@ApplicationScope is a specialization of @Scope for a component whose lifecycle is bound to the current web application.

Specifically, @ApplicationScope is a composed annotation that acts as a shortcut for @Scope("application") with the default proxyMode set to TARGET_CLASS.

@ApplicationScope may be used as a meta-annotation to create custom composed annotations.
