使用easyexcel导出excel文件

这里是导出一个excel文件，里面有两个sheet
分别是税赋预测表和发票汇总表

controller层

 @requestMapping(value = "/exportExcel/taxForecast", method = Method.GET)
    public Result exportExcel(String uid, String accountCodeList, Date startDate, Date endDate, HttpServletResponse response) {
        log.info("帐套查询参数{},开始时间{},结束时间{},uid:{}",, accountCodeList, startDate, endDate, uid);
        try {
            List taxFore = iTaxForeCast.getTaxFore(accountCodeList, uid, startDate, endDate);
            getVO(taxFore);
            stripTrailingZeros(taxFore);
            List taxForeEOList = new ArrayList<>();
            List invoiceTaxForeEOS = new ArrayList<>();
            taxFore.forEach(taxForeDTO -> {
                InvoiceTaxForeEO invoiceTaxForeEO = new InvoiceTaxForeEO();
                BeanCopyUtils.copy(taxForeDTO, invoiceTaxForeEO);
                invoiceTaxForeEOS.add(invoiceTaxForeEO);
                TaxForeEO taxForeEO = new TaxForeEO();
                BeanCopyUtils.copy(taxForeDTO, taxForeEO);
                taxForeEOList.add(taxForeEO);
            });
            Map> map = new HashMap<>();
            map.put("税赋预测表", taxForeEOList);
            map.put("发票汇总表", invoiceTaxForeEOS);
            EasyExcelUtils.createExcelStreamMutilByEaysExcel(response, map, ExcelTypeEnum.XLSX);
        } catch (Exception e) {
            e.printStackTrace();
            return Result.fail("500", "导出失败");
        }
        return Result.success("导出成功");
    }
