我正在尝试运行下面的元素，但我在使用文档模式的 Internet Explorer 9 上遇到一个“错误”:IE9 标准。它只是不加载 css。
在 Chrome、Firefox、IE 7 和 IE8、IE 9 与 IE8 标准/IE7 标准中运行正常。
我可以做些什么来修复这个“错误”？？？

/**
* Custom JSF ResourceHandler.
*
* This handler bridges between Spring MVC and JSF managed resources. The handler takes
* care of the case when a JSF facelet is used as a view by a Spring MVC Controller and the
* view uses components like h:outputScript and h:outputStylesheet by correctly pointing the
* resource URLs generated to the JSF resource handler.
*
* The reason this custom handler wrapper is needed is because the JSF internal logic assumes
* that the request URL for the current page/view is a JSF url. If it is a Spring MVC request, JSF
* will create URLs that incorrectly includes the Spring controller context.
*
* This handler will strip out the Spring context for the URL and add the ".jsf" suffix, so the
* resource request will be routed to the FacesServlet with a correct resource context (assuming the
* faces servlet is mapped to the *.jsf pattern).
*

最佳答案
IE9 标准模式只接受 Content-Type: text/css 作为 CSS 资源。如果返回另一种内容类型，IE9 将完全忽略整个 CSS 资源。
您需要绝对确保您的自定义资源处理程序设置了正确的内容类型 header 。我不知道 Spring 如何在这里发挥作用，也不知道自定义资源处理程序在此构造中究竟有何意义，但默认情况下，内容类型是根据文件扩展名设置的。至少，您需要确保 CustomResource 的 Resource#getContentType() 方法返回 text/css。
关于java - 使用 Spring/JSF 查看不加载 CSS，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13161831/
