    void

  • Method Details

    • publishEvent

      default void publishEvent(ApplicationEvent event)
      Notify all matching listeners registered with this application of an application event. Events may be framework events (such as ContextRefreshedEvent) or application-specific events.

      Such an event publication step is effectively a hand-off to the multicaster and does not imply synchronous/asynchronous execution or even immediate execution at all. Event listeners are encouraged to be as efficient as possible, individually using asynchronous execution for longer-running and potentially blocking operations.

      Parameters:
      event - the event to publish

      If the specified event is not an ApplicationEvent, it is wrapped in a PayloadApplicationEvent.
