java獲取sid

sid存在cookie裏面所以java代碼直接從cookie中讀取就可以了

  String sid = "";
           HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
           javax.servlet.http.Cookie[] cookies = request.getCookies();
           if (null != cookies) {
               for (javax.servlet.http.Cookie cookie : cookies) {
                   if("sid".equals(cookie.getName())){
                       sid = cookie.getValue();

                   }
               }
           }
