Examples of SmartInitializingSingleton

• org.springframework.beans.factory.SmartInitializingSingleton
  Callback interface triggered at the end of the singleton pre-instantiation phase during {@link BeanFactory} bootstrap. This interface can be implemented bysingleton beans in order to perform some initialization after the regular singleton instantiation algorithm, avoiding side effects with accidental early initialization (e.g. from {@link ListableBeanFactory#getBeansOfType} calls).In that sense, it is an alternative to {@link InitializingBean} which getstriggered right at the end of a bean's local construction phase.

  This callback variant is somewhat similar to {@link org.springframework.context.event.ContextRefreshedEvent} but doesn'trequire an implementation of {@link org.springframework.context.ApplicationListener}, with no need to filter context references across a context hierarchy etc. It also implies a more minimal dependency on just the {@code beans} packageand is being honored by standalone {@link ListableBeanFactory} implementations,not just in an {@link org.springframework.context.ApplicationContext} environment.

  NOTE: If you intend to start/manage asynchronous tasks, preferably implement {@link org.springframework.context.Lifecycle} instead which offersa richer model for runtime management and allows for phased startup/shutdown. @author Juergen Hoeller @since 4.1 @see org.springframework.beans.factory.config.ConfigurableListableBeanFactory#preInstantiateSingletons()
