Class ApplicationContextAwareProcessor

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

All Implemented Interfaces:

BeanPostProcessor

---

public class ApplicationContextAwareProcessor
extends Object
implements BeanPostProcessor

BeanPostProcessor implementation that passes the ApplicationContext to beans that implement the ResourceLoaderAware, ApplicationEventPublisherAware, MessageSourceAware and/or ApplicationContextAware interfaces. If all of them are implemented, they are satisfied in the given order.

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

Since:

10.10.2003

Method Summary
Object	postProcessAfterInitialization(Object bean, String name)           Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method).
Object	postProcessBeforeInitialization(Object bean, String beanName)           Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method).

Constructor Detail

ApplicationContextAwareProcessor

public ApplicationContextAwareProcessor(ApplicationContext applicationContext)

Create a new ApplicationContextAwareProcessor for the given context.

Method Detail

postProcessBeforeInitialization

public Object postProcessBeforeInitialization(Object bean,
                                              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

Throws:

BeansException - in case of errors

InitializingBean.afterPropertiesSet()

postProcessAfterInitialization

public Object postProcessAfterInitialization(Object bean,
                                             String name)

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

name - the name of the bean

Returns:

the bean instance to use, either the original or a wrapped one

InitializingBean.afterPropertiesSet(), FactoryBean
