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);
       }
   }
