## org.springframework.web.servlet.mvc.annotation
Interface ModelAndViewResolver

    public interface ModelAndViewResolver

SPI for resolving custom return values from a specific handler method. Typically implemented to detect special return types, resolving well-known result values for them.

A typical implementation could look like as follows:

     public class MyModelAndViewResolver implements ModelAndViewResolver {

       public ModelAndView resolveModelAndView(Method handlerMethod,
                                            Class handlerType,
                                            Object returnValue,
                                            ExtendedModelMap implicitModel,
                                            NativeWebRequest webRequest) {
         if (returnValue instanceof MySpecialRetVal.class)) {
           return new MySpecialRetVal(returnValue);
         }
         return UNRESOLVED;
       }
     }
