远程ip是 192.168.1.28

public class GetMacByIp {
    public static void main(String[] args) throws UnknownHostException, SocketException {
        String ip = "192.168.1.28";
        String localMac = getLocalMac(ip);
        System.out.println(localMac);
    }
    public static String getLocalMac(String ipAddress){
        String str = "";
        String macAddress = "";
            // 获取非本地IP的MAC地址
            try {
                System.out.println(ipAddress);
                Process p = Runtime.getRuntime()
                        .exec("nbtstat -A " + ipAddress);
                System.out.println("===process==" + p);
                InputStreamReader ir = new InputStreamReader(p.getInputStream());
                BufferedReader br = new BufferedReader(ir);
                while ((str = br.readLine()) != null) {
                    if (str.indexOf("MAC") > 1) {
                        macAddress = str.substring(str.indexOf("MAC") + 9, str.length());
                        macAddress = macAddress.trim();
                        System.out.println("macAddress:" + macAddress);
                        break;
                    }
                }
                p.destroy();
                br.close();
                ir.close();
            } catch (IOException ex) {
            }
            return macAddress;
        }
}
