Java 5中的标准方法是启动一个本机进程来运行ipconfig或ifconfig解析OutputStream以获得您的答案。

例如：

private String getMacAddress() throws IOException {
    String command = “ipconfig /all”;
    Process pid = Runtime.getRuntime().exec(command);
    BufferedReader in = new BufferedReader(new InputStreamReader(pid.getInputStream()));
    Pattern p = Pattern.compile(”.*Physical Address.*: (.*)”);
    while (true) {
        String line = in.readLine();
        if (line == null)
            break;
        Matcher m = p.matcher(line);
        if (m.matches()) {
            return m.group(1);
        }
    }
}
