Question

我试图用三个表编写一个OneToOne关系：Owner，Property和OwnerProperty OwnerProperty具有由属性和所有者的2个外键组成的复合主键

图：

所有者类：

@Setter
@Getter
@Entity
@Table(name = "Owner")
public class Owner {
    @Id
    @GeneratedValue
    private Long id;

    @OneToOne(mappedBy="ownerPropertyKey.owner", cascade = CascadeType.ALL)
    @JsonIgnoreProperties(value = "ownerPropertyKey.owner", allowSetters = true)
    private OwnerProperty ownerProperty;

属性类：

@Setter
@Getter
@Entity
@Table(name = "Property")
public class Property {
    @Id
    @GeneratedValue
    private Long id;

    @OneToOne(mappedBy="ownerPropertyKey.property", cascade = CascadeType.ALL)
    @JsonIgnoreProperties(value = "ownerPropertyKey.property", allowSetters = true)
    private OwnerProperty ownerProperty;

OwnerProperty类：

@Setter
@Getter
@Entity
@Table(name = "OwnerProperty")
public class OwnerProperty {

    @EmbeddedId
    private OwnerPropertyKey ownerPropertyKey;

    public OwnerProperty(OwnerPropertyKey ownerPropertyKey){
        this.ownerPropertyKey = ownerPropertyKey;
    }

    public OwnerProperty(){

    }
}

OwnerPropertyKey类：

@Data
@Setter
@Getter
@Embeddable
public class OwnerPropertyKey implements Serializable {
    @OneToOne
    @JoinColumn(name = "owner_id", referencedColumnName = "id")
    @JsonIgnoreProperties(value = "ownerProperty", allowSetters=true)
    private Owner owner;

    @OneToOne
    @JoinColumn(name = "property_id", referencedColumnName = "id")
    @JsonIgnoreProperties(value = "ownerProperty", allowSetters=true)
    private Property property;

    public OwnerPropertyKey(Owner owner, Property property){
        this.owner = owner;
        this.property = property;
    }

    public OwnerPropertyKey(){

    }
}

以及尝试保存ownerProperty时遇到的错误：

我找不到问题所在，有人可以帮助我吗？谢谢。
