Shiro標簽使用實例

please prefix 一個 tag lai efi asa pla nta

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標簽庫前,首先需要在JSP引入shiro標簽:
<%@ taglib prefix="shiro" uri="http://shiro.apache.org/tags" %>
  • guest標簽 :驗證當前用戶是否為“訪客”,即未認證(包含未記住)的用戶

    <shiro:guest> 
     
    Hi there!  Please 
    <a href="login.jsp">Login</a> or <a href="signup.jsp">Signup</a> today! </shiro:guest>

  • user標簽 :認證通過或已記住的用戶
    <shiro:user> 
     
        Welcome back John!  Not John? Click <a href="login.jsp">here<a> to login. 
     
    </shiro:user>

  • authenticated標簽 :已認證通過的用戶。不包含已記住的用戶,這是與user標簽的區別所在
    <
    shiro:authenticated> <a href="updateAccount.jsp">Update your contact information</a>. </shiro:authenticated>

  • notAuthenticated標簽 :未認證通過用戶,與authenticated標簽相對應。與guest標簽的區別是,該標簽包含已記住用戶
    <shiro:notAuthenticated> 
     
        Please <a href="login.jsp">login</a>
    in order to update your credit card information. </shiro:notAuthenticated>

  • principal 標簽 :輸出當前用戶信息,通常為登錄帳號信息
    Hello, <shiro:principal/>, how are you today?

  • hasRole標簽 :驗證當前用戶是否屬於該角色
    <shiro:hasRole name="administrator"> 
     
        <a href="admin.jsp">Administer the system</a> 
     
    </shiro:hasRole>

  • lacksRole標簽 :與hasRole標簽邏輯相反,當用戶不屬於該角色時驗證通過
    <shiro:lacksRole name="administrator"> 
     
        Sorry, you are not allowed to administer the system. 
     
    </shiro:lacksRole>

  • hasAnyRole標簽 :驗證當前用戶是否屬於以下任意一個角色
    <shiro:hasAnyRoles name="developer, project manager, administrator"> 
     
        You are either a developer, project manager, or administrator. 
     
    </shiro:lacksRole>

  • hasPermission標簽 :驗證當前用戶是否擁有指定權限
    <shiro:hasPermission name="user:create"> 
     
        <a href="createUser.jsp">Create a new User</a> 
     
    </shiro:hasPermission>

  • lacksPermission標簽 :與hasPermission標簽邏輯相反,當前用戶沒有制定權限時,驗證通過
    <shiro:hasPermission name="user:create"> 
     
        <a href="createUser.jsp">Create a new User</a> 
     
    </shiro:hasPermission>
