[yujmh]

hibernate继承映射@Inheritance(strategy=InheritanceType.JOINED)，知道父类的id时，怎么去为子类插入一条记录？a][/code]类id插入子类记录

@Entity
@Table(name = "base_org", schema = "", catalog = "oeasy")
@Inheritance(strategy = InheritanceType.JOINED)
public class BaseOrgEntity{
 @Id
    @Column(name = "id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    public long getId() {
        return id;
    }
}

@Entity
@Table(name = "enterprise_org", schema = "", catalog = "oeasy")
@PrimaryKeyJoinColumn(name = "id", referencedColumnName = "id")
public class EnterpriseOrgEntity extends BaseOrgEntity {}
