基于java如何读取并引用自定义配置文件？

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

public class MyConfig {
  public static Properties myProp = new Properties();
  public static InputStream myResource = MyConfig.class.getResourceAsStream("/myConfig.properties");
  static {
    try {
      myProp.load(myResource);
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
  public String getMyConf(String props) {
    return myProp.getProperty(props);
  }
  
  public static void main(String[] args) {
    final MyConfig myConfig = new MyConfig();
    System.out.println(myConfig.getMyConf("master_ip"));
  }
}
