java中获取当前服务器的Ip地址的方法

publicstaticvoidmain(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();

   }

 }
