<shiro:authenticated>
<a href="updateAccount.jsp">Update your contact information</a>.
</shiro:authenticated>
notAuthenticated标签
未认证通过用户,与authenticated标签相对应。与guest标签的区别是,该标签包含已记住用户。
<shiro:notAuthenticated>
Please <a href="login.jsp">login</a> in order to update your credit card information.
</shiro:notAuthenticated>
principal 标签
输出当前用户信息,通常为登录帐号信息
Hello, <shiro:principal/>, how are you today?
hasRole标签
验证当前用户是否属于该角色
<shiro:hasRole name="administrator">
<a href="admin.jsp">Administer the system</a>
</shiro:hasRole>
lacksRole标签
与hasRole标签逻辑相反,当用户不属于该角色时验证通过
<shiro:lacksRole name="administrator">
Sorry, you are not allowed to administer the system.
</shiro:lacksRole>
hasAnyRole标签
验证当前用户是否属于以下任意一个角色。
<shiro:hasAnyRoles name="developer, project manager, administrator">
You are either a developer, project manager, or administrator.
</shiro:lacksRole>
hasPermission标签
验证当前用户是否拥有制定权限
<shiro:hasPermission name="user:create">
<a href="createUser.jsp">Create a new User</a>
</shiro:hasPermission>
lacksPermission标签
与hasPermission标签逻辑相反,当前用户没有制定权限时,验证通过
<shiro:hasPermission name="user:create">
<a href="createUser.jsp">Create a new User</a>
</shiro:hasPermission>
三、Shiro授权的内部处理机制

1、在应用程序中调用授权验证方法(Subject的isPermitted*或hasRole*等)
2、Sbuject的实例通常是DelegatingSubject类(或子类)的实例对象,在认证开始时,会委托应用程序设置的securityManager实例调用相应的isPermitted*或hasRole*方法。
3、接下来SecurityManager会委托内置的Authorizer的实例(默认是ModularRealmAuthorizer 类的实例,类似认证实例,它同样支持一个或多个Realm实例认证)调用相应的授权方法。
