java - 类 org.springframework.web.context.ContextLoaderListener 未找到

Question

当我使用 eclipse 和 maven 创建一个新的 Spring MVC 项目时，当我以 maven build 运行时会引发以下错误（目标是 tomcat:run）。我在清理并安装后进行了构建。

严重：配置类 org.springframework.web.context.ContextLoaderListener 的应用程序侦听器时出错

java.lang.ClassNotFoundException：org.springframework.web.context.ContextLoaderListener

此问题的其他解决方案是从项目属性中在部署程序集中添加 Maven 依赖项。
但是，当我右键单击属性时，部署程序集选项不存在。
我也尝试手动添加 spring.jar。
org.springframework.web.context.ContextLoaderListener 类存在于 maven 依赖项中，但仍然抛出错误。

pom.xml

我的 pom.xml 如下：

这是因为您在 maven pom.xml 上标记了 Spring 依赖项，<scope>provided</scope>并且在运行程序时没有在类路径中包含实际的 jar。有两种可能的解决方案：

将依赖范围更改为 compile
运行应用程序时，将具有匹配版本的 spring jar 包含到您的类路径中
