SpringContext ApplicationReadyEvent Sınıfı

Giriş
Şu satırı dahil ederiz.

import org.springframework.boot.context.event.ApplicationReadyEvent;

Açıklaması şöyle

Event published as late as conceivably possible to indicate that the application is ready to service requests. The source of the event is the SpringApplication itself, but beware of modifying its internal state since all initialization steps will have been completed by then.
