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;
     }
 }
