篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了SpringBoot+POI实现导入Excel时验证并返回错误Cell标红的文件相关的知识，希望对你有一定的参考价值。
场景
SpringBoot中使用POI实现Excel导入到数据库（图文教程已实践）：
在Excel导入到数据库后进行格式验证，如果有错误则将错误的Cell标红然后验证完成后
将标红的Excel下载到客户端。
实现
js中发送请求
//解析Excel操作
function parseExcel()
var url = "/wmsReceiveOrder/parseExcel";
$.ajax(
type: POST,
url: url,
cache: false, //禁用缓存
contentType: false,
dataType: "json",
processData:false,
success: function (result)
//250则为验证不通过则下载不正确的excel
if(result.statusCode=="250")
alert(result.message)
window.location.href="/wmsReceiveOrder/downloadMistakeExcel";
else
alert(result.message)
if(result.statusCode=="200")
window.location.reload()
)
return false;
后台解析Excel的方法

@ResponseBody
@RequestMapping("/parseExcel")
