获取IPV4或IPV6地址

 1 public String getPodIp() {
 2     try {
 3         String ipButton = Application.getProperty("ipButton", "ipv4");
 4         Enumeration < NetworkInterface > networkInterfaces = NetworkInterface.getNetworkInterfaces();
 5         while (networkInterfaces.hasMoreElements()) {
 6             Enumeration < InetAddress > inetAddresses = networkInterfaces.nextElement().getInetAddresses();
 7             while (inetAddresses.hasMoreElements()) {
 8                 InetAddress inetAddress = inetAddresses.nextElement();
 9                 if ("ipv4".equals(ipButton)) {
10                     if (!inetAddress.isLoopbackAddress() 
11                         && inetAddress instanceof Inet4Address 
12                         && !StringUtils.contains(inetAddress.getHostAddress(), ":")) {
13                         return inetAddress.getHostAddress();
14                     }
15                 }
16                 if ("ipv6".equals(ipButton)) {
17                     if (!inetAddress.isLoopbackAddress() 
18                         && !inetAddress.isAnyLocalAddress() 
19                         && !inetAddress.isLinkLocalAddress() 
20                         && inetAddress instanceof Inet6Address) {
21                         String ip = inetAddress.getHostAddress();
22                         int index = ip.indexOf("%");
23                         if (index > 0) {
24                             ip = ip.substring(0, index);
25                         }
26                         return ip;
27                     }
28                 }
29             }
30         }
31     } catch (SocketException e) {
32         LOGGER.error("获取IP地址出现异常..:", e);
33     }
34     return "";
35 }

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。）

1 System.getProperty("server.port");
