使用Java获取服务器IP地址
public class NetworkInterfaceUtil {
private static List<NetworkInterface> getInterfaces() throws SocketException {
return Collections.list(NetworkInterface.getNetworkInterfaces());
}
private static List<NetworkInterface> getNonLoopBackInterfaces() throws SocketException {
return getInterfaces().stream()
.filter(i -> Unchecked.supplier(() -> !i.isLoopback()).get())
.collect(toList());
}
public static List<String> getIp4Addresses() throws SocketException {
final List<NetworkInterface> is = getNonLoopBackInterfaces();
return is.stream().flatMap(i -> {
final Enumeration<InetAddress> addresses = i.getInetAddresses();
final Builder<String> builder = Stream.builder();
while (addresses.hasMoreElements()) {
final InetAddress ip = addresses.nextElement();
if (!ip.isLoopbackAddress()) {
if (ip.getHostAddress().equalsIgnoreCase("127.0.0.1")) {
continue;
}
if (ip instanceof Inet6Address) {
continue;
}
if (ip instanceof Inet4Address) {
builder.add(ip.getHostAddress());
}
}
}
return builder.build();
}).collect(toList());
}
}
