Java 如何从其他类读取conf.properties文件？

我是Selenium的初学者，我为阅读创建了一个名为

ReadPropertyFile

的类名。在这个类中，我编写了一个用于读取

config.properties

文件的代码。现在我有了一个主类，我想从中调用

ReadPropertyFile

类以及它们的活动，我可以从中读取

config.properties

文件

请帮助我如何执行此操作，以下是代码：

ReadPropertyFile.java：

public class ReadPropertyFile {

    public static void main(String[] arg)throws IOException{

        // Read configuration properties file

        String projdir = System.getProperty("user.dir");
        String propfilepath = projdir+"\\configuration\\"+"conf.properties";
        Properties p = new Properties();
        p.load(new FileInputStream(propfilepath ));

        String url  = p.getProperty("URL");
        System.out.println(url); // It is returning me a value corresponding to key "test"
        String driverFilePath = p.getProperty("DRIVER_FILE_PATH");
        System.out.println(driverFilePath);
        String testSuite  = p.getProperty("TEST_SUITE");
        System.out.println(testSuite);
    }
}

MainClass.java

public class MainClass {

    static Properties properties= new Properties();

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        ReadPropertyFile readConfigFile= new ReadPropertyFile();
    }
}

---

将配置读取器放入类方法中

而且一次只能使用“main”一次

  public class ReadPropertyFile{

           public void readFile(){

                // read config

---

如果此代码正在工作，请将其放入方法中

public class ReadPropertyFile {

 public Properties  loadPropertiess() throws IOException{

// Read configuration properties file

   String projdir = System.getProperty("user.dir");
   String propfilepath = projdir+"\\configuration\\"+"conf.properties";
   Properties p = new Properties();
 p.load(new FileInputStream(propfilepath ));

   String url  = p.getProperty("URL");
  System.out.println(url); // It is returning me a value corresponding to key "test"
  String driverFilePath = p.getProperty("DRIVER_FILE_PATH");
  System.out.println(driverFilePath);
  String testSuite  = p.getProperty("TEST_SUITE");
   System.out.println(testSuite);
   return p;
} }

然后在主类上调用此方法

public class MainClass {

  static Properties properties= null;

  public static void main(String[] args) throws Exception{
// TODO Auto-generated method stub

  ReadPropertyFile readConfigFile= new ReadPropertyFile();

   properties = readConfigFile.loadPropertiess();
   }
}
