Spring controller get request/response

How do I get the request/response that I can setcookie? Additionally, at the end of this method, how can I can redirect to another page?

@RequestMapping(value = "/dosomething", method = RequestMethod.GET)
public RETURNREDIRECTOBJ dosomething() throws IOException {
    ....
    return returnredirectpagejsp;
}

You could also use this way

@RequestMapping(value = "/url", method = RequestMethod.GET)
    public String method(HttpServletRequest request, HttpServletResponse response){
        Cookie newCookie = new Cookie("key", "value");
        response.addCookie(newCookie);
        return "redirect:/newurl";
    }

You can also simply @Autowire. For example:

@Autowired 
private HttpServletRequest request;

Though HttpServletRequest is request-scoped bean, it does not require your controller to be request scoped, as for HttpServletRequest Spring will generate a proxy HttpServletRequest which is aware how to get the actual instance of request.

How about this:

@RequestMapping(value = "/dosomething", method = RequestMethod.GET)
public ModelAndView dosomething(HttpServletRequest request, HttpServletResponse response)  throws IOException {
    // setup your Cookie here
    response.setCookie(cookie)
    ModelAndView mav = new ModelAndView();
    mav.setViewName("redirect:/other-page");

    return mav;
}

  1. Just pass it as argument: public String doSomething(HttpServletRequest request). You can pass both the request and response, or each of them individually.
  2. return the String "redirect:/viewname" (most often without the .jsp suffix)

For both questions, check the documentation, section "15.3.2.3 Supported handler method arguments and return types"
