解决方案二：

 public static String getWindowsMACAddress() {
             String mac = null;
             BufferedReader bufferedReader = null;
             Process process = null;
             try {
                   /**
                    * windows下的命令，显示信息中包含有mac地址信息
                    */
                 process = Runtime.getRuntime().exec("ipconfig /all");
                 bufferedReader = new BufferedReader(new InputStreamReader(process
                         .getInputStream()));
                 String line = null;
                 int index = -1;
                 while ((line = bufferedReader.readLine()) != null) {
                        /**
                         *  寻找标示字符串[physical address]
                         */
                     index = line.toLowerCase().indexOf("物理地址");    //注意用ipconfig -all看一下字符，中英文是不一样的
                     if (index != -1) {
                         index = line.indexOf(":");
                         if (index != -1) {
                                /**
                                 *   取出mac地址并去除2边空格
                                 */
                            mac = line.substring(index + 1).trim();
                        }
                         break;
                     }
                 }
             } catch (IOException e) {
                 e.printStackTrace();
             }finally {
                 try {
                     if (bufferedReader != null) {
                         bufferedReader.close();
                       }
                 }catch (IOException e1) {
                     e1.printStackTrace();
                   }
                 bufferedReader = null;
                 process = null;
             }     

             return mac;
         }
