public interface ApplicationContext extends EnvironmentCapable, ListableBeanFactory, HierarchicalBeanFactory, MessageSource, ApplicationEventPublisher, ResourcePatternResolver
An ApplicationContext provides:
ListableBeanFactory
.
ResourceLoader
interface.
ApplicationEventPublisher
interface.
MessageSource
interface.
In addition to standard BeanFactory
lifecycle capabilities, ApplicationContext implementations detect and invoke
ApplicationContextAware
beans as well as ResourceLoaderAware
,
ApplicationEventPublisherAware
and MessageSourceAware
beans.

BeanFactory

This is not typically used by application code, except for the purpose of initializing bean instances that live outside of the application context, applying the Spring bean lifecycle (fully or partly) to them.
Alternatively, the internal BeanFactory exposed by the
ConfigurableApplicationContext
interface offers access to the
AutowireCapableBeanFactory
interface too. The present method mainly
serves as a convenient, specific facility on the ApplicationContext interface.
NOTE: As of 4.2, this method will consistently throw IllegalStateException after the application context has been closed. In current Spring Framework versions, only refreshable application contexts behave that way; as of 4.2, all application context implementations will be required to comply.
IllegalStateException
- if the context does not support the
AutowireCapableBeanFactory
interface, or does not hold an
autowire-capable bean factory yet (e.g. if refresh()
has
never been called), or if the context has been closed alreadyConfigurableApplicationContext.refresh()
