22  * Convenience subclass of UrlBasedViewResolver that supports FreeMarkerView
23  * (i.e. FreeMarker templates) and custom subclasses of it.
24  *
25  * <p>The view class for all views generated by this resolver can be specified
26  * via <code>setViewClass</code>. See UrlBasedViewResolver's javadoc for details.

28  * <p><b>Note:</b> When chaining ViewResolvers, a FreeMarkerViewResolver always
29  * needs to be last, as it will attempt to resolve any view name, no matter
30  * whether the underlying resource actually exists.
