java获取本机IP地址，非127.0.0.1

综合了网上找的代码，整理的，Windows和Linux都可以用。

	private static String getHostIp(){



		try{



			Enumeration<NetworkInterface> allNetInterfaces = NetworkInterface.getNetworkInterfaces();



			while (allNetInterfaces.hasMoreElements()){



				NetworkInterface netInterface = (NetworkInterface) allNetInterfaces.nextElement();



				Enumeration<InetAddress> addresses = netInterface.getInetAddresses();



				while (addresses.hasMoreElements()){



					InetAddress ip = (InetAddress) addresses.nextElement();



					if (ip != null 



							&& ip instanceof Inet4Address



                    		&& !ip.isLoopbackAddress() //loopback地址即本机地址，IPv4的loopback范围是127.0.0.0 ~ 127.255.255.255




                    		&& ip.getHostAddress().indexOf(":")==-1){



						System.out.println("本机的IP = " + ip.getHostAddress());



						return ip.getHostAddress();



					} 



				}



			}



		}catch(Exception e){



			e.printStackTrace();



		}



		return null;



	}
