java - hibernate :mappedBy在oneToMany关系中引用未知的目标实体属性

我的代码具有以下结构：

用户具有TvShow的收藏夹列表，TvShow具有季节列表，一个季节具有情节列表。

用户

@Entity
@Table(name = "users")
public class User {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "user_id", updatable = false, nullable = false)
private int id;

@OneToMany(mappedBy = "tvshows", fetch = FetchType.EAGER)
private List<TvShow> favourites;
/// everything else removed for clarity
}

电视节目

@Entity
@Table(name = "tvshows")
public class TvShow {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "tvShow_id", updatable = false, nullable = false)
private int id;

@OneToMany(mappedBy = "tvshows", fetch = FetchType.EAGER)
private List<Season> seasons;
/// everything else removed for clarity
}

季节

@Entity
@Table(name = "seasons")
public class Season{

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "season_id", updatable = false, nullable = false)
private int id;

@OneToMany(mappedBy = "seasons", fetch = FetchType.EAGER)
private List<Episode> episodes;
/// everything else removed for clarity
}

该应用程序不会以以下错误消息开头：

mappedBy reference an unknown target entity property: com.gcimpoies.project.model.Season.seasons in com.gcimpoies.project.model.TvShow.seasons

也，

Invocation of init method failed; nested exception is org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: com.gcimpoies.project.model.Season.seasons in com.gcimpoies.project.model.TvShow.seasons

我很确定我只是缺少正确的属性名称（mappedBy的参数），但是我不知道我在做什么错。

提前致谢！

最佳答案

您必须放在mappedBy中的名称是您所引用的类的ID。

代替：

@OneToMany(mappedBy = "tvshows", fetch = FetchType.EAGER)

尝试：

@OneToMany(mappedBy = "id", fetch = FetchType.EAGER)

您还必须为其余映射执行此操作。
