jsf - 将 JSF 1.2 迁移到 2.x 导致 com.sun.faces.config.InitFacesContext.cleanupInitMaps 处的 java.lang.NullPointerException

Question

我正在将 JSF 1.2 应用程序迁移到 JSF 2.x。我的应用程序使用以下 API：

• maven-jetty-plugin（版本 6.1.10）
• maven-compiler-plugin (版本 2.3.1)
• myfaces-api & -impl (版本 1.2.7)
• jsf-facelets（版本 1.1.14）
• Richfaces（版本 3.3.3）
• javax servlet jstl（1.2 版）
• javax servlet-api（2.5 版）
• 以及其他一些插件。

我更新了faces-config.xml文件中的版本并删除了 Facelets 1.1.14 库并用 JSF 2.x 库替换了 MyFaces 1.2，但是该应用程序无法正常工作。它引发了以下异常：

java.lang.ClassNotFoundException：org.apache.myfaces.webapp.StartupServletContextListener

正如包名所暗示的，这是一个 MyFaces 特定的类，当您将 MyFaces 1.2 替换为 Mojarra 2.0 而不是 MyFaces 2.0 时，它显然不再可用。

此类通常<listener>在 webapp 的web.xml. 如果<listener>从 中删除整个条目web.xml，则此异常应该消失。您通常不需要自己明确声明，因为它已经在 TLD 文件中注册。但是，Jetty 有一些错误，您需要自己显式注册它。对于 Mojarra，这将是：

<listener>
   <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener> 

另一种方法是升级到 MyFaces 2.0 而不是 Mojarra 2.0。那里存在相同的侦听器类。

也可以看看：

• Mojarra 和 MyFaces 之间的区别
• 找不到工厂：javax.faces.context.FacesContextFactory
