HandlerMapping
Maps incoming requests to handlers and a list of pre- and post-processors (handler interceptors) based on some criteria the details of which vary by HandlerMapping implementation. The most popular implementation supports annotated controllers but other implementations exists as well.
HandlerAdapter
Helps the DispatcherServlet to invoke a handler mapped to a request regardless of the handler is actually invoked. For example, invoking an annotated controller requires resolving various annotations. Thus the main purpose of a HandlerAdapter is to shield the DispatcherServlet from such details.
HandlerExceptionResolver
Maps exceptions to views also allowing for more complex exception handling code.
ViewResolver
Resolves logical String-based view names to actual View types.
LocaleResolver & LocaleContextResolver
Resolves the locale a client is using and possibly their time zone, in order to be able to offer internationalized views
ThemeResolver
Resolves themes your web application can use, for example, to offer personalized layouts
MultipartResolver
Parses multi-part requests for example to support processing file uploads from HTML forms.
FlashMapManager
Stores and retrieves the "input" and the "output" FlashMap that can be used to pass attributes from one request to another, usually across a redirect.

ViewResolver Description
AbstractCachingViewResolver
Abstract view resolver that caches views. Often views need preparation before they can be used; extending this view resolver provides caching.
XmlViewResolver
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.
ResourceBundleViewResolver
Implementation of ViewResolver that uses bean definitions in a ResourceBundle, specified by the bundle base name. Typically you define the bundle in a properties file, located in the classpath. The default file name is views.properties.
UrlBasedViewResolver
Simple implementation of the ViewResolver interface that effects the direct resolution of logical view names to URLs, without an explicit mapping definition. This is appropriate if your logical names match the names of your view resources in a straightforward manner, without the need for arbitrary mappings.
InternalResourceViewResolver
Convenient subclass of UrlBasedViewResolver that supports InternalResourceView (in effect, Servlets and JSPs) and subclasses such as JstlView and TilesView. You can specify the view class for all views generated by this resolver by using setViewClass(..). See the UrlBasedViewResolver javadocs for details.
VelocityViewResolver / FreeMarkerViewResolver
Convenient subclass of UrlBasedViewResolver that supports VelocityView (in effect, Velocity templates) or FreeMarkerView ,respectively, and custom subclasses of them.
ContentNegotiatingViewResolver
Implementation of the ViewResolver interface that resolves a view based on the request file name or Accept header. See Section 21.5.4, “ContentNegotiatingViewResolver”.
