Properties文件在编写的时候没编写一个值的都要写一次key，这个可以利用excel表格来解决。
1.在工程目录下创建一个excel的表格，填写数据
2.创建excel类，构建一个返回值是Object[][]的方法，读取excel表格中的数据

public class excel{
    
       public static Object[][] readFromExcel_o(String dataFile,String sheetName,int rowNum) throws IOException {

        ArrayList<Object> list = new ArrayList<Object>();

        Object[][] data = null;

        //创建workbook
        File file = new File(dataFile);
        try {
            workbook = new HSSFWorkbook(new FileInputStream(file));
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 读取excel数据
        // 获得指定的excel表
        HSSFSheet sheet = workbook.getSheet(sheetName);
        // 获取表格的总行数
        int rowCount = sheet.getLastRowNum() + 1;
        // 获取表头的列数
        int columnCount = sheet.getRow(0).getLastCellNum();


//        将表格中的 值传到一个list中
        if(sheet!=null){
            for(int i=1;i<=rowCount-1;i++){
                for(int j=0;j<columnCount;j++){
                    HSSFRow row = sheet.getRow(i);
                    String concent = row.getCell(j).toString();
                    list.add(concent);
                }
            }
        }

        if (rowNum<=0||rowNum>=rowCount){
            data = new Object[rowCount-1][columnCount] ;
            int k=-1;
            for (int i=0;i<rowCount-1;i++){
                for (int j=0;j<columnCount;j++){
                    if (k<list.size()){
                        k++;
                    }
                    String concent = list.get(k).toString();
                    data[i][j]=list.get(k);
                }
            }
        }else {
            int k=-1;
            data = new Object[rowNum][columnCount];
            for (int i=0;i<rowNum-1;i++){
                for (int j=0;j<columnCount-1;j++){
                    if (k<list.size()){
                        data[i][j]=list.get(k);
                    }
                }
            }
        }
        workbook.close();
        return data;
    }

}

3.DataProvider中调用readFromExcel_o方法读取excel的值并返回值给DataProvider

public class DataPro {

//    成功登陆的用户名密码
    @DataProvider(name = "loginSuccess")
    public static Object[][] data() throws IOException {
        Object[][] data;
        String text = System.getProperty("user.dir");
        String file = text + "/taskdata_excel/danshang.xls";
        data = ExcelUtil.readFromExcel_o(file, "sheet1", 3);
        return data;
    }
}

4.创建测试类，利用DataProvider传入的值执行脚本

public class Login_Test {
    WebDriver driver;

    @Test(dataProvider = "loginSuccess",alwaysRun = true, dataProviderClass = DataPro.class)
    public void login(String account,String password) {
        driver = SeleniumDriver.openBrowser("firefox","http://www.epwk.us/");
        Action.click(LoginPage.loginButton);
//        输入账号密码登陆
        Action.sendkeys(LoginPage.account, account);
        Action.sendkeys(LoginPage.password, password);
        Action.click(LoginPage.submintButton);

    }
