java - JSF:/WEB-INF/*/javax.faces.resource/theme.xhtml 在ExternalContext 中未找到资源(Primeface 的资源 URI 有星号)

Question

使用 JSF、Spring、Spring WebFlow、PrimeFaces。我正在尝试打开简单的“hello world”页面。页面本身已打开，但抛出异常，无法包含 Primeface 的主题:

页面正在使用这样的 CSS 链接生成，其中还包含星号登录 href:

<link type="text/css" rel="stylesheet" href="/spring/*/javax.faces.resource/theme.css?ln=primefaces-aristo">

不带星号的 CSS 本身可以通过以下链接正确打开:

.../spring/javax.faces.resource/theme.css?ln=primefaces-aristo

Answer 1

解决了将 url-pattern 更新为以下问题:

<servlet-mapping>
        <servlet-name>springFlowApplication</servlet-name>
        <url-pattern>/app/*</url-pattern>
</servlet-mapping>

如果有人能解释为什么需要添加“/app”，那就太好了，因为现在整个 URL 还包含“../app/..”，这看起来不太好看......
