用于生成机器码

感觉用mac不靠谱，因为mac能改，

（除CPU序列号外，还可以获得主板序列号。）

 

public static void main(String[] args) {
	// TODO Auto-generated method stub
	try {
		long start = System.currentTimeMillis();
		Process process = Runtime.getRuntime().exec(
		new String[] { "wmic", "cpu", "get", "ProcessorId" });
		process.getOutputStream().close();
		Scanner sc = new Scanner(process.getInputStream());
		String property = sc.next();
		String serial = sc.next();
		System.out.println(property + ": " + serial);
		System.out.println("time:" + (System.currentTimeMillis() - start));
	} catch (IOException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}

}

 

ProcessorId: BFEBFBFF00030***

time:291

 

再用MD5加密下就成机器码了，不加密也行。
