Exception in thread "main" 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) at org.apache.poi.poifs.storage.HeaderBlock.<init>(HeaderBlock.java:126) at org.apache.poi.poifs.storage.HeaderBlock.<init>(HeaderBlock.java:113) at org.apache.poi.poifs.filesystem.NPOIFSFileSystem.<init>(NPOIFSFileSystem.java:301) at org.apache.poi.hssf.usermodel.HSSFWorkbook.<init>(HSSFWorkbook.java:413) at org.apache.poi.hssf.usermodel.HSSFWorkbook.<init>(HSSFWorkbook.java:394) at com.demo.poi.PoiReadExcel.main(PoiReadExcel.java:26)
解决：Excel版本不对，用XSS代替HSSF
