org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML.
You are calling the part of POI that deals with OLE2 Office Documents. You need to call a different part of POI to process this data (eg XSSF instead of HSSF)
原因是：
HSSFWorkbook:是操作Excel2003以前（包括2003）的版本，扩展名是.xls
XSSFWorkbook:是操作Excel2007的版本，扩展名是.xlsx
<!--处理2003 excel-->
