我正在将我的项目迁移到Hibernate 5.0。我们使用生成的DDL有多种原因，因此DDL应该与以前完全相同。除了@ForeignKey @JoinColumn关系@OneToMany中的@Entity
@Table(name = "CHILD", indexes = { @Index(columnList = "NAME", name = "IDX_CHILD_NAME") }, uniqueConstraints = { @UniqueConstraint(columnNames = "NAME", name = "UK_CHILD_NAME") })
@SequenceGenerator(allocationSize = 1, name = "CHILD_ID_GENERATOR", sequenceName = "CHILD_ID_SEQ")
public class Child {
@Id
@GeneratedValue(generator = "CHILD_ID_GENERATOR", strategy = SEQUENCE)
@Column(name = "ID")
private Long id;
@Column(name = "NAME")
private String name;
@OneToMany()
@JoinColumn(name = "CHILD_ID", foreignKey = @ForeignKey(name = "FK_CHILD_PET"))
private List<Pet> pets;
}
名称之外，我的大部分内容都有效。
我有一个子实体：
@Entity
@Table(name = "PET", indexes = { @Index(columnList = "NAME", name = "IDX_PET_NAME") }, uniqueConstraints = { @UniqueConstraint(columnNames = "NAME", name = "UK_PET_NAME") })
@SequenceGenerator(allocationSize = 1, name = "PET_ID_GENERATOR", sequenceName = "PET_ID_SEQ")
public class Pet {
@Id
@GeneratedValue(generator = "PET_ID_GENERATOR", strategy = SEQUENCE)
@Column(name = "ID")
private Long id;
@Column(name = "NAME")
private String name;
}
和宠物实体：
alter table PET add constraint FKaxwc707slbsrp6vgxyyydrvcy foreign key (CHILD_ID) references CHILD
但是当我尝试生成DDL时，我得到以下声明：
@OneToMany()
@org.hibernate.annotations.ForeignKey(name = "FK_CHILD_PET")
@JoinColumn(name = "CHILD_ID")
private List<Pet> pets;
当我更改注释以包含Hibernate的弃用的ForeignKey时，如此
alter table PET add constraint FK_CHILD_PET foreign key (CHILD_ID) references CHILD
我确实得到了所需的输出
[['C'], ['B'], ['A'], ['C', 'B'], ['B', 'A'], ['A', 'C']]
但我想删除那个已弃用的Hibernate ForeignKey注释。
有什么建议吗？
