            //InetAddress address = InetAddress.getLocalHost();
            InetAddress address = InetAddress.getByName("192.168.46.53");

            /*
             * Get NetworkInterface for the current host and then read the
             * hardware address.
             */
            NetworkInterface ni = NetworkInterface.getByInetAddress(address);
            if (ni != null) {
                byte[] mac = ni.getHardwareAddress();
                if (mac != null) {
                    /*
                     * Extract each array of mac address and convert it to hexa with the
                     * following format 08-00-27-DC-4A-9E.
                     */
                    for (int i = 0; i < mac.length; i++) {
                        System.out.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : "");
                    }
                } else {
                    // Address doesn't exist or is not accessible.
                }
            } else {
                // Network Interface for the specified address is not found.
            }

以下是我实施的代码,它对我有用。此代码来自:Get mac address ip address in jsp java

守则如下:

    <script type="text/javascript" language="javascript">
       var x = this.getElementsByClassName('getDownloadLink')[0].href; //this is not working!
    </script>
