Spring MVC 3 mvc-basic示例项目生成@Controller错误

Question

在不成功地尝试从头开始设置一个Spring MVC 3项目（得到各种错误）后，我决定结账其中一个示例项目，看看它们是如何区别的，以弄清楚我做错了什么。我已经从 https://src.springframework.org/svn/spring-samples/mvc-basic/trunk/ 中删除了mvc-basic项目并在eclipse中打开了。该项目显然缺少对Spring Framemework的引用，还需要 apache.commons.logging 和 jstl 。我下载了这些并添加了它们。我上传了整个项目树结构的图像（在帖子的底部）。当我运行应用程序时，我得到以下警告，尽管是一个警告似乎阻止应用程序正常运行：

WARNING: Failed to classload type while reading annotation metadata. This is a non-fatal error, but certain annotation metadata may be unavailable.
java.lang.ClassNotFoundException: Controller

我假设它抱怨装饰AccountController类的 @Controller 注释（org.springframework.stereotype.Controller）。但是控制器类是引用的，因为它位于 org.springframework.context-3.1.1.RELEASE.jar中。因此，我不了解问题所在。

当我导航到http://localhost:8080/mvc-basic时，我正确获取了目标网页，但是当我点击该页面上的链接转到http://localhost:8080/mvc-basic/account（或http://localhost:8080/mvc-basic/account/getCreateForm）时，我得到了一个 404

有什么想法吗？

这不是我第一次尝试设置Spring MVC 3（我在stackoverflow上发布的几个问题很明显），每次我都放弃它，因为没有你可以遵循的文档这会给你留下最终的结果。文档在那里，但最终结果永远不是一个工作项目！对于任何可能建议http://viralpatel.net/blogs/2010/06/spring-3-mvc-create-hello-world-application-spring-3-mvc.html的人我已经尝试过并且喜欢该网站上的许多评论我也发现它不起作用。
