What i'm trying to do is next: I have dispatcher that will receive messages of different types and route them to handlers. Dispatcher holds map of , every MessageHandler can process his type of messages, and every handler should register in dispatcher.
So i have "Dispatcher" service which implement interface:
public interface Dispatcher{
public void register(IMessageHandler handler);
public void handle(IMessage message);
}
and several beans that implement interface IMessageHandler:
public interface IMessageHandler{
public void handle(IMessage message);
}
IMessage is also an interface.
I need this instances of IMessageHandler to call "register" method on Dispatcher to register themself, so dispatcher can distribute messages to appropriate handlers.
For now i do next:
@Service(IMessageHandler.class)
public class MessageBHandler implements IMessageHandler {
@Inject
@Reference
Dispatcher dispatcher;
@PostConstruct
public void registerMyself(){
dispatcher.register(this);
}
...
}
But i see in logs that Dispatcher gets create twice. How can i make him singleton?
