java 如何获取本机所有ip地址呢？

实现思路:
    使用NetworkInterface.getNetworkInterfaces()方法
	 即可获取本机所有NetworkInterface

获取本机所有ip信息的方法分享

public static list<String> getLocalIPList() {
    List<String> ipList = new ArrayList<String>();
    try {
        Enumeration<NetworkInterface> networkInterfaces = NetworkInterface.getNetworkInterfaces();
        NetworkInterface networkInterface;
        Enumeration<InetAddress> inetAddresses;
        InetAddress inetAddress;
        String ip;
        while (networkInterfaces.hasMoreElements()) {
            networkInterface = networkInterfaces.nextElement();
            inetAddresses = networkInterface.getInetAddresses();
            while (inetAddresses.hasMoreElements()) {
                inetAddress = inetAddresses.nextElement();
                if (inetAddress != null && inetAddress instanceof Inet4Address) { // IPV4
                    ip = inetAddress.getHostAddress();
                    ipList.add(ip);
                }
            }
        }
    } catch (SocketException e) {
        e.printStackTrace();
    }
    return ipList;
}
