Interface ViewAccessControl

public interface ViewAccessControl

Interface to be implemented by Spring beans that will be consulted before the SpringViewProvider creates a view instance. If any of the view access controls deny access, the view provider will act like no such view ever existed, or show an access denied view. Access control beans implementing this interface are called before a view instance is created but can access the annotations on the view bean class through the application context. Unless contextual information from the view instance is needed, this interface should be used instead of a ViewInstanceAccessControl.
