如何确保用户在查看任何页面之前已登录?JSF.

Question

我创建了一个项目，我希望确保用户已登录并使用我的ldap服务器进行身份验证，我将如何做到这一点，

 |-- META-INF
 |-- WEB-INF
 |-- resources
 |    |-- css
 |    |    `-- style.css
 |
 |-- upload
 |    |-- uploadText.xhtml
 |
 |-- index.xhtml
 |-- SubmittedText.xhtml
 |-- etc.xhtml

我想保护除资源文件夹之外的所有内容

这是我目前的网络.xml

Answer 1

您的<security-constraint>缺少<auth-constraint>。没有身份验证约束的安全约束基本上是公共资源。例如，如果要限制所有角色，则应将以下身份验证约束置于安全约束中。

<auth-constraint>
    <role-name>*</role-name>
</auth-constraint> 

总而言之，如果您想限制/*期望的所有内容 /javax.faces.resource/* ，那么您应该具有以下安全约束，正好按照web.xml的顺序排列：

<security-constraint>
    <web-resource-collection>
        <web-resource-name>Restircted resources</web-resource-name>
        <url-pattern>/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
        <role-name>*</role-name>
    </auth-constraint> 
</security-constraint>
<security-constraint>
    <web-resource-collection>
        <web-resource-name>Allowed resources</web-resource-name>
        <url-pattern>/javax.faces.resource/*</url-pattern>
    </web-resource-collection>
    <!-- No Auth Contraint! -->
</security-constraint>

您的HTTP方法限制列表有些荒谬，只是省略它。默认情况下，它已经应用于每个 HTTP 方法。
