There is no session with id [xxx]

报错为：org.apache.shiro.session.UnknownSessionException: There is no session with id解决办法如下：
ShiroConfig类配置以下，将“sessionManager”方法中的setSessionIdCookie赋值改为以下

    sessionManager.setSessionIdCookie(sessionIdCookie());

    private SimpleCookie sessionIdCookie() {SimpleCookie cookie = new SimpleCookie();Long sessionIdL = new Long(System.currentTimeMillis());String sessionId = sessionIdL.toString();cookie.setName(sessionId);cookie.setHttpOnly(true);cookie.setMaxAge(30 * 60 * 1000);return cookie;}
