2. Spring Configuration

This standard Spring MVC configuration file creates handlers, configures Tiles, and also internationalization. The context:component-scan registers the PersonController, which is defined in the org.springbyexample.web.servlet.mvc package. The mvc:annotation-driven element registers a DefaultAnnotationHandlerMapping and AnnotationMethodHandlerAdapter. It also sets up type converters and a Bean Validation (JSR-303) validator (if JSR-303 library is present on the classpath). The mvc:view-controller element sets an explicit mapping to the static index page.

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 message resource handling. The LocaleChangeInterceptor is registered as an interceptor with the default handler by the surrounding mvc:interceptors element.
