This package builds on the beans package to add support for message sources and for the Observer design pattern, and the ability for application objects to obtain resources using a consistent API.

There is no necessity for Spring applications to depend on ApplicationContext or even BeanFactory functionality explicitly. One of the strengths of the Spring architecture is that application objects can often be configured without any dependency on Spring-specific APIs.

Interface Summary

Modifier and Type	Interface and Description
public interface	ApplicationContext Central interface to provide configuration for an application.
public interface	ApplicationContextAware Interface to be implemented by any object that wishes to be notified of the `ApplicationContext` that it runs in. Implementing this interface makes sense for example when an object requires access to a set of collaborating beans.
public interface	ApplicationContextInitializer< the application context type C extends ConfigurableApplicationContext> Callback interface for initializing a Spring `ConfigurableApplicationContext` prior to being refreshed.
public interface	ApplicationEventPublisher Interface that encapsulates event publication functionality.
public interface	ApplicationEventPublisherAware Interface to be implemented by any object that wishes to be notified of the ApplicationEventPublisher (typically the ApplicationContext) that it runs in.
public interface	ApplicationListener< the specific `ApplicationEvent` subclass to listen to E extends ApplicationEvent> Interface to be implemented by application event listeners.
public interface	ApplicationStartupAware Interface to be implemented by any object that wishes to be notified of the `ApplicationStartup` that it runs with.
public interface	ConfigurableApplicationContext SPI interface to be implemented by most if not all application contexts.
public interface	EmbeddedValueResolverAware Interface to be implemented by any object that wishes to be notified of a `StringValueResolver` for the resolution of embedded definition values.
public interface	EnvironmentAware Interface to be implemented by any bean that wishes to be notified of the `Environment` that it runs in.
public interface	HierarchicalMessageSource Sub-interface of MessageSource to be implemented by objects that can resolve messages hierarchically.
public interface	Lifecycle A common interface defining methods for start/stop lifecycle control.
public interface	LifecycleProcessor Strategy interface for processing Lifecycle beans within the ApplicationContext.
public interface	MessageSource Strategy interface for resolving messages, with support for the parameterization and internationalization of such messages.
public interface	MessageSourceAware Interface to be implemented by any object that wishes to be notified of the `MessageSource` (typically the ApplicationContext) that it runs in. Note that the `MessageSource` can usually also be passed in as a bean reference (via arbitrary bean properties or constructor arguments), because it is defined as a bean with name `"messageSource"` in the application context.
public interface	MessageSourceResolvable Interface for objects that are suitable for message resolution in a `MessageSource`.
public interface	Phased Interface for objects that may participate in a phased process such as lifecycle management.
public interface	ResourceLoaderAware Interface to be implemented by any object that wishes to be notified of the `ResourceLoader` (typically the ApplicationContext) that it runs in. This is an alternative to a full `ApplicationContext` dependency via the `org.springframework.context.ApplicationContextAware` interface.
public interface	SmartLifecycle An extension of the `Lifecycle` interface for those objects that require to be started upon `ApplicationContext` refresh and/or shutdown in a particular order.

Class Summary

Modifier and Type	Class and Description
public class	ApplicationContextException Exception thrown during application context initialization.
public abstract class	ApplicationEvent Class to be extended by all application events.
public class	NoSuchMessageException Exception thrown when a message can't be resolved.
public class	PayloadApplicationEvent< the payload type of the event T> An `ApplicationEvent` that carries an arbitrary payload.
