<shiro:authenticated> 登录之后

<shiro:guest> 用户在没有RememberMe时
<shiro:user> 用户在RememberMe时
<shiro:hasAnyRoles name="abc,123" > 在有abc或者123角色时
<shiro:hasRole name="abc"> 拥有角色abc
<shiro:lacksRole name="abc"> 没有角色abc
<shiro:hasPermission name="abc"> 拥有权限abc
<shiro:lacksPermission name="abc"> 没有权限abc
<shiro:principal> 显示用户登录名

--(1)认证过滤器
anon              匿名过滤器
authc             需要认证
authcBasic     表示httpBasic认证  
user               表示必须存在用户,当登入操作时不做检查

--(2)授权过滤器
roles            /admins/user/**=authc,roles[admin] (必须认证过，并拥有admin 角色)
perms
port
rest
ssl 

--(3) shiro 登录退出
shiro 内置的logout 过滤器（先配置logout，再在过滤器链中配置）
<bean id="logout" class="org.apache.shiro.web.filter.authc.LogoutFilter"> 
        <property name="redirectUrl" value="/loginform" /> 
</bean>   
filterChainDefinitions 配置  /logout = logout 

--(4) 关于登录过滤器的配置
通常将登录请求和使用的资源(js.css等)放开设置为anon,将其他的所有资源/** 设置为authc

--(5)关于Session 失效的问题
每次请求都会经过过滤器链的过滤，对于authc的资源，如果登录失效，自动返回到默认登录首页 配置的loginUrl 中；
或者可以自定义个session 拦截的过滤器放入shiro 的过滤器链
