java - 我想动态更新 gui.properties 文件的键值对

Question

我正在研究 Selenium 自动化。我需要在运行时更新 GUI.properties 键值对。我尝试了以下代码，但没有反射(reflect)更改。

Properties p = new Properties();
    try {       
        p.load(PropertyMap.class.getResourceAsStream("/gui.properties"));
        p.setProperty(key, value);
        return p;   

        } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }       

在调用方法中，我是这样调用的

PropertyMap.setProperties("SoftwareLifecycleStage.Selectors", "Concept");

clickOnFieldIfValueIsNotNull(getSelectorsXPath(properties.getProperty("Myssi.SoftwareLifecycleStage.Selectors")), "LifecycleStageSelectors");

上面的方法clickonfieldifvalueisnotnull是一个通用方法，它只是通过xpath点击给定的元素，而getSelectorsXPath只是给出该元素的 xpath。

我也尝试了以下代码...

Properties p = new Properties();
   try {
        PropertiesConfiguration config = new PropertiesConfiguration("src/test/resources/gui.properties");          
        config.setProperty(key, value);         
        } catch (ConfigurationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
      }     

请帮助我吗？

更新:-

添加

Config.save(); is worked for me... But the problem I am facing is After saving the file, I have given Thread.sleep(2000); to just reflect the changes, But it is not picking up the changed values for the next lines. I tried removing thread.sleep, but the same repeating.... After the execution of test, I have checked the gui.properties, the corresponding values have changed...

是否需要调用config.save();最后的方法？

Properties p = new Properties();
try {
    PropertiesConfiguration config = new PropertiesConfiguration("src/test/resources/gui.properties");          
    config.setProperty(key, value);  
    // call save?
    config.save();
} catch (ConfigurationException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
