Question

@RequestMapping(value = "/login", method = RequestMethod.POST)
    public String login(HttpServletResponse response, Model modelAndView, @RequestParam String email, @RequestParam String password, @RequestParam(required = false) String redirect) {
        LoginDTO loginDTO = account.doLogin(email, password);
        if (loginDTO.getLoginMGS() == LoginStatus.LOGGED_IN) {
            Cookie cookie = new Cookie("token", loginDTO.getToken());
            cookie.setMaxAge(24 * 60 * 60);
            response.addCookie(cookie);
            modelAndView.addAttribute("result", "Login successful");
            if (redirect != null && !redirect.equals("")) {
                return "redirect:" + redirect;
            }
        } else {
            modelAndView.addAttribute("result", "Password not same");
        }
        return "login";
    }

当我尝试像这样获取cookie时

private String getToken(Cookie[] cookies) {
        for (Cookie cookie : cookies) {
            System.out.println("cookie name " + cookie.getName() + " " + cookie.getValue());
            if (cookie.getName().equals("token")) {
                return cookie.getValue();
            }
        }
        return null;
    }

Answer 1

如果要在两次请求之间访问Cookie，则必须指定路径details

Cookie cookie = new Cookie("token", loginDTO.getToken());
cookie.setMaxAge(24 * 60 * 60);
cookie.setPath(path);
response.addCookie(cookie);

Answer 2

在我的情况下，未创建cookie是因为当我在没有https的本地主机上时cookie是“安全的”

cookie.setSecure(true)

Cookie没有设置在spring boot mvc中
