先贴一下代码，代码出处：[https://blog.csdn.net/wangxihong\_123/article/details/80482725][https_blog.csdn.net_wangxihong_123_article_details_80482725]

public static String getLinuxLocalIp() {
            String ip = "";
            try {
                for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements(); ) {
                    NetworkInterface intf = en.nextElement();
                    String name = intf.getName();
                    if (!name.contains("docker") && !name.contains("lo")) {
                        // 不含有docker和lo
                        for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements(); ) {
                            InetAddress inAddress = enumIpAddr.nextElement();
                            if (!inAddress.isLoopbackAddress()) {
                                String ipaddress = inAddress.getHostAddress().toString();
                                if (!ipaddress.contains("::") && !ipaddress.contains("0:0:")
                                        && !ipaddress.contains("fe80")) {
                                    ip = ipaddress;
                                }
                            }
                        }
                    }
                }
            } catch (SocketException e) {
                System.out.println("获取ip失败");
                ip = "127.0.0.1";
            }
            return ip;
        }

代码测试在windows单网卡（台式机）的情况下可以获取到正确IP地址，多块网卡的情况下没办法获取到。

linux环境下正常获取ip（虚拟机测试结果）

贴一下我本机的网卡配置。机器为笔记本，系统为win10企业版1803版本
