Annotation Type EventListener
Marks a bean method that runs when start-up is over, after every
CommandLineRunner and
ApplicationRunner.
The method takes a ApplicationReadyEvent, or
nothing. That event is the only one sent: Spring's context events
(refreshed, started) all fall at that moment here, because the build wires
the beans and there is no context to refresh. Listening for any other
type, or for an application event of your own, is a build error; call
the other bean instead.
