You need to call a different part of POI to process this data (eg XSSF instead of HSSF)的解决方法

【现象】

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)

【解决方法】

FileInputStream inps = new FileInputStream(System.getProperty("user.dir")+"\\运费.xlsx");
//读取工作簿
HSSFWorkbook workBook = new HSSFWorkbook(inps);
//读取工作表
HSSFSheet sheet = workBook.getSheetAt(0);

修改为：

 

FileInputStream inps = new FileInputStream(System.getProperty("user.dir")+"\\运费.xlsx");
//读取工作簿
XSSFWorkbook workBook = new XSSFWorkbook(inps);
//读取工作表
XSSFSheet sheet = workBook.getSheetAt(0);
