The context:component-scan registers the PersonController, which is defined
in the org.springbyexample.web.servlet.mvc package. The first import configures the JPA configuration
for managing a person and the second configures Spring MVC.

This standard Spring MVC configuration file creates handlers, configures Tiles, and also internationalization.
The classnameControllerMappings bean enables convention based mappings for reduced configuration.
It is configured to be case sensitive, so a controller called StudentPersonController would map to the URL
'/studentPerson'. Although it defaults to case insensitive and would then map to the URL '/studentperson'.
The default handler is set with the UrlFilenameViewController, which will handle any requests not handled by a convention based controller.
The tilesConfigurer bean configures tiles and
dynamicTilesViewResolver takes the url of a request and uses it for the body in a Tiles template.
The last three beans configure locale and messsage resource handling.
