Application events are available since the very beginning of the Spring framework as a mean for loosely coupled components to exchange information. One of the most well known usage of application events is the following:

@Component
public class MyListener 
        implements ApplicationListener<ContextRefreshedEvent> {
  
    public void onApplicationEvent(ContextRefreshedEvent event) {
        ...
 }
