Question

In my controller I’m using

return new ModelAndView( "redirect:new_page" );

now I changed Spring version from 3.0.6 to 3.1.2 and I found that it’s not working in new version.

My Controller is defined like

@Controller
@RequestMapping(value = "/test")
public class MyController {

I tried to use

• "redirect:/new_page"
• "redirect:/test/new_page"
• "redirect:./new_page"

and nothing helped, any idea?

So the problem you had is using Object as return type, which, accoring to Spring MVC reference manual, isn’t dispatched as view name or ModelAndView:

• Any other return type is considered to be a single model attribute to
  be exposed to the view, using the attribute name specified through
  @ModelAttribute at the method level (or the default attribute name
  based on the return type class name). The model is implicitly enriched
  with command objects and the results of @ModelAttribute annotated
  reference data accessor methods.

I guess you used some undocumented / internal part of Spring MVC, which implementation changed in new release.
