Just do make in the root dir and the project will compile and run.
Do GET to http://localhost:8080/Events/Normal and check on your command line the output that should be similar to:
Library AbstractObserverNormalEvent: Normal event message 0 Event qualifiers[[@org.acme.NormalEvent(), @javax.enterprise.inject.Any()]]
Runner NormalEventImpl: Normal event message 0
Do GET to http://localhost:8080/Events/Important and check on your command line the output that should be similar to:
Library AbstractObserverNormalEvent: Important event message 0 Event qualifiers[[@org.acme.ImportantEvent(), @javax.enterprise.inject.Any()]]
Runner NormalEventImpl: Important event message 0
Library AbstractObserverImportantEvent: Important event message 0 Event qualifiers[[@org.acme.ImportantEvent(), @javax.enterprise.inject.Any()]]
Runner ImportantEventImpl: Important event message 0
With the two observers defined as:
public abstract class AbstractObserverNormalEvent {
public abstract void eventFired(final String message);
public void observer(@Observes @NormalEvent final String message, final EventMetadata metadata) {
System.out.println("Library AbstractObserverNormalEvent: " + message + " Event qualifiers[" + metadata.getQualifiers().toString() + "]");
eventFired(message);
}
}
public abstract class AbstractObserverImportantEvent {
public abstract void eventFired(final String message);
public void observer(@Observes @ImportantEvent final String message, final EventMetadata metadata) {
System.out.println("Library AbstractObserverImportantEvent: " + message + " Event qualifiers[" + metadata.getQualifiers().toString() + "]");
eventFired(message);
}
}We can see that the AbstractObserverNormalEvent.observer() shouldn't be triggered for the event with the @org.acme.ImportantEvent() qualifier, nevertheless, it is and this is the issue in question.
Debugging the problem I can see that the observer method in the AbstractObserverNormalEvent.observer() does not have the @org.acme.NormalEvent() qualifier and so it behaves like a general observer.
