hibernate ManyToOne 与 OfertaInscripcio 映射 Oferta 时的标识符无效

Question

环境：

• Jboss 7.2
• Java 11
• Hibernate

用java属性映射数据库字段时一定是某种错误，它将前缀OFERTA_添加到OFT_ID（主键），但我看不出这是在哪里发生的。

Oferta 1->N OfertaInscripcio

错误 ORA-00904：“OFERTA_OFT_ID”：无效标识符

它应该只是 OFT_ID

有什么想法吗？

Answer 1

您必须将 @Joincolumn 放在指定列名称的 oferta 字段上。如果没有，则通过变量名称检索名称。

@Entity
@Table(name = "AF_OFE_OFERTA_INSCRIPCIO")
public class OfertaInscripcio implements Serializable {

    @Id
    @Column(name = "ID")
    @SequenceGenerator(name = "AF_OFERTAI_GENERATOR", sequenceName = "AF_OFERTAI_SEQ", allocationSize = 1)
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "AF_OFERTAI_GENERATOR")
    private Long id;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "OFERTAID", referencedColumnName = "OFT_ID")
    private Oferta oferta;

    @Column(name = "OFERTAID", insertable = false, updatable = false)
    private Long idOferta;
}
