获取本机IP
public static String getLocalHostIp() throws SocketException
 {
  Enumeration netInterfaces = NetworkInterface.getNetworkInterfaces();
  while(netInterfaces.hasMoreElements())
  {
   NetworkInterface ni = (NetworkInterface)netInterfaces.nextElement();

   while(inetAddresses.hasMoreElements())
   {

    if(!ip.isLoopbackAddress())
    {
     return ip.getHostAddress();
    }
   }
  }
  return null;
 }

获取本机MAC
public static String getLocalMac() throws IOException
 {
  Process p1 = Runtime.getRuntime().exec("ipconfig   /all");
  BufferedReader br = new BufferedReader(
            new InputStreamReader(
                  p1
                   .getInputStream()));
  String buf = br.readLine();
  while(buf != null)
  {
   if(buf.contains("Physical Address"))
   {
    int i = buf.indexOf("Physical Address") + 36;
    return buf.substring(i).trim();
   }
   buf = br.readLine();
  }
  return "000000";
