <insert id="insert" parameterType="model.AttachmentTable">
        insert into attachment_table (id, name, logID,url)
        values (#{id,jdbcType=INTEGER}, #{name,jdbcType=VARCHAR}, #{logid,jdbcType=INTEGER},#{url,jdbcType=LONGVARCHAR})
    </insert>
    <insert id="insertByBatch" parameterType="java.util.List">
        insert into attachment_table (name, logID,url)
        values
        <foreach collection="list" item="item" index="index" separator=",">
            (#{item.name,jdbcType=VARCHAR}, #{item.logid,jdbcType=INTEGER},#
 
{item.url,jdbcType=LONGVARCHAR})
        </foreach>
    </insert>
</mapper>

【注：標紅的地方是需要注意的地方,我第一次做時直接“#{name,jdbcType=VARCHAR}”,沒有加字首“item”,導致報錯“找不到name”】

 （二）多引數批量刪除示例

package com.vrv.linkdood.app.workreport.demomodule.mapper;import org.apache.ibatis.annotations.Param;public interface AttachmentTableMapper {
    void deleteByLogIdAndNames(@Param("logid") Integer logID, @Param("names") String[] names);
}

    <delete id="deleteByLogIdAndNames">
        delete from attachment_table
        where logid = #{logid,jdbcType=INTEGER} AND NAME IN
        <foreach collection="names" item="item" index="index" open="(" close=")" separator=",">
            #{item}
        </foreach>
    </delete>
