HTTP 状态 403 - 对所请求资源的访问已被拒绝（CSS 被阻止？）

我一直在努力保护我的项目。我有一个使用 LDAP 服务器进行身份验证的登录页面，如果不正确，它会显示一个错误页面等。我现在刚刚添加

<auth-constraint> <!-- Currently causing a 403, looks like stoping .css files --> 
    <role-name>*</role-name>
</auth-constraint>

to my web.xml，以确保用户在可以查看任何页面之前经过身份验证，但是它似乎阻止了我的 .css 文件，我认为现在登录页面根本不显示任何 css，并且只是白色基本的，当我按提交我得到：

• http://localhost:8080/fileuploadWithPreview/javax.faces.resource/theme.css.xhtml?ln=primefaces-aristo http://localhost:8080/fileuploadWithPreview/javax.faces.resource/theme.css.xhtml?ln=primefaces-aristo

出现此错误：

HTTP 状态 403 - 对请求的资源的访问已被拒绝

基本上，是什么阻止了我的 css 文件以及如何允许它？

您的安全限制还会阻止对 CSS 文件的请求（基本上，它会阻止一切与指定的 URL 模式匹配/*期望指定的登录页面）。您需要添加另一个安全约束，该约束应允许对 JSF 资源的请求。关键是省略身份验证约束，使每个人都可以访问这些资源。

<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>
