java - 映射通过引用 com.bookstore.entity.Book.detailOrders 中的未知目标实体属性 : com. bookstore.entity.DetailOrder.books

Question

我在名为 DetailOrder 和 Book 的两个类中遇到映射问题。

问题如下所示。

Initial SessionFactory creation failed.
org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: com.bookstore.entity.DetailOrder.books in com.bookstore.entity.Book.detailOrders

如何修复它？

类如下所示。

DetailOrder 类

@ManyToOne(fetch = FetchType.EAGER,cascade=CascadeType.ALL)
@JoinColumn(name = "BOOK_ID")
private Book book;

读书课

@OneToMany(fetch = FetchType.EAGER,mappedBy = "book", cascade=CascadeType.ALL)
private Set<DetailOrder> detailOrders = new HashSet<DetailOrder>();
