Spring UnsatifiedPendencyException:创建名为的bean时出错

我正在尝试在Spring上创建db服务器，并研究了许多类似的问题，但没有人能帮到我。我无法解决此错误：

org.springframework.beans.factory.unsatifiedpendencyException:创建名为“groupController”的bean时出错：通过字段“gs”表示未满足的依赖关系；嵌套异常为org.springframework.beans.factory.unsatifiedpendencyException:创建名为“groupServiceImpl”的bean时出错：未满足的依赖项通过字段“gr”表示；嵌套异常为org.springframework.beans.factory.beancreatitionException:创建名为“groupRepository”的bean时出错：在设置bean属性“entityManager”时，无法创建[org.springframework.orm.jpa.SharedEntityManagerCreator]类型的内部bean（内部bean）#1a3c15e0；嵌套异常为org.springframework.beans.factory.BeanCreationException:创建名为“（内部bean）#1a3c15e0”的bean时出错：设置构造函数参数时无法解析对bean“entityManagerFactory”的引用；嵌套异常为org.springframework.beans.factory.NoSuchBean定义异常：没有名为“entityManagerFactory”的bean可用

以下是我的课程：
