ApplicationContextEvent class abstract

The base class of the events a context publishes about itself: refreshed, started, stopped, paused, restarted, closed.

Applications receive these events; they never create them. Listen to this base class to react to all of them, or to one subclass for one moment of the context's life. Events published in a child context reach the parent's listeners too; compare applicationContext when that matters.

// Logs every state change of every context.
@Component()
@Log()
class ContextLog {
  @EventListener()
  void on(ApplicationContextEvent event) =>
      log.info('${event.runtimeType} of ${event.applicationContext.id}');
}

Spring (Java):

@EventListener
void on(ApplicationContextEvent event) { ... }
