Posted by – November 9, 2008

Yesterday I wrote a small set of EL functions to use with spring security, now I can get easy access to spring security roles and authentication info as well.

Here’s an example of how bodyguard can be used in your facelets code:

   <!-- Display logged message if the user is authenticated -->
   <t:div rendered="#{bg:isAuthenticated()}">
       <h:outputText rendered="#{bg:remoteUser()}" value="Logged!"/>
   </t:div>

   <!-- Display a message indicating if the user is a user or admin -->
   <t:div rendered="#{bg:isUserInAnyRoles('ROLE_USER,ROLE_ADMIN')}">
       <h:outputText
         value="The user #{bg:remoteUser()} is a user or admin."/>
   </t:div>

   <!-- Display a message indicating if the user isn't a user or admin -->
   <t:div rendered="#{bg:isUserNotInRoles('ROLE_USER,ROLE_ADMIN')}">
       <h:outputText
         value="The user #{bg:remoteUser()} isn't a user or admin."/>
   </t:div>

   <!-- Display a message indicating if the user is a user and admin -->
   <t:div rendered="#{bg:isUserInAllRoles('ROLE_USER,ROLE_ADMIN')}">
       <h:outputText
          value="The user #{bg:remoteUser()} is a user and admin."/>
   </t:div>
 </body>
