spring boot为spring session生成uuid

 

也可以使用session自带的id，这里演示的是使用自定义uuid为session生成的id

    @RequestMapping(value = "/uuid", method = RequestMethod.GET)
    public @ResponseBody
    String uid(HttpSession session) {
        UUID uid = (UUID) session.getAttribute("uuid");
        if (uid == null) {
            uid = UUID.randomUUID();
        }
        log.info("getMaxInactiveInterval = ", session.getMaxInactiveInterval());
        session.setAttribute("uuid", uid);
        return session.getId();
    }
