端口监控信息

netstat -nlptu | grep 8080

 一、 0.0.0.0:8080  代表8080端口，对内网和外网都是开放的

tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      123941/java   

二、查看网卡的代码：

/**
 * @date 2018/12/06 14:07:22
 * @desc 网卡打印
 */
public class PrintNetwork {
    private static Logger logger = LoggerFactory.getLogger(PrintNetwork.class);

    public static void main(String[] args) throws SocketException {
        Enumeration<NetworkInterface> obj = NetworkInterface.getNetworkInterfaces();
        while (obj.hasMoreElements()) {
            NetworkInterface networkInterface = (NetworkInterface) obj.nextElement();
            System.out.println(networkInterface.getName() + "  /  " + networkInterface.getDisplayName() + " / " + getInetAddress(networkInterface));
            System.out.println("\n");

        }
    }

    private static String getInetAddress(NetworkInterface nt) {
        Enumeration<InetAddress> inetAddresses = nt.getInetAddresses();
        while (inetAddresses.hasMoreElements()) {
            InetAddress inetAddress = inetAddresses.nextElement();
            // IPV4
            if (inetAddress != null && inetAddress instanceof Inet4Address) {
                return inetAddress.getHostAddress();
            }
        }
        return null;
    }
}
