Examples of org.springframework.context.support.AbstractApplicationContext.publishEvent()

org.springframework.context.support.AbstractApplicationContext.publishEvent()
Publish the given event to all listeners.
Note: Listeners get initialized after the MessageSource, to be able to access it within listener implementations. Thus, MessageSource implementations cannot publish events. @param event the event to publish (may be application-specific or astandard framework event)

    context.refresh();


    SamplePersonEventListener listener = new SamplePersonEventListener();
    context.addApplicationListener(listener);


    context.publishEvent(new BeforeConvertEvent<Person>(new Person("Dave", "Matthews")));
    assertThat(listener.invokedOnBeforeConvert, is(true));


    listener.invokedOnBeforeConvert = false;
    context.publishEvent(new BeforeConvertEvent<String>("Test"));
    assertThat(listener.invokedOnBeforeConvert, is(false));
