Chapter 10. Security - JBoss Portal 2.4 Reference Guide 英文版参考指南文档

This section describes how to secure portal objects (portal instances, pages, and portlet instances), using the JBoss Portal *-object.xml descriptor OR portlet-instances.xml descriptor. View the User Guide for information on how to secure objects using the Management Portlet.

Securing portal objects declaratively, is done through the *-object.xml ( Section 6.1.1, “*-object.xml” ), for Portal Instances and Pages, or the portlet-instances.xml ( Section 6.1.2, “portlet-instances.xml” ) for Portlet Instances. The portion you will be adding to each object is denoted by the <security-constraint> tag:

<?xml version="1.0" encoding="UTF-8"?>
<deployments>
   <deployment>
      <if-exists>overwrite</if-exists>
      <parent-ref>default</parent-ref>
      <properties/>
      <page>
         <page-name>MyPage</page-name>
         <window>
            <window-name>HelloWorldPortletPageWindow</window-name>
            <instance-ref>HelloWorldPortletPageInstance</instance-ref>
            <region>center</region>
            <height>0</height>
         </window>
         <security-constraint>
            <policy-permission>
               <unchecked/>
               <action-name>viewrecursive</action-name>
            </policy-permission>
         </security-constraint>
      </page>
   </deployment>
</deployments>
         

A security constraint on an object (our example above, secures a specific portal page), is explained as:

<security-constraint>
   <policy-permission>
      <unchecked/>
      <action-name>viewrecursive</action-name>
   </policy-permission>
</security-constraint>

The security contraint portion is worth taking a look at, in an isolated fashion. It allows you to secure a specific window/page/portal-instance based on a user's role.

Role definition: You must define a role that this security constraint will apply to. Possible values are:

Access Rights: You must define the access rights given to the role defined. Possible values are:
