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

public String export(MarketReceiveVo query) {
        Date winApprovalStartDate = query.getWinApprovalStartDate();
        Date winApprovalEndDate = query.getWinApprovalEndDate();

        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);

        try (ByteArrayOutputStream outputStream = new ByteArrayOutputStream()) {
            ExcelWriter writeWorkbook = EasyExcel.write(outputStream).registerWriteHandler(new LongestMatchColumnWidthStyleStrategy()).build();

            // 创建5个Sheet
            WriteSheet 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(sortedGroupLeader, writeSheetAllThree);

            WriteSheet writeSheetFour = EasyExcel.writerSheet("组员排名").head(AllAchievementExportVo.class).build();
            writeWorkbook.write(sortedStaff, writeSheetFour);

                        .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 复制代码

@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 复制代码

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