java.lang.Objectorg.springframework.web.method.annotation.MapMethodProcessor
public class MapMethodProcessor
Resolves Map method arguments and handles Map return values.
A Map return value can be interpreted in more than one ways depending
on the presence of annotations like @ModelAttribute or
@ResponseBody. Therefore this handler should be configured after
the handlers that support these annotations.

void |
handleReturnValue(Object returnValue,
MethodParameter returnType,
ModelAndViewContainer mavContainer,
NativeWebRequest webRequest)
Handle the given return value by adding attributes to the model and setting a view or setting the ModelAndViewContainer.setRequestHandled(boolean) flag to true
to indicate the response has been handled directly. |
