但我已将 spring-web-mvc 添加到包含此类文件的类路径中.

推荐答案

但我已将 spring-web-mvc 添加到我的包含这个的类路径类文件.

您是如何在 CLASSPATH 中添加内容的?

如果您正在创建一个 Web 应用程序,唯一合适的做法是将 .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.

更新:

如果您告诉我您根据您的 IDE 所做的一切都是正确的,我建议您进行最后一项检查: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 JAR使用错误提到的 .class 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 存在,请打开它并找到 .class 并检查路径.

你必须相信你看到的错误信息.与其说"我做的一切都正确",不如说"我错过了什么?"
