获取IPV4或IPV6地址

public String getPodIp() {
    try {
        String ipButton = Application.getProperty("ipButton", "ipv4");
        Enumeration < NetworkInterface > networkInterfaces = NetworkInterface.getNetworkInterfaces();
        while (networkInterfaces.hasMoreElements()) {
            Enumeration < InetAddress > inetAddresses = networkInterfaces.nextElement().getInetAddresses();
            while (inetAddresses.hasMoreElements()) {
                InetAddress inetAddress = inetAddresses.nextElement();
                if ("ipv4".equals(ipButton)) {
                    if (!inetAddress.isLoopbackAddress() 
                        && inetAddress instanceof Inet4Address 
                        && !StringUtils.contains(inetAddress.getHostAddress(), ":")) {
                        return inetAddress.getHostAddress();
                    }
                }
                if ("ipv6".equals(ipButton)) {
                    if (!inetAddress.isLoopbackAddress() 
                        && !inetAddress.isAnyLocalAddress() 
                        && !inetAddress.isLinkLocalAddress() 
                        && inetAddress instanceof Inet6Address) {
                        String ip = inetAddress.getHostAddress();
                        int index = ip.indexOf("%");
                        if (index > 0) {
                            ip = ip.substring(0, index);
                        }
                        return ip;
                    }
                }
            }
        }
    } catch (SocketException e) {
        LOGGER.error("获取IP地址出现异常..:", e);
    }
    return "";
}

1. 上述代码可在虚机或容器环境下获取主机ip或pod ip
2. 根据配置需要获取ipv4或ipv6地址（需要提前知道系统配置的是ipv4或ipv6地址）

如果有获取服务端口需要可通过下面方式获取：（这种方式适用springboot项目。如果是容器环境，要求通过环境变量设置了server.port才能获取的到。）

System.getProperty("server.port");
