Answer 1

当我通过@import导入未部署在服务器上的类时,我遇到了这个错误.不幸的是,堆栈并没有告诉你缺少哪个类,但你可以逐个删除它们并重新启动你的应用程序.

现在,如果项目实际编译,为什么不在服务器上部署该类？

编辑:当我通过Maven依赖使用类路径上的类时,我发现我遇到了问题.我还在Eclipse中检查了这个依赖项(项目).在这种情况下,Eclipse似乎将部署签出的项目而不是存储库中的构建.它不会考虑这个项目的外部依赖性.

解决方案:关闭Eclipse中的所有外部依赖项目,以确保实际部署Maven资源库中的版本.

你可能会失踪

<context:component-scan base-package="org.example">

在您的 applicationContext.xml 文件中或

@ComponentScan("com.example") 

如果您正在进行基于代码的配置，请使用注释。
