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

getAdapterInterfaces

protected abstract Class<?>[] getAdapterInterfaces()

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

initializeAdapterFor

protected abstract T initializeAdapterFor(Object bean,
                                          ParameterResolverFactory parameterResolverFactory,
                                          HandlerDefinition handlerDefinition)

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

parameterResolverFactory - The parameter resolver factory that provides the parameter resolvers for the annotated handlers

handlerDefinition - The handler definition used to create concrete handlers

Returns:

an event handler adapter for the given bean

setParameterResolverFactory

public void setParameterResolverFactory(ParameterResolverFactory parameterResolverFactory)

Sets the ParameterResolverFactory to create the Parameter Resolvers with that provide the parameter values for the handler methods.

Parameters:

parameterResolverFactory - The parameter resolver factory to resolve parameter values with

setHandlerDefinition

public void setHandlerDefinition(HandlerDefinition handlerDefinition)

Sets the HandlerDefinition to create concrete handlers.

Parameters:

handlerDefinition - The handler definition used to create concrete handlers

setBeanFactory

public void setBeanFactory(org.springframework.beans.factory.BeanFactory beanFactory)
                    throws org.springframework.beans.BeansException

Specified by:

setBeanFactory in interface org.springframework.beans.factory.BeanFactoryAware

Throws:

org.springframework.beans.BeansException
