上下文初始化过程中遇到的异常-取消刷新尝试org.springframework.beans.factory.BeanDefinitionStoreException

Question

我只是学习如何在不使用xml文件的情况下进行组件扫描。但是，当我使用xml代码时，我的应用程序可以工作，但是没有xml，我的应用程序就会抛出上面的错误，这可能是陈词滥调，但我对这些程序并不熟悉，所以希望您能帮我解决这个问题。如果我在xml中使用组件，或者不使用xml，那么它就不能工作。这是我的代码这是我的完全错误

实际上，我找到了答案，因为我的eclipse使用jdk 17运行，而我安装了jdk 16.0.2，您只需单击项目-> build >配置构建路径->java编译器->编译器遵从级别到更低的jdk级别，这要感谢每个人的帮助。
