java 获取linux mac_Linux系统java如何获取硬件唯一信息，比如MAC地址和CPU?

可以使用Java的相关API来获取Linux/Mac系统的硬件唯一信息，包括MAC地址和CPU。

获取MAC地址：
可以使用Java的NetworkInterface类来获取MAC地址，示例代码如下：

import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;

public class MacAddressUtil {
    public static void main(String[] args) {
        try {
            Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
            while (interfaces.hasMoreElements()) {
                NetworkInterface ni = interfaces.nextElement();
                byte[] mac = ni.getHardwareAddress();
                if (mac != null) {
                    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());
                }
            }
        } catch (SocketException e) {
            e.printStackTrace();
        }
    }
}

获取CPU信息：
可以使用Java的Runtime类和Process类来执行Linux/Mac系统的命令，获取CPU信息，示例代码如下：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class CpuInfoUtil {
    public static void main(String[] args) {
        String os = System.getProperty("os.name").toLowerCase();
        String[] cmd = {"/bin/sh", "-c", ""};
        if (os.contains("linux")) {
            cmd[2] = "cat /proc/cpuinfo | grep 'model name' | uniq";
        } else if (os.contains("mac")) {
            cmd[2] = "sysctl -n machdep.cpu.brand_string";
        }
        try {
            Process process = Runtime.getRuntime().exec(cmd);
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line = null;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
            reader.close();
            process.waitFor();
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}

以上代码仅供参考，具体实现需要根据实际情况进行调整。
