程式在本地沒問題，釋出到linux上報錯，百度了一下是ip獲取方法InetAddress.getLocalHost().getHostAddress()不相容linux，網上提供一種解決方案是修改linux伺服器配置，我試了一下，沒用，於是採用另一種方案，如下：

    private static String getLinuxLocalIp() throws SocketException {
        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")) {
                    for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
                        InetAddress inetAddress = enumIpAddr.nextElement();
                        if (!inetAddress.isLoopbackAddress()) {
                            String ipaddress = inetAddress.getHostAddress().toString();
                            if
 
 (!ipaddress.contains("::") && !ipaddress.contains("0:0:") && !ipaddress.contains("fe80")) {
                                ip = ipaddress;
                            }
                        }
                    }
                }
            }
        } catch (SocketException ex) {
            System.out.println("獲取ip地址異常"
 
);
            ip = "127.0.0.1";
            ex.printStackTrace();
        }
        return ip;
    }

public static String getLocalIP() throws UnknownHostException, SocketException {
        if (isWindowsOS()) {
            return InetAddress.getLocalHost().getHostAddress();
        } else {
            return getLinuxLocalIp();
        }
    }
