Tyrus - 簡單的java應用程序 - 找不到實現類

Question

我正在開發簡單的應用程序以幫助我學習Java中的WebSocket和Tyrus概念。這裏是我的服務器端（服務器端點）和我的pom.xml和我的客戶端和pom.xml中：

服務器端

@ServerEndpoint(value="/websocket/{client-id}") 
    public class MyServerEndpoint { 

     private static final LinkedList<Session> clients = new LinkedList<Session>(); 

     @OnOpen 
     public void onOpen(Session session) { 
      clients.add(session); 

     } 
     @OnMessage 
     public void onMessage(String message,@PathParam("client-id") String clientId) { 
      for (Session client : clients) { 
       try { 
        client.getBasicRemote().sendObject(clientId+": "+message);   

       } catch (IOException e) { 
        e.printStackTrace(); 
       } catch (EncodeException e) { 
        e.printStackTrace(); 
       } 
      } 
     } 
     @OnClose 
     public void onClose(Session peer) { 
      clients.remove(peer); 
     } 
    } 

的pom.xml

    </project> 

客戶端

MyClient.java 

@ClientEndpoint 
public class MyClient { 
    @OnOpen 
    public void onOpen(Session session) { 
     System.out.println("Connected to endpoint: " + session.getBasicRemote()); 
     try { 
      session.getBasicRemote().sendText("Hello"); 
     } catch (IOException ex) { 
     } 
    } 

    @OnMessage 
    public void onMessage(String message) { 
     System.out.println(message); 
    } 

    @OnError 
    public void onError(Throwable t) { 
     t.printStackTrace(); 
    } 
} 

App.java

public class App { 

    public Session session; 

    protected void start() 
      { 

      WebSocketContainer container = ContainerProvider.getWebSocketContainer(); 

      String uri = "ws://localhost:8080/TyrusJacpFXClient/websocket/desktop-client"; 
      System.out.println("Connecting to " + uri); 
      try { 
       session = container.connectToServer(MyClient.class, URI.create(uri)); 
      } catch (DeploymentException e) { 
       e.printStackTrace(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      }    

    } 
    public static void main(String args[]){ 
     App client = new App(); 
     client.start(); 

     BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); 
     String input = ""; 
     try { 
      do{ 
       input = br.readLine(); 
       if(!input.equals("exit")) 
        client.session.getBasicRemote().sendText(input); 

      }while(!input.equals("exit")); 

     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
    } 
} 

的pom.xml

</project> 

我收到此錯誤：

Exception in thread "main" java.lang.RuntimeException: Could not find an implementation class. 
at javax.websocket.ContainerProvider.getWebSocketContainer(ContainerProvider.java:73) 
at org.hwc.App.start(App.java:25) 
at org.hwc.App.main(App.java:40) 

有人可以幫我看這個問題？服務器運行在GlassFish 4.0內部

Answer 1

您有依賴關係問題。這一個：

<dependency> 
     <groupId>org.glassfish.tyrus</groupId> 
     <artifactId>tyrus-container-grizzly</artifactId> 
     <version>1.1</version> 
    </dependency> 

是不正確的。您需要使用[1]（灰熊基於客戶端）：

<dependency> 
     <groupId>org.glassfish.tyrus</groupId> 
     <artifactId>tyrus-container-grizzly-client</artifactId> 
     <version>1.8.3</version> 
    </dependency> 

或[2]（JDK 7 NIO客戶IMPL）

<dependency> 
     <groupId>org.glassfish.tyrus</groupId> 
     <artifactId>tyrus-container-jdk-client</artifactId> 
     <version>1.8.3</version> 
    </dependency>
