But i have added spring-web-mvc to my class path which does contain this class file.
但是我已将 spring-web-mvc 添加到包含此类文件的类路径中。

How did you add something to your CLASSPATH?
你是如何在你的 CLASSPATH 中添加一些东西的？
If you're creating a web app, the only appropriate thing is to put .class files under WEB-INF/classes and .jar files under WEB-INF/lib. If you did anything else, I'd say that it's wrong. Modifications of the startup script should not be done; local environment variables will be ignored and unlikely to be set on the server you deploy to.
如果您正在创建 Web 应用程序，唯一合适的方法是将 .class 文件放在 WEB-INF/classes 下，将 .jar 文件放在 WEB-INF/lib 下。如果你做了任何其他事情，我会说这是错误的。不应修改启动脚本；本地环境变量将被忽略，并且不太可能在您部署到的服务器上设置。
UPDATE:
更新：
If you tell me that you've done everything right according to your IDE, I'd recommend one last check: Look at the zipped or exploded WAR file that you actually deploy to Tomcat and make sure that you can see the JAR with the .class file that the error mentions. If it's not part of the WAR, you have to figure out what went wrong with your packaging. If you think the JAR is there, open it and find the .class and check the path.
如果您告诉我您已根据 IDE 正确完成所有操作，我建议您进行最后一次检查：查看您实际部署到 Tomcat 的压缩或分解的 WAR 文件，并确保您可以看到带有 .错误提到的类文件。如果它不是 WAR 的一部分，您必须弄清楚您的包装出了什么问题。如果您认为 JAR 在那里，请打开它并找到 .class 并检查路径。
You have to believe the error message you see. Instead of saying "I'm doing everything right", it's better to say "What have I missed?"
你必须相信你看到的错误信息。与其说“我做的一切都对”，不如说“我错过了什么？”

A ClassNotFoundExceptionsuggests that you don'thave Spring on the classpath. Make sure it's in your WAR's libdirectory.
AClassNotFoundException建议您在类路径上没有Spring。确保它在您的 WARlib目录中。
Also, make sure you also have commons-logging.jarin your classpath. Spring depends on this.
另外，请确保您commons-logging.jar的类路径中也有。春天取决于此。
