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

Method Details
-
postProcessBeforeDestruction
Apply this BeanPostProcessor to the given bean instance before its destruction, e.g. invoking custom destruction callbacks.Like DisposableBean's
destroy
and a custom destroy method, this callback will only apply to beans which the container fully manages the lifecycle for. This is usually the case for singletons and scoped beans.- Parameters:
bean
- the bean instance to be destroyedbeanName
- the name of the bean- Throws:
BeansException
- in case of errors- See Also:
-
requiresDestruction
Determine whether the given bean instance requires destruction by this post-processor.The default implementation returns
true
. If a pre-5 implementation ofDestructionAwareBeanPostProcessor
does not provide a concrete implementation of this method, Spring silently assumestrue
as well.- Parameters:
bean
- the bean instance to check- Returns:
true
ifpostProcessBeforeDestruction(java.lang.Object, java.lang.String)
is supposed to be called for this bean instance eventually, orfalse
if not needed- Since:
- 4.3
