java - org.hibernate.MappingException : Repeated column in mapping for entity for OneToOne Mapping

Question

我正在两个类 SkuImpl 和 SkuAvailability 之间构建 OneToOne 关系。下面是代码

SkuImpl.java

@Entity 
public class SkuImpl implements  Sku {
    @OneToOne(targetEntity=SkuAvailabilityImpl.class) 
    protected SkuAvailability totalSku;
    //setter and getters
}

SkuAvailabilityImpl.java

@Entity 
public class SkuAvailabilityImpl implements SkuAvailability{
    @OneToOne(optional=true,targetEntity=SkuImpl.class,cascade=CascadeType.ALL) 
    @JoinColumn(name="SKU_ID")
    protected Sku sku;
    //setter and getters
}

当我尝试将应用程序部署到 glassfish 中时，它没有部署，出现异常

Caused by: org.hibernate.MappingException: Repeated column in mapping for entity:
SkuAvailabilityImpl column: SKU_ID
(should be mapped with insert="false" update="false")

如何解决这个异常？

Answer 1

尝试像这样编写@JoinColumn:

@OneToOne(optional=true,targetEntity=SkuImpl.class,cascade=CascadeType.ALL) 
@JoinColumn(name="SKU_ID",referencedColumnName="someNameOfColumnId")
protected Sku sku;

referencedColumnName 是 SkuImpl 类中的列 ID。

下面的代码是不必要的:

  @OneToOne(targetEntity=SkuAvailabilityImpl.class) 
  protected SkuAvailability totalSku;
