獲取本機所有IP java

有時候

InetAddress.getLocalHost().getHostAddress()

會因爲本機網絡環境發生變化出問題，用下面方法可以獲得本機所有IP。

EXample:

import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;
public class GetIPAddressOuterExample {
	/**
	 * @param args
	 * @throws SocketException 
	 */
	public static void main(String[] args) throws SocketException {
		// TODO Auto-generated method stub
		Enumeration<NetworkInterface> e = NetworkInterface.getNetworkInterfaces();
		while (e.hasMoreElements())
		{
			Enumeration<InetAddress> l = e.nextElement().getInetAddresses();
			while (l.hasMoreElements())
			{
				System.out.println(l.nextElement().getHostAddress());
			}
		}
	}
}

Result:
