excel導入報錯：The supplied data appears to be in the Office 2007+ XML.

用以上語句導入excel的時候報錯：
信息: Request processing failed; nested exception is org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. POI only supports OLE2 Office documents

 

原因是：
HSSFWorkbook:是操作Excel2003以前（包括2003）的版本，擴展名是.xls
XSSFWorkbook:是操作Excel2007的版本，擴展名是.xlsx
