在实体中嵌入复杂对象

Question

我想嵌入以下内容

@Embeddable
public class BaseEntity implements Serializable {
@Id
@GeneratedValue
private UUID id;
@CreatedDate
@Column(name = "created_date", updatable = false)
private LocalDateTime createdDate;
}

into my room entity

@Entity
@Data
@NoArgsConstructor
@Table(name = "room")
public class room {

@EmbeddedId
private BaseEntity baseEntity;


@Column(length = 80, nullable = false)
private String name;
}

生成的表是这样的

room
id
createdDate
name

但是id和createdDate没有嵌入

Answer 1

将@Embeddable扩展为BaseEntity

@MappedSuperclass 
@Getter
@Setter
public class BaseEntity implements Serializable {
@Id
@GeneratedValue
private UUID id;
@CreatedDate
@Column(name = "created_date", updatable = false)
private LocalDateTime createdDate;
}
@Entity
@Data
@NoArgsConstructor
@Table(name = "room")
public class room extends BaseEntity{
@Column(length = 80, nullable = false)
private String name;
}
