Question

我想知道如何获取我的应用程序安装的PC的唯一标识符。我在here中提到了一些问题。但我无法使用它。请通过示例代码或任何有用的链接告诉我如何在Java中完成它。（至少如何在Java中获取系统详细信息）谢谢

Answer 1

您可以使用系统的mac地址，每个系统都有唯一的mac地址。

/*
* 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 {
        System.out.println("Address doesn't exist or is not accessible.");
        }
    } else {

        System.out.println("Network Interface for the specified address is not found.");

    }

不稳定输出的不稳定的想法，注意到你收到了正确的计算机＆amp;用户信息，PC的唯一标识符和更自信的结果返回HW FireWall后面的Intranet（非Interner）中的计算机

问题：

IP可以登陆
MAC可以Alliased

Novell，AD可以添加详细的UserInfo，而某些计算机（所有HP / Compaq）都不会返回硬件配置

private void getPcInfo() {
    Enumeration<?> interfaces = null;
    try {
        PcLogName = InetAddress.getLocalHost().getHostName();
        InetAddress local = InetAddress.getLocalHost();
        InetAddress[] all_local = InetAddress.getAllByName(local.getHostName());
        LinkedList<InetAddress> list = new LinkedList<InetAddress>();
        //System.out.println("PcLogName " + PcLogName);
        //System.out.println("PcLogName " + list);
        try {
            interfaces = NetworkInterface.getNetworkInterfaces();
            ////System.out.println("NetworkInterface " + interfaces);
        } catch (SocketException ex) {
            Logger.getLogger(GuiFrame.class.getName()).log(Level.SEVERE, null, ex);
        }
        while (interfaces.hasMoreElements()) {
            NetworkInterface card = (NetworkInterface) interfaces.nextElement();
            ////System.out.println("NetworkInterface NetCard " + card);
            Enumeration<?> addresses = card.getInetAddresses();
            ////System.out.println("NetCard Name " + addresses);
            if (addresses == null) {
                continue;
            }
            while (addresses.hasMoreElements()) {
                InetAddress address = (InetAddress) addresses.nextElement();
                list.add(address);
                //System.out.println("Add Address : " + address);
            }
        }
        //System.out.println("IP's Address " + list);
    } catch (UnknownHostException ex) {
        Logger.getLogger(GuiFrame.class.getName()).log(Level.SEVERE, null, ex);
    }
    PcLogUser = System.getProperty("user.name");
    //System.out.println("PcLogUser : " + PcLogUser);
    WinUser = System.getenv("USER");
    //System.out.println("WinUser : " + WinUser);
    WinDsn = System.getenv("USERDOMAIN");
    //System.out.println("WinDsn : " + WinDsn);
    WinUserName = System.getenv("USERNAME");
    //System.out.println("WinUserName : " + WinUserName);
    WinPath = System.getenv("USERPROFILE");
    //System.out.println("WinPath : " + WinPath);
    ComputerName = System.getenv("COMPUTERNAME");
    //System.out.println("ComputerName : " + ComputerName);
    PcInfo = System.getenv("System Model");
    //System.out.println("PcInfo : " + PcInfo);        
}

恕我直言，简单有效的方法是获取硬盘ID。在Windows上解析“dir”输出。这是稳定的，直到用户更换de Hard Drive并重新安装操作系统，但它并不完美。
