1、实体类

package com.xw.model;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;import java.io.Serializable;@Data
@AllArgsConstructor
@NoArgsConstructor
public class ExcelBatchImportData implements Serializable {/*** 手机号*/private String preferentialPhone;/*** 车牌号*/private String preferentialCarNumber;/*** 优惠分组的id*/private String groupingId;/*** 创建时间*/private String createTime;/*** 修改时间*/private String modifyTime;}

2、controller

package com.xw.controller;import com.xw.service.GroupConfigService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
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.ResponseBody;
import org.springframework.web.multipart.MultipartFile;import java.util.HashMap;
import java.util.Map;@Controller
@RequestMapping("/rs")
public class TestController {/*** GroupConfigService groupConfigService*/@Autowiredprivate GroupConfigService groupConfigService;/*** logger*/private Logger logger = LoggerFactory.getLogger(TestController.class);/*** Excel导入* @param file 文件对象* @return Map<String, Object>*/@RequestMapping(value = "/importExcel",method = RequestMethod.POST)@ResponseBodypublic Map<String, Object> importExcel(@RequestParam("file") MultipartFile file){Map<String, Object> map = new HashMap<>();try {map = groupConfigService.importExcel(file);}catch (Exception e){map.put("status",-1);map.put("data", "导入异常");logger.error(e.getMessage(),e);}return map;}
}

3、service

package com.xw.service;import com.xw.mapper.GroupConfigMapper;
import com.xw.model.ExcelBatchImportData;
import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFDateUtil;

import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.multipart.MultipartFile;import java.text.DecimalFormat;
import java.text.SimpleDateFormat;
import java.util.*;@Service
public class GroupConfigService {/*** 定义全局的常量值*/private static final String XLS = "xls";/*** 定义全局的常量值*/private static final String XLSX = "xlsx";/*** GroupConfigDao groupConfigDao*/@Autowiredprivate GroupConfigMapper groupConfigMapper;/*** logger*/private Logger logger = LoggerFactory.getLogger(GroupConfigService.class);/*** Excel导入** @param file 文件对象* @return Map<String, Object>*/public Map<String, Object> importExcel(MultipartFile file) {List<ExcelBatchImportData> tblFixChangeList = new ArrayList<>();Map<String, Object> map = new HashMap<>();Workbook workbook = null;String filename = file.getOriginalFilename();try {if (filename != null) {if (filename.endsWith(XLS)) {// 2003workbook = new HSSFWorkbook(file.getInputStream());} else if (filename.endsWith(XLSX)) {// 2007workbook = new XSSFWorkbook(file.getInputStream());} else {throw new Exception("文件不是Excel文件");}} else {logger.error("文件为空");}// 获取sheetSheet sheet = workbook.getSheet("Sheet1");int lastRowNum = sheet.getLastRowNum();if (lastRowNum == 0) {throw new Exception("请填写行数");}for (int i = 1; i < lastRowNum + 1; i++) {Row row = sheet.getRow(i);if (row != null) {// 读取cell单元格内容ExcelBatchImportData tblFixChange = new ExcelBatchImportData();// 手机号String phone = getCellValue(row.getCell(0));tblFixChange.setPreferentialPhone(phone);// 车票号String carNumber = getCellValue(row.getCell(1));tblFixChange.setPreferentialCarNumber(carNumber);String groupId = getCellValue(row.getCell(2));tblFixChange.setGroupingId(groupId);// 日期格式化操作SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");String time = sdf.format(new Date());tblFixChange.setCreateTime(time);tblFixChange.setModifyTime(time);tblFixChangeList.add(tblFixChange);}}// 批量插入groupConfigMapper.addBatchMembers(tblFixChangeList);map.put("status", 1);map.put("data", "导入数据成功");} catch (Exception e) {map.put("status", -1);map.put("data", "导入数据异常");logger.error(e.getMessage(), e);}return map;}/*** 获取每个单元格内容** @param cell cell* @return String*/private String getCellValue(Cell cell) {// 单元格内容String value = "";if (cell != null) {// 以下是判断数据的类型switch (cell.getCellType()) {// 数字case HSSFCell.CELL_TYPE_NUMERIC:value = cell.getNumericCellValue() + "";// 判断cell是不是日期类型的if (HSSFDateUtil.isCellDateFormatted(cell)) {// 获取日期类型的单元格Date date = cell.getDateCellValue();if (null != date) {value = new SimpleDateFormat("yyyy-MM-dd").format(date);} else {value = "";}} else {value = new DecimalFormat("0").format(cell.getNumericCellValue());}break;// 字符串case HSSFCell.CELL_TYPE_STRING:value = cell.getStringCellValue();break;// Booleancase HSSFCell.CELL_TYPE_BOOLEAN:value = cell.getBooleanCellValue() + "";break;// 公式case HSSFCell.CELL_TYPE_FORMULA:value = cell.getCellFormula() + "";break;// 空格case HSSFCell.CELL_TYPE_BLANK:value = "";break;// 错误case HSSFCell.CELL_TYPE_ERROR:value = "非法字符";default:value = "未知类型";break;}}return value.trim();}
}

4、mapper

package com.xw.mapper;import com.xw.model.ExcelBatchImportData;
import org.apache.ibatis.annotations.Param;import java.util.List;public interface GroupConfigMapper {/*** 批量插入数据* @param excelBatchImportData tblFixChangeList*/void addBatchMembers(@Param("excelBatchImportData") List<ExcelBatchImportData> excelBatchImportData);
}

5、mapper.xml

<?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.xw.mapper.GroupConfigMapper"><insert id="addBatchMembers">insert into group_config(preferential_phone, preferential_carNumber, grouping_id, create_time, modify_time)values<foreach collection="excelBatchImportData" item="item" separator=",">(#{item.preferentialPhone},#{item.preferentialCarNumber},#{item.groupingId},#{item.createTime},#{item.modifyTime},)</foreach></insert></mapper>
