Class ApplicationContextAwareProcessor

java.lang.Object
  org.springframework.context.support.ApplicationContextAwareProcessor

All Implemented Interfaces:

BeanPostProcessor

 class ApplicationContextAwareProcessor
extends java.lang.Object
implements BeanPostProcessor

BeanPostProcessor implementation that passes the ApplicationContext to beans that implement the EmbeddedValueResolverAware, ResourceLoaderAware, MessageSourceAware, ApplicationEventPublisherAware and/or ApplicationContextAware interfaces.

Implemented interfaces are satisfied in order of their mention above.

Application contexts will automatically register this with their underlying bean factory. Applications do not use this directly.

Method Detail

postProcessBeforeInitialization

public java.lang.Object postProcessBeforeInitialization(java.lang.Object bean,
                                                        java.lang.String beanName)
                                                 throws BeansException

Description copied from interface: BeanPostProcessor

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.

Specified by:

postProcessBeforeInitialization in interface BeanPostProcessor

Parameters:

bean - the new bean instance

beanName - the name of the bean

Returns:

the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked

Throws:

BeansException - in case of errors

postProcessAfterInitialization

public java.lang.Object postProcessAfterInitialization(java.lang.Object bean,
                                                       java.lang.String beanName)

Description copied from interface: BeanPostProcessor

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(java.lang.Class, java.lang.String) method, in contrast to all other BeanPostProcessor callbacks.

Specified by:

postProcessAfterInitialization in interface BeanPostProcessor

Parameters:

bean - the new bean instance

beanName - the name of the bean

Returns:

the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked
