Question

当我将数值传递到Excel工作表时，它会占用两倍，因此存在DataProvider Mismatch异常。如何处理此异常以及如何仅传递数值而不是双值？

以下是我的代码：

@DataProvider(name = "testdata")

public Object[][] TestDataFeed() throws Exception

{
    FileInputStream fis = new 

    FileInputStream("C:\\Users\\vidhya.r\\Desktop\\Testdata.xlsx");

    XSSFWorkbook wb = new XSSFWorkbook(fis);

    XSSFSheet sh1 = wb.getSheetAt(2);

    int numrow = sh1.getLastRowNum() + 1;

    int colnum = sh1.getRow(0).getLastCellNum();

    System.out.println("numrow ======= " + numrow);

    System.out.println("colnum ======= " + colnum);

    Object[][] data = new Object[numrow - 1][colnum];

    System.out.println("data.length ======= " + data.length);

    for (int i = 1; i < numrow; i++)

    {

        Row row = sh1.getRow(i);

        for (int j = 1; j < row.getLastCellNum(); j++)

        {
            int cellValue = sh1.getRow(i).getCell(j).getCellType();

            if (cellValue == Cell.CELL_TYPE_NUMERIC)

            {

                Object obj = 
                sh1.getRow(i).getCell(j).getNumericCellValue();

                data[i - 1][j-1] = obj;
                System.out.println("obj =num= " + obj);
            }

            else if (cellValue == Cell.CELL_TYPE_STRING)

            {

                Object obj = 
                sh1.getRow(i).getCell(j).getStringCellValue();

                data[i - 1][j-1] = obj;
                System.out.println("obj =str= " + obj);

            }
        }
    }
  return data;
  }

请帮我处理这个
