View Resolving: Implementation Classes
InternalResourceViewResolver
A convenience subclass of UrlBasedViewResolver  that supports InternalResourceView (i.e. Servlets and JSPs), and subclasses such as JstlView and TilesView. The view class for all views generated by this resolver can be specified via setViewClass(..). See the Javadocs for the UrlBasedViewResolver class for details.
BeanNameViewResolver
Simple implementation of ViewResolver that interprets a view name as bean name in the current application context, i.e. in the XML file of the executing DispatcherServlet. This resolver can be handy for small applications, keeping all definitions ranging from controllers to views in the same place.
UrlBasedViewResolver
A simple implementation of the ViewResolver  interface that effects the direct resolution of symbolic view names to URLs, without an explicit mapping definition. This is appropriate if your symbolic names match the names of your view resources in a straightforward manner, without the need for arbitrary mappings.
ResourceBundleViewResolver
An implementation of ViewResolver  that uses bean definitions in a ResourceBundle, specified by the bundle basename. The bundle is typically defined in a properties file, located in the classpath. The default file name is views.properties.
XmlViewResolver
An implementation of ViewResolver  that accepts a configuration file written in XML with the same DTD as Spring's XML bean factories. The default configuration file is /WEB-INF/views.xml.
AbstractCachingViewResolver
An abstract view resolver which takes care of caching views. Often views need preparation before they can be used, extending this view resolver provides caching of views.
VelocityViewResolver / FreeMarkerViewResolver
A convenience subclass of UrlBasedViewResolver that supports VelocityView (i.e. Velocity templates) or FreeMarkerView respectively and custom subclasses of them.
