Question

在webflow-config.xml中的Maven项目中我在webflow-config.xml

中遇到以下错误

Error occured processing XML 'Could not initialize class org.springframework.faces.webflow.JsfRuntimeInformation'.

这是我的pom.xml：

此错误与行<faces:resources />

有关

我是这个主题的新手，我不知道该怎么做。

我解决了这个问题。弹簧面2.4.1。 <faces:resources />不是必需的。我的webflow-config.xml和application-context.xml配置错误。弹簧面2.4.1的配置配置，你可以在这里找到：
