public void postProcessBeforeDestruction(Object bean, String beanName) throws BeansException 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.

requiresDestruction	back to summary
public default boolean requiresDestruction(Object bean) Determine whether the given bean instance requires destruction by this post-processor. The default implementation returns `true`. If a pre-5 implementation of `DestructionAwareBeanPostProcessor` does not provide a concrete implementation of this method, Spring silently assumes `true` as well. Parameters bean:Object the bean instance to check Returns:boolean `true` if `postProcessBeforeDestruction` is supposed to be called for this bean instance eventually, or `false` if not needed Since 4.3

public default boolean requiresDestruction(Object bean)

Determine whether the given bean instance requires destruction by this post-processor.

Parameters

bean:Object: the bean instance to check

Returns:boolean

true if postProcessBeforeDestruction is supposed to be called for this bean instance eventually, or false if not needed
