RequestFactory를 사용하여 JSON-RPC 서비스를 호출하는 방법

Question

또는 GWT에서 이것을 보관하는 가장 좋은 방법은 무엇입니까?

RequestFactory를 사용하여 매개 변수를 사용하여 간단한 서비스를 호출하는 방법에 대한 코드를 게시하십시오.

UPDATE :

토마스, 난 당신의 제안을 내 코드를 업데이트했다.

Cat는이 ValueProxy 주석 @JsonRpcProxy으로해야한다 :

public interface MyRequestFactory extends RequestFactory { 
    MyRequestFactory INSTANCE = GWT.create(MyRequestFactory.class); 

    MyRequestContext myRequestContest(); 
} 

@JsonRpcService 
public interface MyRequestContext extends RequestContext { 

    UserFullFormattedName userFullFormattedName(); 

    @JsonRpcWireName(value = "GetUserFullFormattedName") 
    public interface UserFullFormattedName extends Request<String> { 
    } 
} 

public static EventBus EVENT_BUS = GWT.create(SimpleEventBus.class); 

public void onModuleLoad() { 

    DefaultRequestTransport requestTransport = new DefaultRequestTransport(); 
    requestTransport.setRequestUrl("../services/service.ashx"); 

    MyRequestFactory.INSTANCE.initialize(EVENT_BUS, requestTransport); 

    MyRequestFactory.INSTANCE.myRequestContext().userFullFormattedName().fire(new Receiver<String>() { 

     @Override 
     public void onSuccess(String response) { 
      System.out.println(response); 

     } 
    }); 

이 코드는 실패 또한

@JsonRpcProxy 
interface Cat extends ValueProxy { 
    String getName(); 
    String getId(); 
} 

, 내가 같이 필요한 @JsonRpcWireName 확실하지 않다 그 값은 메소드 이름과 같습니다.
