mybatis 批量将list数据插入到数据库的实现

随着业务需要，有时我们需要将数据批量添加到数据库，mybatis提供了将list集合循环添加到数据库的方法。具体实现代码如下:

1、mapper层中创建 insertForeach(List < Fund > list) 方法,返回值是批量添加的数据条数

 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 list);
 }

Fund类代码如下:

 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语句如下:

 
  insert into fund
  ( id,fund_name,fund_code,date_x,data_y,create_by,create_date,update_by,update_date,remarks,del_flag)
  values
  
  (
   #{item.id},
   #{item.fundName},
   #{item.fundCode},
   #{item.dateX},
   #{item.dataY},
   #{item.createBy},
   #{item.createDate},
   #{item.updateBy},
   #{item.updateDate},
   #{item.remarks},
   #{item.delFlag}
  )
