java获取当前服务的IP和端口（tomcat）

最近遇到个需求，需要在代码中获取当前服务的内网ip和端口，废话不多说，直接上代码（都是Linux服务器，windows的没试过，可能会有所区别）

//获取内网ip
public static String getLocalIp() {
        try {
            for (Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces(); interfaces
                    .hasMoreElements();) {
                NetworkInterface networkInterface = interfaces.nextElement();
                if (networkInterface.isLoopback() || networkInterface.isVirtual() || !networkInterface.isUp()) {
                    continue;
                }
                Enumeration<InetAddress> addresses = networkInterface.getInetAddresses();
                if (addresses.hasMoreElements()) {
                    return addresses.nextElement().getHostAddress();
                }
            }
        }
        catch (SocketException e) {
            LoggerUtil.log(Level.INFO, "获取ip出现异常:{}", e.getMessage());
        }
        return null;
    }

    // 获取端口
    public static String getLocalPort() {
        try {
            MBeanServer server;
            if (MBeanServerFactory.findMBeanServer(null).size() > 0) {
                server = MBeanServerFactory.findMBeanServer(null).get(0);
            } else {
                return "";
            }
            Set<ObjectName> names = server.queryNames(new ObjectName("Catalina:type=Connector,*"),
                    Query.match(Query.attr("protocol"), Query.value("HTTP/1.1")));

            Iterator<ObjectName> iterator = names.iterator();
            if (iterator.hasNext()) {
                ObjectName name = iterator.next();
                return server.getAttribute(name, "port").toString();
            }
        }
        catch (Exception e) {
            LoggerUtil.log(Level.INFO, "获取port出现异常:{}", e.getMessage());
        }
        return "";
    }
