java - 如何获取系统数据并使我的应用程序针对操作系统独一无二

Question

我想知道如何获取我的应用程序安装的电脑的唯一标识符。我在here中关注了一些问题.但我无法利用它。请让我知道如何使用示例代码或任何有用的链接在 Java 中执行此操作。(至少如何在 Java 中获取系统详细信息)谢谢

不稳定的想法和不稳定的输出，请注意，您收到了正确的计算机和用户信息、PC 的唯一标识符以及更可靠的结果，返回硬件防火墙后面的 Intranet(而不是 Interner)中的计算机

问题:

• IP可以更改
• MAC 可以别名

Novell、AD 可以添加详细的用户信息，并且某些计算机(所有 HP/Compaq)不返回硬件配置

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);        
}
