更新
我试图在我的 spring3 应用程序中使用 JSF 复合组件。做一个简单的测试
/test（映射到视图视图\test.xhtml）
我收到以下错误：

如果我删除复合组件，此错误就会消失

/**
* 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).
*
