【问题描述】：

我有小问题

为什么有时UI在page.jsf中，出现有时不出现... 而且我没有收到任何错误

我正在使用：

netbeans 6.9.1 JSF 2.0 素面 3.1.1 springframework 3.0.2 glassfish 服务器 3.0

我的意思是：我无法在 jsf.page web.xml

中加载我的 primefaces、javascript 和 css

谢谢，需要你的帮助和建议 agungdmt

【问题讨论】：

这个问题太笼统了。请把问题隔离成尽可能小的代码段，我们基本上可以复制'n'paste'n'run到一个空白的游乐场项目中自己查看，以便我们指出错误。

hii balusC，抱歉，请查看更新

对不起，春天已经超越了我。如果问题出在 Spring 配置中，我不会感到惊讶。您至少需要确保 /javax.faces.resource/* 请求已通过。它们被<h:outputStylesheet>、<h:outputScript> 和<h:graphicImage> 使用。

好的谢谢建议 BalusC ...:D

【参考方案1】：

我可以解决它，只需远程符号 [*] 来自

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

到

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/</url-pattern>
</filter-mapping>

它的工作原理

【讨论】：

这种方式过滤器仅在默认 servlet 运行时运行，因此不会在任何其他 servlet（如FacesServlet）运行时运行。您在 JSF 页面上的安全性不是这样禁用了吗？
