【Vesta发号器源码】IpUtils

Vesta发号器源码解析——IpUtils

一个跟IP相关的工具类,主要是两个方法

    //读取主机IP
    public static String getHostIp() {
        String ip = null;
        try {
            Enumeration en = NetworkInterface
                    .getNetworkInterfaces();
            while (en.hasMoreElements()) {
                NetworkInterface intf = (NetworkInterface) en.nextElement();
                Enumeration enumIpAddr = intf.getInetAddresses();
                while (enumIpAddr.hasMoreElements()) {
                    InetAddress inetAddress = (InetAddress) enumIpAddr
                            .nextElement();
                    if (!inetAddress.isLoopbackAddress()
                            && !inetAddress.isLinkLocalAddress()
                            && inetAddress.isSiteLocalAddress()) {
                        ip = inetAddress.getHostAddress();
                    }
                }
            }
        } catch (SocketException e) {
            log.error("Fail to get IP address.", e);
        }
        return ip;
    }

    //读取主机名字
    public static String getHostName() {
        String hostName = null;
        try {
            Enumeration en = NetworkInterface
                    .getNetworkInterfaces();
            while (en.hasMoreElements()) {
                NetworkInterface intf = (NetworkInterface) en.nextElement();
                Enumeration enumIpAddr = intf.getInetAddresses();
                while (enumIpAddr.hasMoreElements()) {
                    InetAddress inetAddress = (InetAddress) enumIpAddr
                            .nextElement();
                    if (!inetAddress.isLoopbackAddress()
                            && !inetAddress.isLinkLocalAddress()
                            && inetAddress.isSiteLocalAddress()) {
                        hostName = inetAddress.getHostName();
                    }
                }
            }
        } catch (SocketException e) {
            log.error("Fail to get host name.", e);
        }
        return hostName;
