java - 无法从 excel 单元格中获取数值

Question

public Object[][] dataProviderMethod() throws IOException {

    try {
        file = new FileInputStream(new File("/Users/nanthakumar/Documents/workspace/Myna_Admin/src/com/myna/testdata/login.xls"));
        workbook = new HSSFWorkbook(file);
        sheet = workbook.getSheetAt(0);
        row = sheet.getLastRowNum() + 1;
        col = sheet.getRow(0).getLastCellNum();
        data = new String[row][col];

        for (i = 0; i < row; i++) {
            rowvalue = sheet.getRow(i);
            for (j = 0; j < col; j++) {
                cellValue = rowvalue.getCell(j);
                data[i][j] = cellValue.getStringCellValue();
                System.out.println("The value is ----->" + data[i][j]);
            }

            workbook.close();
            file.close();
        }
    } catch (FileNotFoundException nana) {
        nana.printStackTrace();
    }



    return data;
}

这是我的代码，我尝试添加 getnumericalCellvalue() 而不是 getStringCellValue() 但这对我不起作用。

首先你要在模板excel中检查列是数字还是文本。当且仅当列是数字类型时你才能得到数值。所以改变模板excel并尝试
