List<AlertDailySummary> summaryList = alertMessageRecordService.selectSummaryForDaily("all"), startDate);
Assert.assertNotNull(summaryList);
String fileName = "D:\\12.xlsx";
ExcelWriter excelWriter = null;
try {
excelWriter = EasyExcel.write(fileName, AlertSummaryHeadData.class).build();
WriteSheet sheet = EasyExcel.writerSheet("模板").build();
excelWriter.write(summaryList, sheet);
