public class Config {
    private static String CONFIG_FILE_PATH = "/config.properties";
    private static Config inst;

    }
    private void init(){
        System.out.println("init//////////");
        InputStream in=getClass().getResourceAsStream(CONFIG_FILE_PATH);
        Properties pro= new Properties();
        try {
            pro.load(in);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        ip=pro.getProperty("ip");
        port=Integer.parseInt(pro.getProperty("port"));
        
    }
    public String getIP(){
        return ip;
    }
    public int getPort(){
        return port;
    }
}

config.properties放在src根目录下
