问题
I am developing a web app and trying to integrate a chat (for now). I am using Spring and Atmosphere to do this. I managed to get the chat working, but now I seem to have run into a problem. I am using the @ManagedService in a separate servlet (similar to the atmosphere-chat-multiroom example) and now I need to access to a bean that is inside the spring application. For the rest of the servlets that I am using, this works flawlessly, but I am at a dead end when it comes to doind this in Atmosphere ManagedService, the service is always returned as null.
Does anyone have any clue as to what I can do?
@ManagedService(path = "{room: [a-zA-Z][a-zA-Z_0-9]*}")
@Singleton
public class ChatRoom {
private final Logger logger = LoggerFactory.getLogger(ChatRoom.class);
private final ConcurrentHashMap<String, String> users = new ConcurrentHashMap<String, String>();
private String chatroomName;
private String mappedPath;
private BroadcasterFactory factory;
@Autowired
IFriendsServices friendServices;
@Message(encoders = { JacksonEncoder.class }, decoders = { UserDecoder.class })
public void onPrivateMessage(ChatUserMessageDTO user) throws IOException {
String userUUID = users.get(user.getUser());
friendServices.createChatMessage(user.getUser(), user.getSource(), user.getMessage());
if (userUUID != null) {
AtmosphereResource r = AtmosphereResourceFactory.getDefault().find(userUUID);
if (r != null) {
ChatProtocolMessageDTO m = new ChatProtocolMessageDTO(user.getSource(), user.getMessage(),
users.keySet(), factory.lookupAll());
factory.lookup(mappedPath).broadcast(m, r);
}
}
}
