In spring mvc 3, how to write a cookie while returning a ModelAndView?

Question

My controller method is returning a ModelAndView, but there is also a requirement to write a cookie back to client. Is it possible to do it in Spring? Thanks. <

RustyX's solution in Java 8:

@Component
    public class ModelCookieInterceptor extends HandlerInterceptorAdapter {

        @Override
        public void postHandle(HttpServletRequest req, HttpServletResponse res, Object handler, ModelAndView modelAndView) throws Exception{
            if (modelAndView != null) {
                modelAndView.getModel().values().stream()
                    .filter(c -> c instanceof Cookie)
                    .map(c -> (Cookie) c)
                    .forEach(res::addCookie);
            }
        }
    }
