Tyrus - 简单的java应用程序 - 找不到实现类

Question

我正在开发简单的应用程序来帮助我学习Java中的WebSocket和Tyrus概念.这是我的服务器端(服务器端点)和我的pom.xml以及我的客户端和pom.xml:

服务器端

 @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

客户端

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

          <target>1.8</target>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

我收到此错误:

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)

有人可以帮我看看问题吗？服务器在GlassFish 4.0中运行

Answer 1

你有依赖问题.这个:

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

是不正确的.你需要使用[1](基于灰熊的客户端):

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

或[2](jdk 7 NIO客户端impl)

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