Shiro标签使用实例

Posted 2020-10-15

shiro.xml

/admin/repairType/index = roles["ROLE_ADMIN"]
/admin/user=roles["ROLE_ADMIN"]
/admin/complaint/list= roles["ROLE_SERVICE,ROLE_ADMIN"]

在使用Shiro标签库前，首先需要在JSP引入shiro标签：
<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>

• 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>

   

• 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>

   

• 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>

   

• 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指定权限

  <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>
