　　用户没有身份验证时显示相应信息，即游客访问信息。
user标签
　　<shiro:user>　　
　　</shiro:user>
　　用户已经身份验证/记住我登录后显示相应的信息。
authenticated标签
　　<shiro:authenticated>　　
　　</shiro:authenticated>
　　用户已经身份验证通过，即Subject.login登录成功，不是记住我登录的。
notAuthenticated标签
　　<shiro:notAuthenticated>
　　
　　</shiro:notAuthenticated>
　　用户已经身份验证通过，即没有调用Subject.login进行登录，包括记住我自动登录的也属于未进行身份验证。
