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

Question

环境：

• Jboss 7.2
• Java 11
• 休眠

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

Oferta 1->N OfertaInscripcio

错误ORA-00904："；OFERTA_OFT_ID"：标识符无效

应该只有OFT_ID

知道吗？

Answer 1

您必须将@Joincolumn放在指定列名的字段oferta上。如果没有，则名称将由变量名检索。

@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;
}
