Java org.hibernate.AnnotationException:从y引用x的外键的列号错误。应该是n

在hibernate初始化期间发生以下异常：

org.hibernate.AnnotationException: A Foreign key refering com.maar.projectbuilder.domain.Language from com.maar.projectbuilder.domain.ItemInfo has the wrong number of column. should be 0

我有上面截图中的表格。 实体类编写如下

public class ItemInfo implements Serializable {

   @Column(name = "name")
   private String name;

   @Id
   @OneToOne(cascade = CascadeType.ALL)
   @JoinColumn(name = "item_id", nullable = false)
   private Item itemId;

   @ManyToOne(targetEntity = Language.class,cascade = CascadeType.ALL)
   @JoinColumn(name = "language_item_id", nullable = false)
   private Language languageItemId;

   @Column(name = "type", nullable = false)
   private Integer type;
   //getters,setters,constructors
}

另一个

public class Language implements Serializable {
   @Column(name = "isDefault")
   private Integer isDefault;

   @Column(name = "abbr")
   private String abbr;

   @Column(name = "name")
   private String name;

   @Id
   @OneToOne(cascade = {CascadeType.ALL})
   @JoinColumn(name = "item_id")
   private Item itemId;
}

我的项目实体

public class Item implements Serializable {
   @Column(name = "c4i")
   private String c4i;

   @Column(name = "status")
   private Integer status=1;

   @Id
   @GeneratedValue(strategy = GenerationType.AUTO)
   @Column(name = "id")
   private Integer id;
}

我怎样才能解决这个问题。我错过了什么？

提前谢谢你

在E-R图中，item\u info使用join主键：item\u id、language\u item\u id和type，但在映射中，您只映射了item\u id

我将referencedColumnNameparam添加到JoinColumn注释中，现在一切正常

最后一个实体看起来像这样

public class ItemInfo implements Serializable {

    @Column(name = "name")
    private String name;

    @Id
    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "item_id", nullable = false)
    private Item itemId;

    @ManyToOne
    @JoinColumn(name = "language_item_id",**referencedColumnName = "item_id"**)
    private Language languageItemId;

    @Column(name = "type", nullable = false)
    private Integer type;
}

谢谢大家。祝您有愉快的一天。

语言中@OneToMany与itemInfo的关系缺失。请添加它们并重试。我已解决问题，谢谢您的帮助
