无法使用 java 从 selenium webdriver 中的 excel 表中获取数值

Question

我的 Java

public class Readexcel {
public void readfile(String filepath, String filename, String sheetname) throws IOException
{
    File file = new File(filepath+"\\"+filename);
    FileInputStream fis = new FileInputStream(file);

    // for creating .xlsx workbook
    Workbook wb = new XSSFWorkbook(fis);

    // for reading the sheet by its name
    Sheet sh = wb.getSheet(sheetname);

    //find the total rows in sheet

    int rowcount = sh.getLastRowNum()-sh.getFirstRowNum();

    // create a loop to create 

    for(int i=0;i<rowcount+1;i++)
    {
        Row row= sh.getRow(i);

        // create a loop to print cell values

        for(int j=0;j<row.getLastCellNum();j++)
        {
            Cell cell= row.getCell(j);
            switch (cell.getCellType()) {
            case Cell.CELL_TYPE_STRING:
                    System.out.print(row.getCell(j).getStringCellValue() + " ");
                    break;

            case Cell.CELL_TYPE_NUMERIC:
                    System.out.print(row.getCell(j).getNumericCellValue() + " ");
                    break;
            }
            System.out.print(row.getCell(j).getStringCellValue()+"||");

        }


    System.out.println();
    }


    }

   public static void main(String...strings) throws IOException
     {
         Readexcel re = new Readexcel();
         String filepath = "F://Excelsheet";
         re.readfile(filepath,"Book1.xlsx","Sheet1");
      }

}

通过使用上面的代码，我收到一个错误“无法从数字单元格获取文本值”。有什么帮助吗？我的输出也没有正确对齐。所有的字符串都显示一个下一个。输出应该像

Username Password
john     123
rambo    456    

但我得到的输出像

Username
password
john

在 // create a loop to print cell values 对此发表评论后更改你的 for 循环：

for (int j = 0; j < row.getLastCellNum(); j++) {
    Cell cell = row.getCell(j);
    switch (cell.getCellType()) {
    case Cell.CELL_TYPE_STRING:
            System.out.print(row.getCell(j).getStringCellValue() + " ");
            break;

    case Cell.CELL_TYPE_NUMERIC:
            System.out.print((int)row.getCell(j).getNumericCellValue() + " ");
            break;

            }

}

开关是识别单元格的类型。对于数字单元格，您必须使用 getNumericCellValue() 而不是 getStringCellValue()

对于第二个问题，使用System.out.print() 而不是System.out.println()，它用于打印双引号之间的内容并将打印光标移动到下一行。

编辑：

这就是我的 readFile() 函数的样子：

public void readfile(String filepath, String filename, String sheetname)    throws IOException {


    File file = new File(filepath+"\\"+filename);
    FileInputStream fis = new FileInputStream(file);

    // for creating .xlsx workbook
    Workbook wb = new XSSFWorkbook(fis);

    // for reading the sheet by its name
    Sheet sh = wb.getSheet(sheetname);

    // find the total rows in sheet

    int rowcount = sh.getLastRowNum() - sh.getFirstRowNum();

    // create a loop to create

    for (int i = 0; i < rowcount + 1; i++) {
        Row row = sh.getRow(i);

        // create a loop to print cell values

        for (int j = 0; j < row.getLastCellNum(); j++) {
            Cell cell = row.getCell(j);
            switch (cell.getCellType()) {
            case Cell.CELL_TYPE_STRING:
                System.out.print(row.getCell(j).getStringCellValue() + " ");
                break;

            case Cell.CELL_TYPE_NUMERIC:
                System.out.print((int)row.getCell(j).getNumericCellValue() + " ");
                break;

            }

        }

        System.out.println();
    }

}

将System.out.print(row.getCell(j).getNumericCellValue() + " "); 更改为 System.out.print((int)row.getCell(j).getNumericCellValue() + " "); 以防 Cell.CELL_TYPE_NUMERIC
