Method Detail

setApplicationContext

public void setApplicationContext(ApplicationContext applicationContext)
                           throws BeansException

Description copied from interface: ApplicationContextAware

Set the ApplicationContext that this object runs in. Normally this call will be used to initialize the object.

Invoked after population of normal bean properties but before an init callback such as InitializingBean.afterPropertiesSet() or a custom init-method. Invoked after ResourceLoaderAware.setResourceLoader(org.springframework.core.io.ResourceLoader), ApplicationEventPublisherAware.setApplicationEventPublisher(org.springframework.context.ApplicationEventPublisher) and MessageSourceAware, if applicable.

Specified by:

setApplicationContext in interface ApplicationContextAware

Parameters:

applicationContext - the ApplicationContext object to be used by this object

Throws:

ApplicationContextException - in case of context initialization errors

BeansException - if thrown by application context methods

BeanInitializationException

getEventListenerFactories

protected java.util.List<EventListenerFactory> getEventListenerFactories()

Return the EventListenerFactory instances to use to handle EventListener annotated methods.

afterSingletonsInstantiated

public void afterSingletonsInstantiated()

Description copied from interface: SmartInitializingSingleton

Invoked right at the end of the singleton pre-instantiation phase, with a guarantee that all regular singleton beans have been created already. ListableBeanFactory.getBeansOfType(java.lang.Class<T>) calls within this method won't trigger accidental side effects during bootstrap.

NOTE: This callback won't be triggered for singleton beans lazily initialized on demand after BeanFactory bootstrap, and not for any other bean scope either. Carefully use it for beans with the intended bootstrap semantics only.

Specified by:

afterSingletonsInstantiated in interface SmartInitializingSingleton

processBean

protected void processBean(java.util.List<EventListenerFactory> factories,
                           java.lang.String beanName,
                           java.lang.Class<?> type)

getTargetClass

private java.lang.Class<?> getTargetClass(java.lang.String beanName,
                                          java.lang.Class<?> type)

getProxyMethod

private java.lang.reflect.Method getProxyMethod(java.lang.Class<?> proxyType,
                                                java.lang.reflect.Method method)
