@凌驾
public Collection将Main移到根包中。这样，您的结构看起来像下面这样

src/main/java
    -> EaskantApplication (which I guess is the Main class)
        -> All other packages

通常，当主类不在根目录下时，它往往无法找到所需的资源。
将easkartaplication.java移到新包中
e、 g.com.easkart.app
感谢Alain的回复。现在我得到以下警告**警告**：由于默认包的@ComponentScan，您的应用程序上下文不太可能启动。当我从用户类中删除安全包和属于安全包的类的引用时，它可以正常工作。欢迎您！我很高兴您能够修复您的问题问题！谢谢kossak，现在可以用了。我真的很感谢你的帮助。
src/main/java
