Method Detail

postProcessBeforeDestruction

void postProcessBeforeDestruction(Object bean,
                                  String beanName)

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
