java中获取当前服务器的Ip地址的方法

public static void main(String[] args) {  　　try {       InetAddress address = InetAddress.getLocalHost();//获取的是本地的IP地址 //PC-20140317PXKX/192.168.0.121       String hostAddress = address.getHostAddress());//192.168.0.121             InetAddress address1 = InetAddress.getByName("www.wodexiangce.cn");//获取的是该网站的ip地址，比如我们所有的请求都通过nginx的，所以这里获取到的其实是nginx服务器的IP地        String hostAddress1 = address1.getHostAddress());//124.237.121.122        InetAddress[] addresses = InetAddress.getAllByName("www.baidu.com");//根据主机名返回其可能的所有InetAddress对象        for(InetAddress addr:addresses){        System.out.println(addr);//www.baidu.com/14.215.177.38        //www.baidu.com/14.215.177.37       }     } catch (UnknownHostException e) {        e.printStackTrace();   }  }
