 * Implementation of {@link org.springframework.web.servlet.HandlerMapping} that
 * follows a simple convention for generating URL path mappings from the <i>bean names
 * of registered {@link org.springframework.web.servlet.mvc.Controller} and
 * {@link org.springframework.web.servlet.mvc.throwaway.ThrowawayController} beans
 * as well as <code>@Controller annotated beans.
 * <p>This is similar to {@link org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping}
 * but doesn't expect bean names to follow the URL convention: It turns plain bean names
 * into URLs by prepending a slash and optionally applying a specified prefix and/or suffix.
 * However, it only does so for well-known {@link #isControllerType controller types},
 * as listed above (analogous to {@link ControllerClassNameHandlerMapping}).
