Examples of BeanPostProcessor

org.springframework.beans.factory.config.BeanPostProcessor
Factory hook that allows for custom modification of new bean instances, e.g. checking for marker interfaces or wrapping them with proxies.
ApplicationContexts can autodetect BeanPostProcessor beans in their bean definitions and apply them to any beans subsequently created. Plain bean factories allow for programmatic registration of post-processors, applying to all beans created through this factory.
Typically, post-processors that populate beans via marker interfaces or the like will implement {@link #postProcessBeforeInitialization}, while post-processors that wrap beans with proxies will normally implement {@link #postProcessAfterInitialization}. @author Juergen Hoeller @since 10.10.2003 @see InstantiationAwareBeanPostProcessor @see DestructionAwareBeanPostProcessor @see ConfigurableBeanFactory#addBeanPostProcessor @see BeanFactoryPostProcessor
