Not a managed type: class com.example.demo.dto.Person

Столкнулся с такой проблемой.

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'personRepository' defined in com.example.demo.repository.PersonRepository defined in @EnableJpaRepositories declared on DemoApplication: Not a managed type: class com.example.demo.dto.Person

Я думаю, что это из за того, что он не видит сущности. Хотя они объявлены
