public abstract class AbstractWebScriptViewResolver extends org.springframework.web.servlet.view.UrlBasedViewResolver
Base View Resolver class providing an improved caching strategy over the basic SpringMVC UrlBasedViewResolver. Removes the need to synchronize on the view cache object for each lookup, also caches "null" view lookups which in reality happen more often than not for most view resolvers.
