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;
}

To access HttpRequest from controller you just need to define HttpServletRequest and HttpServletResponse as parameters in a function signature of your Controller. by doing this you allowing Spring MVC to pass these objects to you controller method.
By using @RequestBody annotation you will get your values mapped with the model you created in your system for handling any specific call. While by using @ResponseBody you can send anything back to the place from where the request was generated. Both things will be mapped easily without writing any custom parser etc.
The @ResponseBody annotation tells a controller that the object returned is automatically serialized into JSON and passed back into the HttpResponse object. When you use the @ResponseBody annotation on a method, Spring converts the return value and writes it to the HTTP response automatically.
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;
}
