@Indexed(BeanInitializedEventListener.class) @FunctionalInterface public interface BeanInitializedEventListener<T> extends EventListener

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

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