springmvc-router evaluation

gistfile1.java

My route file is say:
GET   /hello/{id}    controller.do
GET   /hello          controller.dont


public String do(@PathVariable String id) {
      
      // id is 123

      for (Router.Route route : Router.routes) {
         if (route.getPath().startsWith("/hello")) {
             list.add(route.path);
         }
      }

      /* here my list contains:
         /hello, 
         /hello/{id}
      */
}

I was hoping Router would do the evaluation out-of-the-box with the given args. Then again, it doesn't do this way. How do I force Router to evaluate paths with the params, something like:

/hello
/hello/123

I found this workaround, but I was wondering if there is an easy way to do this:

     Map<String, Object> args = new HashMap<String, Object>();

      for (int i = 0; i < route.getArgs().size(); i++) {
         args.put(route.getArgs().get(i).getName(), params[i]);
      }

      for (Router.Route route : Router.routes) {
         if (route.getPath().startsWith("/hello")) {
            Router.ActionDefinition action = Router.reverse(route.action, args);

            list.add(action.url);
         }
      }

Any other suggestions?
