如何使用Java 5获取主机mac地址？ [英] How do I get the hosts mac address using Java 5?

问题描述

我知道您可以使用 java.net.NetworkInterface-> getHardwareAddress（）在Java 6中执行此操作。但是我部署的环境仅限于Java 5.

I know you can do this with Java 6 using java.net.NetworkInterface->getHardwareAddress(). But the environment I am deploying on is restricted to Java 5.

有人知道如何在Java 5或更早版本中执行此操作吗？非常感谢。

Does anyone know how to do this in Java 5 or earlier? Many thanks.

推荐答案

Java 5中的标准方法是启动本机进程来运行 ipconfig 或 ifconfig 并解析 OutputStream 以获得答案。

The standard way in Java 5 was to start a native process to run ipconfig or ifconfig and parse the OutputStream to get your answer.

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);
        }
    }
}
