将 Spring 与 JSF2 集成

Question

我与 jsf2 spring 和 hibernate 一起从事一个项目。 当我想将 jsf2 与 spring 集成时，在tomcat7 中启动我的 JSF 时出现此错误。我有罐子 myfaces-impl & api。我在网上搜索，但直到现在都没有找到解决办法。

Answer 1

您需要添加jsf2 库。如果您已添加它，则它不在您的类路径中。

Answer 2

在 JSF 2 中使用旧的 facelets jar 是没有意义的，因为实现捆绑了 facelets VDL。相反，似乎在 JSF 2 应用程序中使用了一些 JSF 1.2 库，这是不对的。如果您使用的是 JSF 2，只需更新您的库即可。
