public class ModelAndViewMethodReturnValueHandler
extends java.lang.Object
implements org.springframework.web.method.support.HandlerMethodReturnValueHandler
ModelAndView
copying view and model
information to the ModelAndViewContainer
.
If the return value is null
, the
ModelAndViewContainer.setRequestHandled(boolean)
flag is set to
true
to indicate the request was handled directly.
A ModelAndView
return type has a set purpose. Therefore this
handler should be configured ahead of handlers that support any return
value type annotated with @ModelAttribute
or @ResponseBody
to ensure they don't take over.

There must be a custom View
that recognizes the prefix as well.
