Question

我正在尝试在登录后在响应中设置cookie，我想在每个其他的api调用中读取该cookie。我尝试了以下代码，但是我没有得到cookie的值..请帮助我。。提前谢谢..

@RequestMapping(value = "/login", method = RequestMethod.POST, consumes = "text/plain")
public String setCookie(HttpServletRequest request, HttpServletResponse response) throws JsonParseException, JsonMappingException, IOException, ServiceException
{
   response.addCookie(new Cookie("token", generateToken()));        
   return "login success";  
}

@RequestMapping(value = "/getResource", method = RequestMethod.POST, consumes = "text/plain")
public String getCookie(HttpServletRequest request, HttpServletResponse response) throws JsonParseException, JsonMappingException, IOException, ServiceException
{
    Cookie[] cookies = request.getCookies();
    if (cookies != null) {
        Arrays.stream(cookies)
              .forEach(c -> System.out.println(c.getName() + "=" + c.getValue()));
    }   
    return "resource list";
}

设置cookie：

Cookie cookie= new Cookie("userName", authentication.getName());
        response.addCookie(cookie);

使用Cookie值：

public String hello(Model model, HttpServletRequest request, HttpServletResponse response,@CookieValue("userName") String usernameCookie) {
console.log(usernameCookie);
}

希望这会有所帮助
