获取到的parameter为：
order=YM130402cygr_UTb42&app=30996ced018a2a5e&ad=KC%E7%BD%91%E7%BB%9C%E7%94%B5%E8%AF%9D&user=1141058&

SysConfigUtil.getQueryParams(parameter):如下：

public static Map<String,String> getQueryParams(String url) {

       try {

           Map<String, String> params = new HashMap<String, String>();  

               for (String param : url.split("&")) {

                   String[] pair = param.split("=");

                   String key = URLDecoder.decode(pair[0], "UTF-8");

                   String value = "";

                   if (pair.length > 1) {

                       value = URLDecoder.decode(pair[1], "UTF-8");

                   }

                   params.put(key, value);  

               }  

           return params;

       } catch (UnsupportedEncodingException ex) {

           throw new AssertionError(ex);

       }

   }
