Error mapping OneToMany or ManyToOne unmapped class - spring

Question

I have this problem :
Error creating bean with name 'ICustomerDao' defined in com.biblio.fr.biblio.repository.ICustomerDao defined in #EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Cannot resolve reference to bean 'jpaMappingContext' while setting bean property 'mappingContext'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is org.hibernate.AnnotationException: Use of #OneToMany or #ManyToMany targeting an unmapped class: com.biblio.fr.biblio.entite.Book.loans[com.biblio.fr.biblio.entite.Loan]
this is my code :
