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)

缘由是：
HSSFWorkbook:是操做Excel2003之前（包括2003）的版本，扩展名是.xls 
XSSFWorkbook:是操做Excel2007的版本，扩展名是.xlsx

 <!--处理2003 excel-->
