mybatis 批量将list数据插入到数据库的实现

这篇文章主要介绍了mybatis 批量将list数据插入到数据库的实现，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧

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 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} )
