解决hibernate错误：实体映射中的重复列？

Question

我有表ctl与表有两个关系：psr和psg。 此表与PK具有相同的名称：COD_FILEFE_S

public class Psr{
  @Id
  @Column(name = "COD_FILEFE_S")
  private BigDecimal codFilefeS;
}

public class Psg{
  @Id
  @Column(name = "COD_FILEFE_S")
  private BigDecimal codFilefeS;
}

可以用hibernate映射这个吗？ 使用以下模型，我有org.hibernate.MappingException：实体映射中的重复列：

public class Ctl{

/** The cod filefe s. */
@ManyToOne(targetEntity = Psg.class)
@JoinColumn(name = "COD_FILEFE_S", referencedColumnName = "COD_FILEFE_S", nullable = false)
private BigDecimal codFilefeS;

/** The cod filefe s. */
@ManyToOne(targetEntity = Psr.class)
@JoinColumn(name = "COD_FILEFE_S", referencedColumnName = "COD_FILEFE_S", nullable = false)
private BigDecimal codFilefeSPert;

}

Answer 1

正如您提到的两列相同的名称，您收到此错误.. 更改第二个列的名称..

public class ctl{

/** The cod filefe s. */
@ManyToOne(targetEntity = Psg.class)
@JoinColumn(name = "COD_FILEFE_S", referencedColumnName = "COD_FILEFE_S", nullable = false)
private BigDecimal codFilefeS;

/** The cod filefe s. */
@ManyToOne(targetEntity = Psr.class)
@JoinColumn(name = "COD_FILEFE_S_PERT", referencedColumnName = "COD_FILEFE_S", nullable = false)
private BigDecimal codFilefeSPert;

}
