RESTEasyのMessageBodyReaderのエラーメッセージ

Question

だから、私はRESTアプリケーションを持っているし、次のようになります。私はResteasyClientフレームワークを使用して、私のRESTクライアントを実装してdocumentation

@GET 
@Path("/getpartners") 
@Produces(MediaType.APPLICATION_JSON) 
HashMap<Integer, PartnerEntityDTO> getPartners(); 

に応じて以下に引用されるようになります

@GET 
@Produces(MediaType.APPLICATION_JSON) 
@Path("/getpartners") 
public HashMap<Integer, PartnerEntityDTO> getPartners() throws NamingException { 
    //body 
} 

要点は、クライアント側のHashMapをRESTサービスから取得したいのですが、私がブラウザを使用していれば問題なく取得できます。しかし、スイングクライアントを使用している場合、何かが間違っています。スイングクライアントでこのコードを使用して、呼び出しと応答を処理します。

//Resteasy client 
    RegisterBuiltin.register(ResteasyProviderFactory.getInstance()); 
    PartnerServiceClientInterface partnerServiceClientInterface = ProxyFactory.create(PartnerServiceClientInterface.class, "http://localhost:8080/dilib/partners"); 
    **//Sources.java:66** 
    String restResponse = partnerServiceClientInterface.getPartners().toString(); 
    JsonParser jsonParser = new JsonParser(); 
    JsonArray partnerDataInJson = jsonParser.parse(restResponse).getAsJsonArray(); 
    int size = partnerDataInJson.size(); 
    Gson gson = new Gson(); 
    HashMap<Integer, PartnerEntityDTO> partnerDataFromServer = new HashMap<Integer, PartnerEntityDTO>(); 
    for(int i = 0; i < size; i++) { 
     PartnerEntityDTO deserializedPartnerEntityDTO = gson.fromJson(partnerDataInJson.get(i), PartnerEntityDTO.class); 
     partnerDataFromServer.put(i, deserializedPartnerEntityDTO); 
    } 

エラーメッセージはこれです：私はこのエラーメッセージとのRESTEasyのドキュメントについてググ

インターセプタの一部でlinketですが、問題が何であるか私にとっては明確ではありません。

事前にお問い合わせいただきありがとうございます。

Answer 1

クラスパスにjettisonプロバイダがありますか？あなたはMavenを使用している場合は、この依存関係を追加します。

<dependency> 
     <groupId>org.jboss.resteasy</groupId> 
     <artifactId>resteasy-jettison-provider</artifactId> 
     <version>${resteasy.version}</version> 
    </dependency> 

は、使用しているバージョンと ${resteasy.version}を交換してください。
