spring - 无法解析未找到 WebApplicationContext : no ContextLoaderListener registered

我正在尝试仅使用注释创建 Spring Web 应用程序(无配置 xml 文件)。我使用 tomcat 作为应用程序服务器，使用 Maven 来构建项目。谷歌搜索了很多，修改了很多，但仍然遇到这个错误。请在下面找到这些文件。希望可以有人帮帮我。提前致谢。 :)

下面是 pom.xml

您的web.xml 是错误的。您想要使用 ServletContainerInitializer(Spring 提供的)，它是 servlet 规范 3.0 的一部分。但是，您的 web.xml 使容器在 2.3 模式下运行。修复您的 web.xml。

接下来，虽然不直接相关，但您很快就会遇到问题，因为您正在混合不同版本的 Spring 框架。切勿混合来自不同版本框架的 jar(不仅是 spring，而且是所有框架)。提示使用单个属性来定义您要使用的版本。
