org.hibernate.MappingException：OneToOne Mapping实体映射中的重复列

Question

我正在两个班级OneToOne和SkuImpl之间建立SkuAvailability关系。下面是那个

的代码

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时，它没有部署，得到例外

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

如何解决这种异常？

Answer 1

尝试像这样写@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;
