篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了用poi导入excel文件时，导入文本会出现小数点怎么解决。相关的知识，希望对你有一定的参考价值。
例如：excel行 2006 1 234 。在excel 中已设置列格式为文本。但读入后输出。为：2006.0 1.0 234.0如果在2006后面加上 年 即 2006年输出 （2006年） 就没事。
参考技术A poi是什么软件呢？是否可以在poi里面设置呢？你可以试试，在数字后面加空格，看看什么效果。
空格可以是半角的，也可以试试全角的。本回答被提问者采纳
SpringBoot+POI实现导入Excel时验证并返回错误Cell标红的文件
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
@Description("解析Excel")
@ResponseBody
@RequestMapping("/parseExcel")
@Transactional
public Map<String, Object> parseExcel(HttpServletRequest request)
return receiveOrderService.parseExcel(request);
serviceImpl
