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

当我尝试启动我的应用程序时，console会显示下一个stacktrace：

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

我也读过同样的问题，但是没有spring web jar，但是在pom.xml中我包含了spring依赖项，问题仍然存在：

         <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>

看起来您的应用程序存在一些配置问题。你可以参考这个链接

您的spring版本是什么

在项目上运行

mvn clean install

然后

mvn tomcat:run

显示结果日志

您需要将war文件与您的项目打包，并尝试将其部署到独立的Tomcat上

这本身不是一个答案，但需要键入超出我在注释中所能容纳范围的内容。这只告诉您如何启用EclipseTomcat实例的日志记录。启用EclipseTomcat实例的日志记录比我记忆中更混乱。您仍然可以编辑运行时配置。在VM参数下的“参数”选项卡上，添加2个属性：

-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager 
-Djava.util.logging.config.file=/path_to_your/logging.properties

这将允许您根据logging.properties文件进行日志记录（该文件可以放在任何地方-我很少更改我的Eclipse服务器，所以我只在那里的“conf”目录中放置一个副本）

如果您需要一个方便的文件，下面是logging.properties文件的副本：

spring版本是3.0.6.release可能，maven找不到JAR，但它们在存储库中，类和方法通常被调用。但问题项目无法启动让我更担心也许这些问题有关联？更重要的是，您的项目必须在没有任何IDE的情况下工作。@JohnSmith您需要将war文件与您的项目打包，并尝试将其部署到独立的Tomcat上。@JohnSmith在我看来，您的类路径中的库太乱了。某些库可能与其他库冲突。例如，如果您有两个版本的spring-web.jarI使用maven，并且链接中的spring版本太旧，听起来您想用Eclipse从中运行？不是100%肯定。如果是，请打开运行配置并查看您试图部署到的服务器的“参数”选项卡。这将告诉您部署的位置。它通常位于…/.metadata/某处。。。。去那里，查看catalina.out和localhost.todaydate.log的“logs”目录，看看报告了哪些错误。是的，我正在使用eclipse。我没有发现日志。我在许多文件夹中查找了它们，但没有结果：（必须添加一个“答案”来告诉您如何启用它-很抱歉，我之前忘记了详细信息。试试看，看看是否有任何错误。约翰，我昨天遇到了一个非常类似的问题，并在上发布了一些提示

java.lang.ClassCastException: org.springframework.web.filter.DelegatingFilterProxy cannot be cast to javax.servlet.Filter
