ClassNotFoundException DispatcherServlet（Tomcat 7.0.32，Spring 3.1.1，web-app 3.0，JSP，AWS，maven）

标签： spring maven web-applications tomcat7

我在创建web-app 3.0应用程序时遇到了很多问题。我设法使用google和stackoverflow以及其他论坛解决了很多问题...但现在我不仅仅是困惑。我对Web应用程序和Spring完全不熟悉。我想使用Spring 3.1库在Tomcat 7 localhost（之后是AWS的Tomcat 7）上创建我的第一个WORKING App（web-app 3.0）。在安装了大量的eclipse插件之后（AWS Toolkit for Eclipse，Maven Integration for Eclipse，Maven Integration for Eclipse WTP，APT M2E Con​​nector ......）我在Eclipse上与Spring有足够的争执。现在我不想用taglib来解决我的问题：

  

PA？ 12,2012 1:24:58 PM org.apache.catalina.startup.TaglibUriRule body   信息：TLD被跳过。 URI：http://java.sun.com/jstl/core_rt已定义）

但我提到它，因为可能与案件有某种联系。

我在使用冲突的Spring库之前遇到了一些问题 - 我已经从AWS SDK for Java库中删除了那些（版本3.0.7.RELEASE），所以现在项目启动并且正在显示index.jsp，但是我可以在控制台日志中看到：

我不明白，因为正在加载页面并且库被部署到WEB-INF / lib目录中（workspace.metadata.plugins \ org.eclipse.wst.server.core \ tmp0 \ wtpwebapps \ myexample \ WEB-INF \ lib）。我已经阅读了一个stackoverflows线程，手动将缺少的库添加到eclipse项目/ WEB-INF / lib目录中，但它没有帮助。 我究竟做错了什么？您可以在下面找到我的pom.xml，web.xml，myexample-servlet.xml，控制器源，控制器源，home.jsp ...以及我的文件夹结构。

我不是专家，但不应该使用该配置吗？我错过了什么吗？当然我已经让maven干净了（项目[右键单击] - ＆gt;运行 - ＆gt; maven清理）并重新启动eclipse ...请告诉我（对不起那篇长篇文章）。
