我通过 /**

* @return
* @throws SocketException
*/
private static List<Inet4Address> getInet4Addresses() throws SocketException {
List<Inet4Address> ret = new ArrayList<Inet4Address>();
Enumeration<NetworkInterface> nets = NetworkInterface.getNetworkInterfaces();
for (NetworkInterface netint : Collections.list(nets)) {
Enumeration<InetAddress> inetAddresses = netint.getInetAddresses();
for (InetAddress inetAddress : Collections.list(inetAddresses)) {
if (inetAddress instanceof Inet4Address && !inetAddress.isLoopbackAddress()) {
ret.add((Inet4Address)inetAddress);
}
}
}
return ret;
}
/**

private static String getHost4Address() throws SocketException {
List<Inet4Address> inet4 = getInet4Addresses();
return !inet4.isEmpty()
