java - 应用程序类(应用程序监听器)org.springframework.web.context.ContextLoaderListner 的配置错误

Question

我在使用 spring 时遇到问题，我是一个使用 Hibernate、JPA 和 Maven 框架的新手，我正在关注pluralsight 的教程，但是在服务器中启动应用程序时，我收到此错误消息

我尝试了几乎所有可能的解决方案，例如将 Maven 依赖项添加到构建路径或清理 tomcat 工作目录。

谢谢

要在 eclipse 中解决此错误:右键单击您的项目 --> 属性 -> 部署程序集 -> 添加 -> Java 构建路径条目 -> Maven 依赖项(全部选择) -> 完成
