上传Excel解析时报错：Convert excel format exception.You can try specifying the ‘excelType‘ yourself

原因是：因为在通过file获取的流类型，在EasyExcel.read读的时候，采用的同一个流，会导致excel类型出错。

解决方法：重新创建一个excel流，与获取文件流类型的流区别使用 

InputStream inputStream = multipartfile.getInputStream();
String fileType = CheckFileFormatUtil.getFileType(multipartfile.getInputStream());
