是否有任何方法可以在此@ClientEndpoint类中启用cdi(仍然使用注释而不是编程的终结点类)?我正在使用wildfly 14和Java 8。
以下是创建会话的代码,将类名传递给“ createConnection”方法:
@ApplicationScoped //TODO move this to be request scoped
public class SessionProducer {
@Produces
public Session getSession(InjectionPoint ip) {
SessionAnnotation annotation = ip.getAnnotated().getAnnotation(SessionAnnotation.class);
if(annotation != null) {
Class clazz = annotation.clazz();
String url = annotation.serverURL();
WebSocketContainer webSocketContainer = ContainerProvider.getWebSocketContainer();
try {
return webSocketContainer.connectToServer(clazz, new URI(url)); //<----------this is the line that uses the annotated class (clazz is a reference to the class)
} catch (DeploymentException | IOException | URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return null;
}
/**
* The destroy/disposer metho for the session
* @param session
*/
public void close(@Disposes Session session) {
try {
session.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
这是带注释的终结点类:
@ClientEndpoint
public class CryptoCompareWSClient {
@Inject
@CryptoCompare
private Event<String> cryptoCompareEvent; //<--------this is always null, no cdi happens
public CryptoCompareWSClient() {
System.out.println("constructor");
//cryptoCompareEvent = new Event();
}
@PostConstruct
public void init() {
System.out.println("post construct"); //<---------this never gets called
}
@OnOpen
public void open(Session session) {
//session.getAsyncRemote().sendText("SubAdd: { subs: ['0~Poloniex~BTC~USD'] }" /*"test"*/);
System.out.println("opened");
}
@OnClose
public void close(Session session) {
System.out.println("Session " + session + " closed");
}
@OnError
public void error(Throwable error) {
System.out.println("Error: " + error.getMessage());
}
@OnMessage
public void message(String message, Session session) {
System.out.println("Message");
//cryptoCompareEvent.fireAsync(message);
}
}
有什么方法可以在启用的类中启用cdi吗?
谢谢。
