場景

SpringBoot中使用POI實現Excel導入到數據庫（圖文教程已實踐）：

https://blog.csdn.net/BADAO_LIUMANG_QIZHI/article/details/88660466

在Excel導入到數據庫后進行格式驗證，如果有錯誤則將錯誤的Cell標紅然后驗證完成后

將標紅的Excel下載到客戶端。

實現

js中發送請求

//解析Excel操作 function parseExcel(){var url = "/wmsReceiveOrder/parseExcel";$.ajax({type: 'POST',url: url,cache: false,? //禁用緩存contentType: false,dataType: "json",processData:false,success: function (result) {//250則為驗證不通過則下載不正確的excelif(result.statusCode=="250"){alert(result.message)window.location.href="/wmsReceiveOrder/downloadMistakeExcel";}else{alert(result.message)if(result.statusCode=="200"){window.location.reload()}}}})return false; }

后臺解析Excel的方法

?@Description("解析Excel")@ResponseBody@RequestMapping("/parseExcel")@Transactionalpublic Map<String, Object> parseExcel(HttpServletRequest request) {return receiveOrderService.parseExcel(request);}
