spring - 映射 OneToMany 或 ManyToOne 未映射类时出错

Question

我有这个问题：

创建名称为 'ICustomerDao' 在 com.biblio.fr.biblio.repository 中定义的 bean 时出错 嵌套异常是 org.springframework.beans.factory.BeanCreationException：创建名为“jpaMappingContext”的 bean 时出错：调用 init 方法失败；嵌套异常是 org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany 针对未映射的类：com.biblio.fr.biblio.entite.Book.loans[com.biblio.fr.biblio.entite.Loan]

这是我的代码：

@Entity
@Table(name = "BOOK")

    private Integer id;

    private String title;
