当使用Apache POI库时，无法读取一行中的所有单元格值

Question

我在迭代一行中的所有单元时遇到问题，我能够正确读取前4个单元格，并将所有单元格都作为空值休息。任何帮助表示赞赏 //下面是我使用

InputStream is = new FileInputStream(new File(fileName)); 
    Workbook workbook = new XSSFWorkbook(is); 
    int numberOfSheets = workbook.getNumberOfSheets(); 
    for (int i = 0; i < numberOfSheets; i++) { 
     Sheet sheet = workbook.getSheetAt(i); 
     String name = sheet.getSheetName(); 
     if (name.equals(sheetName)) { 
     Iterator<Row> rowItr = sheet.rowIterator(); 
     while (rowItr.hasNext()) { 
      Row eachRow = rowItr.next(); 
      QuestionObjBuilder builder = new QuestionObjBuilder(); 
      Iterator<Cell> cellItr = eachRow.cellIterator(); 
      int index = 1; 
      while (cellItr.hasNext()) { 
      Cell eachCell = cellItr.next(); 
      int cellType = eachCell.getCellType(); 
      String label = ""; 
      if (cellType == Cell.CELL_TYPE_STRING) { 
       label = eachCell.getStringCellValue(); 
      } else if (cellType == Cell.CELL_TYPE_NUMERIC) { 
       int value = (int) eachCell.getNumericCellValue(); 
       label = String.valueOf(value); 
      } 
      builder = builder.set(index, label); 
      index++; 
      if (index > 10) { 
       break; 
      } 
      } 
     } 
     } 

    } 
    workbook.close();

如果你的目标是从读取Excel的所有单元格，你可以使用此代码的代码，

FileInputStream fileInputStream = new FileInputStream(fileName); 
     HSSFWorkbook workbook = new HSSFWorkbook(fileInputStream); 
     HSSFSheet worksheet = workbook.getSheet(sheetName); 

     Iterator<Row> it = worksheet.rowIterator(); 
     while(it.hasNext()){ 
      HSSFRow r = (HSSFRow) it.next(); 
      Iterator<Cell> it1=r.cellIterator(); 
      while(it1.hasNext()){ 
       HSSFCell cell = (HSSFCell)it1.next(); 
       System.out.println("Row: "+cell.getRowIndex()+" ,Column: "+cell.getColumnIndex()); 
       System.out.println(cell); 
      } 
      System.out.println(); 
     } 

    } catch (FileNotFoundException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    }
