使用Spring / JSF查看不加载CSS

标签： java css spring internet-explorer jsf

我正在尝试运行下面的项目，但我在Internet Explorer 9上遇到了文档模式：IE9标准的“错误”。它只是不加载CSS。

在Chrome，Firefox，IE 7和IE8，带有IE8标准/ IE7标准的IE 9中运行正常。

我可以做些什么来解决这个“错误”???

的web.xml

/**
 * 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). 
 *

答案 0 :(得分：1)

IE9标准模式仅接受Content-Type: text/css的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。

您需要确保自定义资源处理程序设置正确的内容类型标头。我不知道Spring如何扮演这里的角色以及该自定义资源处理程序在这个构造中的确切含义，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Resource#getContentType()的{​​{1}}方法返回CustomResource。
