不支持的视图类型 /WEB-INF/index.xhtml 仅此 FlowViewResolver 实现支持的类型是 [.jsp] 和 [.jspx]

Question

Spring-webflow 配置和视图重定向存在问题。

登录后，您应该进入配置的主页，但您会被重定向到错误页面。

查看log trace，确认登录中提交时，重定向到对应的视图，但是控制视图的spring组件出现错误，只允许jsp和jspx。

我们正在使用 Spring-webflow 2.4.1、Spring-mvc 3.1.4、jsf 2.2 和 primefaces 4.0。

我们一直在验证如何使用 xml 执行此操作的不同方法，因为它是一个旧应用程序，我们正在做的是从 ant 重构为 maven，以便继续进行所需的修改。

产生的错误如下：
