创建 Restlet Authorizer 进行细粒度授权

我正在尝试使用 Restlet 实现 RESTful API，但除了基本的角色和方法授权器之外，几乎没有发现任何其他内容。我已将用户可以访问的路线和这些路线的方法存储在数据库中。我现在遇到的问题是如何获取Authorizer中的路径。这是我需要收集的资源吗？我到底应该如何路由到授权者？我已经发布了到目前为止我所拥有的内容，正在寻找如何在我的授权者中获取路径或资源。任何信息都值得赞赏，我浏览了书籍和许多通用示例，但没有找到我正在寻找的安静内容。

我的路由应用程序：

public class MyRoutingApp extends org.restlet.Application {

    @Override  
    public synchronized Restlet createInboundRoot() { 

        Context context = getContext();
        Router router = new Router(context);

        router.attach("/user", Users.class);
        router.attach("/post", Posts.class);
        router.attach("/comment", Comments.class);

        ChallengeAuthenticator authenticator = new ChallengeAuthenticator( 
                context, ChallengeScheme.HTTP_BASIC, "My test realm" );

        //create Verifier to ensure that the user is authenicated
        MyVerifier verifier = new MySecretVerifier();
        //grab user Roles and add them to the request
        MyEnroler enroler = new MyEnroler();

        authenticator.setVerifier( verifier );
        authenticator.setEnroler( enroler );

        //Looks up if user can be allowed to resource
        MyAuthorizer authorizer = new MyAuthorizer();
        authorizer.setNext( router );

        authenticator.setNext( authorizer );
        return authenticator; 
    }
}

我的授权人：

public class MyAuthorizer extends Authorizer {

    @Override
    protected boolean authorize( Request request, Response response ) {

        //has the security roles and user from verifier and enroler
        ClientInfo info = request.getClientInfo();
        //get http method
        Method method = request.getMethod();

        //need to get the route or resource user is attempting to access
        //allow or disallow access based on roles and method
    }
}

目标资源 URI 可通过 Request#getResouceRef().getRemainingPart() 获得。
