小編給大家分享一下如何實現mybatis批量將list數據插入到數據庫，希望大家閱讀完這篇文章后大所收獲，下面讓我們一起去探討吧！
隨著業務需要，有時我們需要將數據批量添加到數據庫，mybatis提供了將list集合循環添加到數據庫的方法。具體實現代碼如下:
1、mapper層中創建 insertForeach(List < Fund > list) 方法,返回值是批量添加的數據條數
package com.center.manager.mapper;
import java.util.List;
import org.apache.ibatis.annotations.Mapper;
import com.center.manager.entity.Fund;
@Mapper
public interface FundMapper {
int insertForeach(List<Fund> list);
}Fund類代碼如下:
package com.center.manager.entity;
import java.util.Date;
public class Fund {
private String id;
private String fundName;
private String fundCode;
private String dateX;
private String dataY;
private String remarks;
private String createBy;
private Date createDate;
private String updateBy;
private Date updateDate;
private String delFlag;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getFundName() {
return fundName;
}
public void setFundName(String fundName) {
this.fundName = fundName;
}
public String getFundCode() {
return fundCode;
}
public void setFundCode(String fundCode) {
this.fundCode = fundCode;
}
public String getDateX() {
return dateX;
}
public void setDateX(String dateX) {
this.dateX = dateX;
}
public String getDataY() {
return dataY;
}
public void setDataY(String dataY) {
this.dataY = dataY;
}
public String getRemarks() {
return remarks;
}
public void setRemarks(String remarks) {
this.remarks = remarks;
}
public String getCreateBy() {
return createBy;
}
public void setCreateBy(String createBy) {
this.createBy = createBy;
}
public Date getCreateDate() {
return createDate;
}
public void setCreateDate(Date createDate) {
this.createDate = createDate;
}
public String getUpdateBy() {
return updateBy;
}
public void setUpdateBy(String updateBy) {
this.updateBy = updateBy;
}
public Date getUpdateDate() {
return updateDate;
}
public void setUpdateDate(Date updateDate) {
this.updateDate = updateDate;
}
public String getDelFlag() {
return delFlag;
}
public void setDelFlag(String delFlag) {
this.delFlag = delFlag;
}
}2、mybatis的xml文件中的insert語句如下:
<?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.center.manager.mapper.FundMapper">
<insert id="insertForeach" parameterType="java.util.List" useGeneratedKeys="false">
insert into fund
( id,fund_name,fund_code,date_x,data_y,create_by,create_date,update_by,update_date,remarks,del_flag)
values
<foreach collection="list" item="item" index="index" separator=",">
(
#{item.id},
#{item.fundName},
#{item.fundCode},
#{item.dateX},
#{item.dataY},
#{item.createBy},
#{item.createDate},
#{item.updateBy},
#{item.updateDate},
#{item.remarks},
#{item.delFlag}
)
</foreach>
</insert>
