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;
   }
 }
