IP获取

1.获取window本地IP（排除虚拟路由）

/**
 * 获取window本机IP
 * @return
 */
public static String getWindowIP() {
    try {
        Enumeration allNetInterfaces = NetworkInterface
                .getNetworkInterfaces();
        while (allNetInterfaces.hasMoreElements()) {
            NetworkInterface netInterface = (NetworkInterface) allNetInterfaces
                    .nextElement();

            // 去除回环接口，子接口，未运行和接口
            if (netInterface.isLoopback() || netInterface.isVirtual()
                    || !netInterface.isUp()) {
                continue;
            }

            if (!netInterface.getDisplayName().contains("Intel")
                    && !netInterface.getDisplayName().contains("Realtek")) {
                continue;
            }
            Enumeration addresses = netInterface
                    .getInetAddresses();
            while (addresses.hasMoreElements()) {
                InetAddress ip = addresses.nextElement();
                if (ip != null) {
                    // ipv4
                    if (ip instanceof Inet4Address) {
                        return ip.getHostAddress();
                    }
                }
            }
            break;
        }
    } catch (SocketException e) {
        log.error(e.getMessage(),e);
    }
    return null;
}

2.获取linux的IP

   /**
     *  获取linux本机IP
     */
    public static String getLinuxIP(){
        InetAddress localHost = null;
        try {
            localHost = InetAddress.getLocalHost();
        } catch (UnknownHostException e) {
            log.error(e.getMessage(),e);
        }
        return localHost.getHostAddress();
    }
