import java.util.EventListener;


Allows hooking into bean instantiation at the point prior to when PostConstruct initialization hooks have been called and in the case of bean Provider instances the Provider.get() method has not yet been invoked.




This allows (for example) customization of bean properties prior to any initialization logic or factory logic.
