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. Note that configuration
via bean references is preferable to implementing this interface just
for bean lookup purposes.
This interface can also be implemented if an object needs access to file
resources, i.e. wants to call getResource, or access to the MessageSource.
However, it is preferable to implement the more specific ResourceLoaderAware
interface or receive a reference to the MessageSource bean in that scenario.
Note that Resource dependencies can also be exposed as bean properties
of type Resource, populated via Strings with automatic type conversion by
the bean factory. This removes the need for implementing any callback
interface just for the purpose of accessing a specific file resource.
ApplicationObjectSupport is a convenience base class for
application objects, implementing this interface.
For a list of all bean lifecycle methods, see the BeanFactory javadocs.
