带有tile的Spring MVC：java.lang.NoClassDefFoundError：org / springframework / beans / factory / NoUniqueBeanDefinitionException

Question

我是春天新手，我正在关注一些在线教程网站，试用我的第一个网站spring-mvc，hibernate with mySQL作为后端，tile。

我已经配置了一些文件并将所有必要的jar包含在这个项目中，当我尝试从我的eclipse启动我的Apache-tomcat-7实例时，我收到以下错误。

我已经阅读了超过15个具有相同异常的线程，但由于我缺乏知识，我无法解决我的问题。我在2天内一直在努力解决这个问题。

如果我需要粘贴任何其他信息，请告诉我。

以下是我的错误消息：

Answer 1

您在项目编译期间提供了Spring类（从属jar），但在运行时没有提供。

您的Apache-tomcat-7服务器无法解析和加载Spring依赖项（jar文件），因此您需要将Spring jar添加到Tomcat类路径中。

因此，将spring依赖jar文件复制到Tomcat/webapps/yourproject/WEB-INF/lib folder或直接复制到Tomcat/lib文件夹。
