拿局域网IP一般用在tcp通讯或udp通讯上，下次再整理下这类通讯的框架

上代码

/** * 网络工具 * 获得局域网IP地址 * @author  dlong * created at 2019/3/8 2:46 PM */public class NetworkUtils {    /**     * 获取内网IP地址     * @return     * @throws SocketException     */    public static String getLocalIPAddress() throws SocketException {        for(Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();){            NetworkInterface intf = en.nextElement();            for(Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();){                InetAddress inetAddress = enumIpAddr.nextElement();                if(!inetAddress.isLoopbackAddress() && (inetAddress instanceof Inet4Address)){                    return inetAddress.getHostAddress().toString();                }            }        }        return "null";    }}

kotlin版

import java.net.Inet4Addressimport java.net.InetAddressimport java.net.NetworkInterfaceimport java.util.*/** * @author D10NG * @date on 2019-12-10 14:37 */object NetUtils {    /**     * 获取内网IP地址     */    val localIPAddress: String        get() {            val en: Enumeration<NetworkInterface> = NetworkInterface.getNetworkInterfaces()            while (en.hasMoreElements()) {                val intf: NetworkInterface = en.nextElement()                val enumIpAddr: Enumeration<InetAddress> = intf.inetAddresses                while (enumIpAddr.hasMoreElements()) {                    val inetAddress: InetAddress = enumIpAddr.nextElement()                    if (!inetAddress.isLoopbackAddress && inetAddress is Inet4Address) {                        return inetAddress.hostAddress.toString()                    }                }            }            return "null"        }}
