public interface: BeanPostProcessor [javadoc | source]

All Known Implementing Classes:
PersistenceExceptionTranslationPostProcessor, AutowiredAnnotationBeanPostProcessor, ActionServletAwareProcessor, AdvisorAdapterRegistrationManager, ScriptFactoryPostProcessor, PortletContextAwareProcessor, SimplePortletPostProcessor, RequiredAnnotationBeanPostProcessor, CommonAnnotationBeanPostProcessor, DefaultAdvisorAutoProxyCreator, AnnotationAwareAspectJAutoProxyCreator, BeanPostProcessorChecker, PersistenceAnnotationBeanPostProcessor, BootstrapContextAwareProcessor, BeanNameAutoProxyCreator, SmartInstantiationAwareBeanPostProcessor, DestructionAwareBeanPostProcessor, ServletContextAwareProcessor, SimpleServletPostProcessor, InfrastructureAdvisorAutoProxyCreator, InstantiationAwareBeanPostProcessor, InstantiationAwareBeanPostProcessorAdapter, AspectJAwareAdvisorAutoProxyCreator, MergedBeanDefinitionPostProcessor, LoadTimeWeaverAwareProcessor, AbstractAdvisorAutoProxyCreator, InitDestroyAnnotationBeanPostProcessor, ApplicationContextAwareProcessor, AbstractAutoProxyCreator

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 #postProcessBeforeInitialization , while post-processors that wrap beans with proxies will normally implement #postProcessAfterInitialization .

Method from org.springframework.beans.factory.config.BeanPostProcessor Summary:
postProcessAfterInitialization, postProcessBeforeInitialization

Method from org.springframework.beans.factory.config.BeanPostProcessor Detail:
public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's `afterPropertiesSet` or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original. In case of a FactoryBean, this callback will be invoked for both the FactoryBean instance and the objects created by the FactoryBean (as of Spring 2.0). The post-processor can decide whether to apply to either the FactoryBean or created objects or both through corresponding `bean instanceof FactoryBean` checks. This callback will also be invoked after a short-circuiting triggered by a InstantiationAwareBeanPostProcessor#postProcessBeforeInstantiation method, in contrast to all other BeanPostProcessor callbacks.
public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's `afterPropertiesSet` or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.
