Mybatis 插入與批量插入以及多參數批量刪除

說明：mybatis實現數據的批量插入及刪除功能

一：批量插入

實體類:

package com.thinkgem.wlw.modules.midea.realtimedata.entity;

import com.thinkgem.wlw.common.persistence.DataEntity;

import java.util.Date;

/**

 * @Date: 2019/6/12 10:10
 */
public class Realtimedata extends DataEntity<Realtimedata> {
    private String code;
    private int device_param_id;
    private Double value;
    private Date time;

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public int getDevice_param_id() {
        return device_param_id;
    }

    public void setDevice_param_id(int device_param_id) {
        this.device_param_id = device_param_id;
    }

    public Double getValue() {
        return value;
    }

    public void setValue(Double value) {
        this.value = value;
    }

    public Date getTime() {
        return time;
    }

    public void setTime(Date time) {
        this.time = time;
    }
}

Mapper接口:

package com.thinkgem.wlw.modules.midea.realtimedata.dao;

import com.thinkgem.wlw.common.persistence.CrudDao;
import com.thinkgem.wlw.common.persistence.annotation.MyBatisDao;
import com.thinkgem.wlw.modules.midea.realtimedata.entity.Realtimedata;

import java.util.List;

/**
 * 實時表數據（模擬量參數）
 * @Author: zhouhe
 * @Date: 2019/6/12 10:11
 */
@MyBatisDao
public interface RealtimedataDao extends CrudDao<Realtimedata> {

    void insertByBatch(List<Realtimedata> xtd_device_data_monitor);
}

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="com.thinkgem.wlw.modules.midea.realtimedata.dao.RealtimedataDao">

    <insert id="insertByBatch" parameterType="java.util.List">
        insert into xtd_device_data_monitor (code,device_param_id,value,time)
        values
        <foreach collection="list" item="item" index="index" separator=",">
            (#{item.code,jdbcType=VARCHAR}, #{item.device_param_id,jdbcType=INTEGER},#{item.value,jdbcType=DOUBLE},now())
        </foreach>
    </insert>

</mapper>

二：多參數批量刪除示例

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>
