Cookie没有在我的Spring控制器中设置

Question

@Override
@SuppressWarnings("unchecked")
protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception {


         response.addCookie(new Cookie("COOKIENAME", "The cookie's value"));
         //...
         request.getSession().setAttribute("userName", userName);

         ModelAndView model = new ModelAndView("main-decorator");        
         model.getModel().put("versionInfo", getVersionInfo());
         //...
         return model;
}
