用JAVA获取服务器MAC地址

最近做软件注册这块需要获取计算机的唯一标识符,能唯一识符的可以有CPU型号,硬盘序列号和网卡序列号,这里我介绍一下获取MAC

import java.io.*;
import java.util.*;
public class mac{
public static void main(String[] args)
        {        
        System.out.println(getMacOnWindow());
        }
private static String getMacOnWindow() {
        String s = "";
        try {
            String s1 = "ipconfig /all";
            Process process = Runtime.getRuntime().exec(s1);
            BufferedReader bufferedreader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String nextLine;
            for (String line = bufferedreader.readLine(); line != null; line = nextLine) {
                nextLine = bufferedreader.readLine();
                if (line.indexOf("Physical Address") <= 0) {
                    continue;
                }
                int i = line.indexOf("Physical Address") + 36;
                s = line.substring(i);
                break;
            }
            bufferedreader.close();
            process.waitFor();
        } catch (Exception exception) {
            s = "";
        }
        return s.trim();
    }
}
 

希望对大家有用
