Package org.springframework.context.event

Class EventListenerMethodProcessor

java.lang.Object

org.springframework.context.event.EventListenerMethodProcessor

All Implemented Interfaces:

Aware, BeanFactoryPostProcessor, SmartInitializingSingleton, ApplicationContextAware

public class EventListenerMethodProcessor
extends Object
implements SmartInitializingSingleton, ApplicationContextAware, BeanFactoryPostProcessor

Registers EventListener methods as individual ApplicationListener instances. Implements BeanFactoryPostProcessor (as of 5.1) primarily for early retrieval, avoiding AOP checks for this processor bean and its EventListenerFactory delegates.

Since:

4.2

Method Details

setApplicationContext

public void setApplicationContext(ApplicationContext applicationContext)

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

postProcessBeanFactory

public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory)

Description copied from interface: BeanFactoryPostProcessor

Modify the application context's internal bean factory after its standard initialization. All bean definitions will have been loaded, but no beans will have been instantiated yet. This allows for overriding or adding properties even to eager-initializing beans.

Specified by:

postProcessBeanFactory in interface BeanFactoryPostProcessor

Parameters:

beanFactory - the bean factory used by the application context

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
