SpringBoot2.x使用EasyPOI导入Excel浅谈

SpringBoot2.x使用EasyPOI导入Excel浅谈

平时经常遇到客户要帮忙导入一些数据到数据库中，有些数据比较多有时候手动录入就会很耗时间，所以就自己写一个Excel导入的demo记录一下我对EasyPOI的误区；本文使用SpringBoot2.0,EasyPOI

开发框架

框架：SpringBoot2.0
java jdk 1.8
开发工具：Eclipse
数据库：Orcal

一.首先在pom.xml中导入EasyPOI的架包

pom.xml的主要文件信息如下：

<!-- easypoi -->
		<dependency>
            <groupId>cn.afterturn</groupId>
            <artifactId>easypoi-base</artifactId>
            <version>3.0.3</version>
        </dependency>
        <dependency>
            <groupId>cn.afterturn</groupId>
            <artifactId>easypoi-web</artifactId>
            <version>3.0.3</version>
        </dependency>
        <dependency>
            <groupId>cn.afterturn</groupId>
            <artifactId>easypoi-annotation</artifactId>
            <version>3.0.3</version>
        </dependency>

二.然后编写Controller

Controller：

/**
 * @author lr
 * @date 2018年12月26日 下午6:51:43
 * @version V1.0.0
 */
package com.louis.sql.tools.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;

import com.louis.sql.tools.model.LongHuaAreaDO;
import com.louis.sql.tools.result.HttpResult;
import com.louis.sql.tools.service.LongHuaAreaService;

@RestController
@RequestMapping("longhua")
public class LongHuaController {

    @Autowired
    private LongHuaAreaService longHuaAreaService;
    /**
     * @Title: listAllData
     * @Description: 查询处所有的数据并展示
     * @param @return  参数说明
     * @return HttpResult    返回类型
     * @throws
     */
    @RequestMapping(value = "/list", method = RequestMethod.GET)
    public HttpResult listAllData(){
        return HttpResult.ok(longHuaAreaService.listAll());
    }

    @RequestMapping(value = "/deleteByName", method = RequestMethod.DELETE)
    public HttpResult deleteByName(@RequestBody List<LongHuaAreaDO> records) {

        return HttpResult.ok(longHuaAreaService.deleteByName(records));
    }

    /**
     * @Title: importExcel
     * @Description: 导入Excel方法
     * @param @param file  参数说明
     * @return void    返回类型
     * @throws
     */
    @PostMapping("/importExcel")
    public void importExcel(@RequestParam("file") MultipartFile file) {
        String fileName = file.getOriginalFilename();
        try {
            longHuaAreaService.batchImport(fileName, file);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

三.接口LongHuaAreaService

/**
 * @author lr
 * @date 2018年12月26日 下午9:26:02
 * @version V1.0.0
 */
package com.louis.sql.tools.service;

import java.io.IOException;
import java.util.List;

import org.springframework.web.multipart.MultipartFile;

import com.louis.sql.tools.model.LongHuaAreaDO;

public interface LongHuaAreaService {

    /**
     * @Title: listAll
     * @Description: 查询所有的龙华区监管人员
     * @param @return  参数说明
     * @return String    返回类型
     * @throws
     */
    List<LongHuaAreaDO> listAll();

    /**
     * @Title: deleteByName
     * @Description: TODO(这里用一句话描述这个方法的作用)
     * @param @param records
     * @param @return  参数说明
     * @return String    返回类型
     * @throws
     */
    int deleteByName(List<LongHuaAreaDO> records);

    /**
     * @Title: delete
     * @Description: TODO(这里用一句话描述这个方法的作用)
     * @param @param record
     * @param @return  参数说明
     * @return int    返回类型
     * @throws
     */
    int delete(LongHuaAreaDO record);

    /**
     * @Title: batchImport
     * @Description: 导入Excel中的数据
     * @param @param fileName
     * @param @param file  参数说明
     * @return void    返回类型
     * @throws
     */
    void batchImport(String fileName, MultipartFile file) throws IOException, Exception;

}

四.实现方法LongHuaAreaServiceImpl

/**
 * @author lr
 * @date 2018年12月26日 下午9:26:50
 * @version V1.0.0
 */
package com.louis.sql.tools.service.impl;

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.multipart.MultipartFile;

import com.louis.sql.tools.dao.LongHuaAreaMapper;
import com.louis.sql.tools.model.LongHuaAreaDO;
import com.louis.sql.tools.service.LongHuaAreaService;

import cn.afterturn.easypoi.excel.ExcelImportUtil;
import cn.afterturn.easypoi.excel.entity.ImportParams;

@Service
public class LongHuaAreaServiceImpl implements LongHuaAreaService{

    @Autowired
    private LongHuaAreaMapper longHuaAreaMapper;

    @Override
    public List<LongHuaAreaDO> listAll() {

        return longHuaAreaMapper.listAll();
    }

    @Override
    public int delete(LongHuaAreaDO record) {
            return longHuaAreaMapper.deleteByName(record.getName());
    }

    @Override
    public int deleteByName(List<LongHuaAreaDO> records) {
        for (LongHuaAreaDO record : records) {
            delete(record);
        }
        return 1;
    }

    /*
     * Title: batchImport
     *Description:
     * @param fileName
     * @param file
     * @see com.louis.sql.tools.service.LongHuaAreaService#batchImport(java.lang.String, org.springframework.web.multipart.MultipartFile)
     */
    @Transactional(readOnly = false,rollbackFor = Exception.class)
    @Override
    public void batchImport(String fileName, MultipartFile file) throws IOException, Exception {
        ImportParams params = new ImportParams();
        params.setTitleRows(0);
        params.setHeadRows(1);
        List<LongHuaAreaDO> list = ExcelImportUtil.importExcel(file.getInputStream(), LongHuaAreaDO.class, params);
        for (int i = 0; i <list.size() ; i++) {
            System.out.println(list.get(i));
            System.out.println(list.get(i).getId());
        }

    }

}

五.实体类方法LongHuaAreaDO

/**
 * @author lr
 * @date 2018年12月26日 下午6:32:48
 * @version V1.0.0
 */

注意：一定要有toString构造方法

六.要导入的Excel中的内容格式如下：

七.使用Swagger-ui的的接口方法进行导入

八.导入后的效果如下

目前只写到从Excel中读取到了数据，后续如何插入到数据库中大家可以自己完善一下
