动态播放！ 模板链接

Question

I"m having trouble generating dynamic links from strings. I have a controller which renders a page:

public class ViewController extends Controller {
   public static void index() {
      Map<String, String> breadcrumbsMap = new LinkedHashMap<String, String>();
      breadcrumbsMap.put("Home", "ViewController.index()");
      breadcrumbsMap.put("User", "UserController.index()");

      render(breadcrumbsMap);
   }
}

The page has markup that looks like (but doesn't work):

<ul id="breadcrumbs">
    #{list items:breadcrumbsMap.keySet(), as:'key'}
       <li>#{a @breadcrumbsMap.get(key)}${key}#{/a}</li> 
    #{/list}
</ul>

I can't figure out how to make the markup turn the string into a link. From the docs, something standard would be:

#{a @Application.logout()}Disconnect#{/a}

Answer 1

<a href="breadcrumbsMap.get(key)">&{key}</a>

Answer 2

Try

breadcrumbsMap.put("Home", Router.reverse("ViewController.index()", emptyMap).url);
breadcrumbsMap.put("User", Router.reverse("UserController.index()", emptyMap).url);

And display the link like any string:

<a href="breadcrumbsMap.get(key)">${key}</a>
