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;





	}
