String nonce_str = "dzzb" + new SimpleDateFormat("yyyyMMddHHmmss").format(new Date());
String stringSignTemp = "mch_id=" + MCHID + "&nonce_str=" + nonce_str + "&sign_type=MD5"
+ "&key=" + KEY;
String sign = MD5Util.MD5(stringSignTemp).toUpperCase();
String xml = "<xml>" + "<mch_id>" + MCHID + "</mch_id>" + "<nonce_str>" + nonce_str + "</nonce_str>"
+ "<sign_type>MD5</sign_type>" + "<sign>" + sign + "</sign>" + "</xml>";
