- All Superinterfaces:
    BeanPostProcessor
  All Known Implementing Classes:
    CommonAnnotationBeanPostProcessor, InitDestroyAnnotationBeanPostProcessor, PersistenceAnnotationBeanPostProcessor, SimplePortletPostProcessor, SimpleServletPostProcessor

      public interface DestructionAwareBeanPostProcessor
      extends BeanPostProcessor

  Subinterface of `BeanPostProcessor` that adds a before-destruction callback.

  The typical usage will be to invoke custom destruction callbacks on specific bean types, matching corresponding initialization callbacks.

    - #### postProcessBeforeDestruction

          void postProcessBeforeDestruction(Object bean,
                                          String beanName)
                                            throws BeansException

      Apply this BeanPostProcessor to the given bean instance before its destruction. Can invoke custom destruction callbacks.

      Like DisposableBean's `destroy` and a custom destroy method, this callback just applies to singleton beans in the factory (including inner beans).

      Parameters:
        `bean` - the bean instance to be destroyed
        `beanName` - the name of the bean
      Throws:
        `BeansException` - in case of errors
