Method Detail

postProcessBeforeInitialization

public Object postProcessBeforeInitialization(Object bean,
                                              String beanName)
                                       throws org.springframework.beans.BeansException

Specified by:

postProcessBeforeInitialization in interface org.springframework.beans.factory.config.BeanPostProcessor

Throws:

org.springframework.beans.BeansException

postProcessAfterInitialization

public Object postProcessAfterInitialization(Object bean,
                                             String beanName)
                                      throws org.springframework.beans.BeansException

Specified by:

postProcessAfterInitialization in interface org.springframework.beans.factory.config.BeanPostProcessor

Throws:

org.springframework.beans.BeansException

getAdapterInterface

protected abstract Class<?> getAdapterInterface()

Returns the interface that the adapter implements to connect the annotated method to the actual interface definition. Calls to methods declared on this interface are passed to the adapter, while other method calls will be forwarded to the annotated object itself.

Note: this *must* be an interface. It may not be an (abstract) class.

Returns:

the interface that the adapter implements to connect the annotated method to the actual interface definition

isPostProcessingCandidate

protected abstract boolean isPostProcessingCandidate(Class<?> targetClass)

Indicates whether an object of the given targetClass should be post processed.

Parameters:

targetClass - The type of bean

Returns:

true to post process bean of given type, false otherwise

postProcessBeforeDestruction

public void postProcessBeforeDestruction(Object bean,
                                         String beanName)
                                  throws org.springframework.beans.BeansException

Specified by:

postProcessBeforeDestruction in interface org.springframework.beans.factory.config.DestructionAwareBeanPostProcessor

Throws:

org.springframework.beans.BeansException

initializeAdapterFor

protected abstract Subscribable initializeAdapterFor(Object bean)

Create an AnnotationEventListenerAdapter instance of the given bean. This adapter will receive all event handler calls to be handled by this bean.

Parameters:

bean - The bean that the EventListenerAdapter has to adapt

Returns:

an event handler adapter for the given bean

getApplicationContext

protected org.springframework.context.ApplicationContext getApplicationContext()

Returns the ApplicationContext this Bean Post Processor is registered in.

Returns:

the ApplicationContext this Bean Post Processor is registered in

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Throws:

org.springframework.beans.BeansException
