스프링 부트 : 이름이 'jpaContext'인 빈을 생성하는 중 오류가 발생했습니다 : NoSuchBeanDefinitionException

Question

스프링 부트, 하이버 네이트 및 MySQL을 사용하여 기본 CRUD API를 수행하려고합니다. 나는 this tutorial을 팔로우하고 있습니다. 나는 이것에 달려있다 :

UnsatisfiedDependencyException: Error creating bean with name 'jpaContext': Unsatisfied dependency expressed through constructor parameter 0: No qualifying bean of type [java.util.Set] found for dependency [java.util.Set<javax.persistence.EntityManager>].

나는이 SO post을보고 있지만 아무 대답이 없기 때문에 훨씬 도움이되지 않았다. 내 이해는 JPA 주석으로 객체를 지속시키기 위해 Hibernate API를 사용하고 있다는 것이다. pom.xml에 JPA 종속성을 추가해야합니까? 나는 정말로 혼란 스럽다.

모든 도움을 주시면 매우 감사하겠습니다. CRUD API를 간단하게 설정하고 다음 튜토리얼을 꽤 포괄적 인 것으로 생각했습니다.
