Question

我尝试将Java应用程序重构为Kotlin，它是用Spring Boot编写的。我将所有文件都转移到了新项目中，但是当我运行该应用程序时，总是会收到此错误：不是托管类型：com.contactlist.contactlistapp.model.User

类

我尝试（我认为）在这里找到的所有答案，但没有一个可以解决问题。

错误消息

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'restApiController': Unsatisfied dependency expressed through field 'userService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userService': Unsatisfied dependency expressed through field 'userRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class com.contactlist.contactlistapp.model.User
