需求：需要实现一个导出的接口，点导出同时导出5个Excel表格，五种表格的数据筛选不同数据

java">public String export(MarketReceiveVo query) {Date winApprovalStartDate = query.getWinApprovalStartDate();Date winApprovalEndDate = query.getWinApprovalEndDate();SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");String winApprovalStartDateStr = sdf.format(winApprovalStartDate);String winApprovalEndDateStr = sdf.format(winApprovalEndDate);// 根据日期获取团队详细信息List<MarketXxxxListVo> allAchievementExport = marketSysFrameworkService.getAllAchievement(winApprovalStartDate, winApprovalEndDate);//所有的List<MarketXxxxListVo> gManagerExportVo = marketSysFrameworkService.getGManager(winApprovalStartDate, winApprovalEndDate);// 副总的数据List<MarketXxxxListVo> leaderExports = marketSysFrameworkService.getLeaderExports(winApprovalStartDate, winApprovalEndDate);// 组长的数据List<MarketXxxxListVo> TeamMemberExport = marketSysFrameworkService.getTeamMemberExport(winApprovalStartDate, winApprovalEndDate);// 组员的数据List<MarketXxxxListVo> marketAchievementExport = marketSysFrameworkService.getDetailed(winApprovalStartDate, winApprovalEndDate); // 分配明细// 数据转换List<AllAchievementExportVo> exportVos = Optional.ofNullable(allAchievementExport).orElse(new ArrayList<>()).stream().map(source -> BeanUtil.convert(source, AllAchievementExportVo.class)).collect(Collectors.toList());List<GManagerExportVo> exportVosGManager = Optional.ofNullable(gManagerExportVo).orElse(new ArrayList<>()).stream().map(source -> BeanUtil.convert(source, GManagerExportVo.class)).collect(Collectors.toList()); //副总List<AllAchievementExportVo> exportVosGroupLeader = Optional.ofNullable(leaderExports).orElse(new ArrayList<>()).stream().map(source -> BeanUtil.convert(source, AllAchievementExportVo.class)).collect(Collectors.toList());List<AllAchievementExportVo> exportVosStaff = Optional.ofNullable(TeamMemberExport).orElse(new ArrayList<>()).stream().map(source -> BeanUtil.convert(source, AllAchievementExportVo.class)).collect(Collectors.toList());List<MarketAchievementExportVo> exportVosFive = Optional.ofNullable(marketAchievementExport).orElse(new ArrayList<>()).stream().map(source -> BeanUtil.convert(source, MarketAchievementExportVo.class)).collect(Collectors.toList());// 排序List<AllAchievementExportVo> sortedAll = sortData(exportVos);List<GManagerExportVo> sortedGManager = sortDataGManager(exportVosGManager);List<AllAchievementExportVo> sortedGroupLeader = sortData(exportVosGroupLeader);List<AllAchievementExportVo> sortedStaff = sortData(exportVosStaff);List<MarketAchievementExportVo> sortedDetailed= sortDataDetailed(exportVosFive);try (ByteArrayOutputStream outputStream = new ByteArrayOutputStream()) {ExcelWriter writeWorkbook = EasyExcel.write(outputStream).registerWriteHandler(new LongestMatchColumnWidthStyleStrategy()).build();// 创建5个SheetWriteSheet writeSheetAll = EasyExcel.writerSheet("所有人排名").head(AllAchievementExportVo.class).build();writeWorkbook.write(sortedAll, writeSheetAll);WriteSheet writeSheetGManager = EasyExcel.writerSheet("营销副总排名").head(GManagerExportVo.class).build();writeWorkbook.write(sortedGManager, writeSheetGManager);WriteSheet writeSheetAllThree = EasyExcel.writerSheet("组长排名").head(AllAchievementExportVo.class).build();writeWorkbook.write(sortedGroupLeader, writeSheetAllThree);WriteSheet writeSheetFour = EasyExcel.writerSheet("组员排名").head(AllAchievementExportVo.class).build();writeWorkbook.write(sortedStaff, writeSheetFour);WriteSheet writeSheetDetailed = EasyExcel.writerSheet("业绩分配明细").head(MarketAchievementExportVo.class).build();writeWorkbook.write(sortedDetailed, writeSheetDetailed);writeWorkbook.finish();try (ByteArrayInputStream inputStream = new ByteArrayInputStream(outputStream.toByteArray())) {FileInfo fileInfo = whaleClientConfig.getWhalefsClient().upload(whaleClientConfig.getBucketName(), "tmp/" + "业绩分配" + winApprovalStartDateStr + "-" + winApprovalEndDateStr + ".xlsx", inputStream, true);return fileInfo.getUrl();}} catch (Exception e) {e.printStackTrace();log.error(String.format("业绩分配导出错误, 参数:[%s]", JSONObject.toJSONString(query)));log.error(String.format("业绩分配导出错误, 错误信息:[%s]", e.getMessage()));throw new BusinessException("导出Excel错误");}}

要注意导出类的实体Vo,对于一些Excel常用的注解，注解类的注释

java">@ApiModelProperty(value = "序号")@TableId(type = IdType.AUTO)@ExcelProperty(value = "序号",index = 0)private Integer index;

多余不展示字段

java">@ApiModelProperty(value = "上报通过开始日期")@DateTimeFormat("yyyy-MM-dd")@ExcelIgnoreprivate Date winApprovalStartDate;
