在使用Shiro标签库前,首先需要在JSP引入shiro标签:
1
|
|
1、介绍Shiro的标签guest标签 :验证当前用户是否为“访客”,即未认证(包含未记住)的用户。

|
<shiro:guest> Hi there! Please <a href= "login.jsp" >Login</a> or <a href= "signup.jsp" >Signup</a> today!
</shiro:guest> |
2、user标签 :认证通过或已记住的用户。

|
<shiro:user> Welcome back John! Not John? Click <a href= "login.jsp" >here<a> to login.
</shiro:user> |
3、authenticated标签 :已认证通过的用户。不包含已记住的用户,这是与user标签的区别所在。

<shiro:authenticated> <a href= "updateAccount.jsp" >Update your contact information</a>.
</shiro:authenticated> |
4、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> |
5、principal 标签 :输出当前用户信息,通常为登录帐号信息。
1
|
Hello, <shiro:principal/>, how are you today? |
6、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> |
7、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> |
8、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" >

9、hasPermission标签 :验证当前用户是否拥有指定权限。

<shiro:hasPermission name= "user:create" >
<a href= "createUser.jsp" >Create a new User</a>
</shiro:hasPermission> |
10、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。
