聊聊Springboot2.x的session和cookie有效期

server.servlet.session.timeout=   # session的有效期，默认为30min
server.servlet.session.cookie.max-age=  #cookie的有效期，默认为-1 即是和浏览器关闭状态有关

    public int test(httpservletRequest request, HttpServletResponse response) {
        int maxInactiveInterval = request.getSession().getMaxInactiveInterval();
        Cookie[] cookies = request.getCookies();
        System.out.println("maxInactiveInterval: " + maxInactiveInterval);
        Cookie cookie = new Cookie("uid","koo");
        cookie.setMaxAge(5);
        response.addCookie(cookie);
        return maxInactiveInterval;
    }

server.servlet.session.timeout=86400
server.servlet.session.cookie.max-age=86400
Cookie cookie = new Cookie(“uid”,“koo”);
cookie.setMaxAge(23*3600);
response.addCookie(cookie);

    HttpSession session = request.getSession(false);
        Object sessionObj = session.getAttribute(LOGIN_NAME);//session为空
        String currentName = null == sessionObj ? null : sessionObj.toString();
        if (StringUtils.isBlank(currentName)) {
            res.setMessage(messageUtil.getMessage("reLogin"));
            res.setStatusCode(StatusCode.RE_LOGIN.getCode());
            return res;
        }
