java 中 poi解析Excel文件版本问题解决办法

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)”

try{ //将文件的输入流转换成Workbook Workbook wb = WorkbookFactory.create(numFile.getInputStream()); //获得第一个工作表 Sheet sheet = wb.getSheetAt(0); //获得第一行 Row row = sheet.getRow(0); //获得第一行的第一列 Cell cell = row.getCell(0);}catch (Exception e){ e.printStackTrace();}
