Hibernate：在实体

Question

我有以下实体：

@Entity
@Table(name = "calendar")
public class Calendar {
    @Id 
    @GeneratedValue(generator = "uuid2")
    @GenericGenerator(name = "uuid2", strategy = "uuid2")
    @Column(name = "id", columnDefinition = "BINARY(16)")
    private UUID id;

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

    @JsonIgnore
    @ManyToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinColumn(name = "owner", referencedColumnName = "id")
    private OrganizerUser owner;
    ...
}

如果我将该类的对象插入表中，一切正常。但是，当我向实体添加以下内容时：

@Column(name = "owner", updatable = false, insertable = false)
private UUID ownerId;

我收到以下错误：

Cannot add or update a child row: a foreign key constraint fails (`organizer`.`calendar`, CONSTRAINT `FK3f7d9mholcykdaygm3bnwhwg7` FOREIGN KEY (`owner`) REFERENCES `user_info` (`id`))

在这种情况下是否可以引用外键？如果我省略了引用并只执行owner.getId()，是否会加载OrganizerUser对象？
