301 status redirection in Spring MVC 4 without ModelAndView

I am trying to redirect from 301 Status Code(you know that I want to be SEO friendly, etc.).

I use InternalResourceViewResolver, so I wanted to use some kind of code similar to return "redirect:http://google.com"in my controller. This, although it would send302 Status Code

I tried to use HttpServletResponseto set the title

@RequestMapping(value="/url/{seo}", method = RequestMethod.GET)
public String detail(@PathVariable String seo, HttpServletResponse response){
    response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
    return "redirect:http://google.com";
}

It returns anyway 302.

After checking the documentation and Google results, I got the following:

@RequestMapping(value="/url/{seo}", method = RequestMethod.GET)
public ModelAndView detail(@PathVariable String seo){
    RedirectView rv = new RedirectView();
    rv.setStatusCode(HttpStatus.MOVED_PERMANENTLY);
    rv.setUrl("http://google.com");
    ModelAndView mv = new ModelAndView(rv);
    return mv;
}

It works fine and, as expected, returns code 301

I would like to achieve this without using ModelAndView (maybe this is fine, though). Is it possible?

If you already returned ModelAndView and do not want to use HttpServletResponse, you can use this snippet:

        RedirectView rv = new RedirectView("redirect:" + myNewURI);
        rv.setStatusCode(HttpStatus.MOVED_PERMANENTLY);
        return new ModelAndView(rv);
