如何从集成网络适配器获取 mac 地址

Question

许多主板都集成了网络适配器。如果存在，我需要从该设备获取 mac 地址。来自网络适配器：

private void getMacFromInetAddress(){
    try {

            Enumeration<NetworkInterface> networks = NetworkInterface.getNetworkInterfaces();
            while (networks.hasMoreElements()) {
                NetworkInterface network = networks.nextElement();
                byte[] mac = network.getHardwareAddress();

                if (mac != null) {
                    System.out.print("Current MAC address : ");

                    StringBuilder sb = new StringBuilder();
                    for (int i = 0; i < mac.length; i++) {
                        sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
                    }
                }
           }
        } catch (UnknownHostException | SocketException e) {
            System.out.println(e.getLocalizedMessage());
        }
}

如何从这段代码中指定集成网络适配器的名称？

Answer 1

使用 UUID 进行一些更改

第一次运行s，生成一个唯一的 UUID 并将其保存在本地存储中。从第 2 次开始使用从第 1 次运行保存的 UUID。

How to get mac address from device?

没有通过 Java 从系统中获取 mac address 的直接方法。但是你可以

要在计算机上获取 mac 个地址，只需运行命令 getmac 即可获取 mac 个地址。

使用ipconfig命令来处理。
使用 nbtstat 命令检索远程计算机的 mac 地址。
运行 getmac 和 getmac /s remote_computer /u username /p password 命令检索远程计算机的 mac 地址。

Get mac address from command line

但是通过Java你需要使用Java exec system with Java ProcessBuilder and Process

例如：

ProcessBuilder pb = new ProcessBuilder("getmac");
//Map<String, String> env = pb.environment(); //set env
pb.directory("C\");
Process p = pb.start();

或

// build my command as a list of strings
//@@@ For Unix/Linux
List<String> command = new ArrayList<String>();
command.add("getmac");

// execute my command
SystemCommandExecutor commandExecutor = new SystemCommandExecutor(command);
int result = commandExecutor.executeCommand();

然后通过读取输出：

// get the output from the command
StringBuilder stdout = commandExecutor.getStandardOutputFromCommand();
StringBuilder stderr = commandExecutor.getStandardErrorFromCommand();

// print the output from the command
System.out.println("STDOUT");
System.out.println(stdout);
System.out.println("STDERR");
System.out.println(stderr);

ProcessBuilder and Process Code

Note: 你的 java application 需要 administrative permission during execution.

Answer 3

InetAddress ip = InetAddress.getLocalHost();
System.out.println("Current IP address : " + ip.getHostAddress());

NetworkInterface network = NetworkInterface.getByInetAddress(ip);

byte[] mac = network.getHardwareAddress();

System.out.print("Current MAC address : ");

StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++) {
    sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
}
System.out.println(sb.toString());

要获取硬件信息，您可以使用 wmic 命令，例如 wmic cpu 获取 ProcessorId

 Process p = Runtime.getRuntime().exec("wmic cpu get ProcessorId");
            String procesSerial=
                    new BufferedReader
                            (new InputStreamReader(p.getInputStream())).[ReadSecondLine];

和 BIOS

wmic bios 获取序列号

 Process p = Runtime.getRuntime().exec("wmic bios get SerialNumber");

Answer 4

我建议您查看 oshi library 以获取系统 OS/hardware 信息。

查看 test case 示例。
