说明简介：当你项目中集成以下功能，我们便可以避免因为excel导入到数据库功能编写过多的代码。
我们只需按照要求少量的在数据库编写配置信息。实现接口便可以完成导入，无需再写导入相关代码。
1、复用性强，适用于多场景。
2、支持多sheet导入到多表
3、支持合并单元格读取
4、支持空单元格
5、支持单元格输入now()字符串导入数据库为当前时间LocaldateTime.now()
6、支持对每个字段编写检验规则，通过才会导入到数据库
7、包含日志表，方便查询
8、会生成临时表，以供参考

3、需要配置表实例

[pub_imp_excel_model]表配置实例

[pub_imp_excel_modelcol]表配置实例

[pub_imp_excel_valid_rule]表配置实例

4、使用mybatis-plus生成表对应的java代码

在PubImpExcelModelMapper.xml编写的动态sql如下，负责创建临时表，保存数据到临时表

<update id="createTable">create table ${tableName}(id int(11) comment '用于存储excel的rowindex',valid_res int default 1 null comment 'int(1)类型，1表示校验通过，2表示校验不通过',valid_tip varchar(3000) null comment '校验提示信息',<foreach collection="list" index="index" item="item" separator="," close="">${item.excelColumn} ${item.fieldType} null comment '动态生成字段'</foreach>);</update><insert id="saveData">insert into ${tableName} values<foreach collection="list" index="index" item="items" separator="," open="" close=""><!--        (1,'test', --><foreach collection="items" index="i" item="item" separator="," open="(" close=")"><choose><when test="item=='null'">NULL</when><otherwise>'${item}'</otherwise></choose></foreach></foreach></insert>

对应的mapper层写两个接口方法

void createTable(String tableName, List<PubImpExcelModelcol> list);Integer saveData(String tableName,List<List<String>> list);

PubImpExcelValidRuleMapper.xml的动态sql如下。查询库里的校验规则

<select id="getRuleByIds" resultType="java.util.Map">SELECT*FROMpub_imp_excel_valid_ruleWHEREvalid_code IN<foreach collection="list" index="i" item="item" separator="," open="(" close=")">#{item}</foreach>and state =1</select>

mapper对应的方法

List<Map<String, Object>> getRuleByIds(List<String> ids);

5、使用到的工具类

ReadExcelUtil

主要ReadExcelUtil负责校验查验excel字段数据

}

6、接口与实现代码

首先我们需要一个连接数据库的mapper
对用的mapper接口

Integer SavaData(String savetableName,String tableName, List excelColumnList, List colCodeList);

将临时表内的数据导入到正式库

    <insert id="SavaData">insert into ${savetableName}<foreach collection="colCodeList" item="item" index="index" open="(" separator="," close=")">${item}</foreach>select<foreach collection="excelColumnList" item="items" index="index" open="" separator="," close="">${items}</foreach>from${tableName}where valid_res = 1</insert>

需要实现的接口

package com.xjt.excel.service;import java.util.List;/*** @author xu* @Description* @createTime 2021年05月13日 13:39:00*/
public interface IImpExcelService {Integer importExcelToDb(String tableName, List excelColumnList,List colCodeList);
}

实现类

实现类我们只需要实现接口，并重写一个方法。
方法内调用以上写的mapper接口

@Service
public class UserServiceImpl implements  IImpExcelService {//需要注入之前写的mapper层对象调用SaveData方法连接数据库@Overridepublic Integer importExcelToDb(String tableName, List excelColumnList, List colCodeList) {return SavaData("user",tableName, excelColumnList, colCodeList);//第一个（'user'）参数为需要导入正式库的表名}
}

8、上传excel到数据库接口

9、接口测试

测试excel

model表配置

model_col表配置

Rule表配置

postman请求接口测试

成功！

返回类型

code：状态码
successImportCount：成功导入数
filePath：上传的文件保存的位置
temTableName：生成的临时表名
expendTime：导入耗时
status：状态

生成的临时表如下

查看正式库，数据已经导入

日志表记录数据如下

当你测试结果如以上所示。恭喜你，你已经集成动态导入。
