linux 下获得ip地址方法

    最近将一个windows下的小项目放到linux下，一直出问题，主要是因为在windows下和在linux下或得ip地址的方法不一样：
    在linux获得ip地址方法如下：
      

import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;

public class NetworkInfo {

    public static void main(String[] args) throws SocketException {
        InetAddress local;
        for (Enumeration<NetworkInterface> i = NetworkInterface
                .getNetworkInterfaces(); i.hasMoreElements();) {
            NetworkInterface ni = i.nextElement();
            for (Enumeration<InetAddress> j = ni.getInetAddresses(); j
                    .hasMoreElements();) {
                local = j.nextElement();

                if (local.isSiteLocalAddress() && !local.isLoopbackAddress()
                        && (local.getHostAddress().indexOf(":") == -1)) {
                    System.out.println(local.getHostAddress());
                }
            }
        }
    }
}
