JAVA获取本机IP地址

一、windows操作系统下主机IP地址
try
{ 
        System.out.println("本机的IP = " + InetAddress.getLocalHost());
} catch (UnknownHostException e)
{ 
        e.printStackTrace();
}

二、linux操作系统下主机IP地址
Enumeration allNetInterfaces = NetworkInterface.getNetworkInterfaces();
InetAddress ip = null;
while (allNetInterfaces.hasMoreElements())
{
        NetworkInterface netInterface = (NetworkInterface) allNetInterfaces.nextElement();
        System.out.println(netInterface.getName());
        Enumeration addresses = netInterface.getInetAddresses();
        while (addresses.hasMoreElements())
        {
                ip = (InetAddress) addresses.nextElement();
                if (ip != null && ip instanceof Inet4Address)
                {
                        System.out.println("本机的IP = " + ip.getHostAddress());
                } 
        }
}
