Re: [Springframework-developer] successView changes

[<jue...@we...>]

The "redirect:" prefix is checked in UrlBasedViewResolver, so all its =
subclasses (InternalResourceViewResolver, VelocityViewResolver, =
FreeMarkerViewResolver) will recognize it.

Actually I just have a
org.springframework.web.servlet.view.velocity.VelocityViewResolver right
now.

No. I am assuming right now you are using InternalResourceViewResolver.
All you would need to do is define the view name literal (which should =
still
be in the config, not hardcoded in the controller) as

redirect:viewFoo.html

in this particular case. Then the controller can just do

return new ModelAndView(getSuccessView(), "id", theId));

InternalResourceViewResolver (or rather its superclass
UrlBasedViewResolver) will see the 'redirect:' prefix, and create and =
use a
RedirectView itself. So the nice thing is that that controller no longer
needs to know that there is a redirect. Now keep in mind that there's
limitations to the opacity though, in terms of whether control will go =
to an
internal view or to a redirect, since on a redirect all the model params
need to go on the URL. So same as before, you can't stick in any =
arbitrary
complex property into the model and expect to be able to do a =
redirect...
