Spring applicationcontext java class

Interface ApplicationContext

Central interface to provide configuration for an application. This is read-only while the application is running, but may be reloaded if the implementation supports this.

• Bean factory methods for accessing application components. Inherited from ListableBeanFactory .
• The ability to load file resources in a generic fashion. Inherited from the ResourceLoader interface.
• The ability to publish events to registered listeners. Inherited from the ApplicationEventPublisher interface.
• The ability to resolve messages, supporting internationalization. Inherited from the MessageSource interface.
• Inheritance from a parent context. Definitions in a descendant context will always take priority. This means, for example, that a single parent context can be used by an entire web application, while each servlet has its own child context that is independent of that of any other servlet.

getParent

Return the parent context, or null if there is no parent and this is the root of the context hierarchy.

getAutowireCapableBeanFactory

Expose AutowireCapableBeanFactory functionality for this context. This is not typically used by application code, except for the purpose of initializing bean instances that live outside 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.
