maven - 在 Tomcat 7 中部署的 Myfaces、Facelets、Tomahawk 和 Maven 失败

Question

我很难让战斧运行。不久前，我使用 myfaces hellworld20 原型创建了一个新项目。现在我想用战斧来扩展它。新的 pom.xml 如下所示：

一旦我将所有与 tomahawk 相关的依赖项注释掉，服务器就会正确部署，尽管与 tomahawk 相关的标签似乎不起作用。

如果我不将其注释掉，我会收到如下错误消息：

Schwerwiegend: StandardWrapper.Throwable
java.lang.IllegalStateException: No Factories configured for this Application. This happens if the faces-initialization does not work at all - make sure that you properly include all configuration settings necessary for a basic faces application and that all the necessary libs are included. Also check the logging output of your web application and your container for any exceptions!
If you did that and find nothing, the mistake might be due to the fact that you use some special web-containers which do not support registering context-listeners via TLD files and a context listener is not setup in your web.xml.
A typical config looks like this;
<listener>
  <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
</listener>

我已经搜索了几个小时，现在访问了大量与标签 tomhawk、maven、facelets 相关的页面。但我似乎没有找到解决方案，这就是我在这里问的原因。也许这是微不足道的，甚至可能是显而易见的，但我找不到为什么这不起作用的答案。

Answer 1

我认为这行不通。您不能将 tomahawk-sandbox 1.1.6 与 tomahawk20 1.1.13 一起使用，因为 tomahawk-sandbox 仅适用于 JSF 1.1/1.2。此外，您不需要 com.sun.facelets，因为 JSF 实现，在本例中为 JSF 2.0/2.1 实现（在本例中为 MyFaces Core）在其 jar 中已有 facelets。不要使用 com.google.code.tomahawk，Facelets 支持是很久以前添加到 tomahawk 中的。首先尝试仅添加 tomahawk20 1.1.13，也就是将其添加为依赖项，然后您可以尝试添加沙盒，但请注意沙盒永远不会发布，因此您需要从源代码手动构建它或从快照 repo中获取它。
