Question

我在一个AuthorizationPosition EE项目中有两个实体ProductAttributes和Wildfly。两者之间的映射如下：

授权位置：

  @javax.persistence.ManyToOne(fetch =  javax.persistence.FetchType.LAZY , optional=false, cascade = {javax.persistence.CascadeType.ALL})
  @javax.persistence.JoinColumn(name = "PRODUCT_ATTRIBUTES_ID", referencedColumnName="PRODUCT_ATTRIBUTES_ID")
  protected org.example.persistence.entity.ProductAttributes productAttributes;

产品属性：

  @javax.persistence.OneToMany(
        targetEntity=org.example.persistence.entity.AuthorizationPosition.class,
        mappedBy="productAttributes",
        fetch=javax.persistence.FetchType.LAZY
                    , cascade = javax.persistence.CascadeType.ALL
                 , orphanRemoval = true         )
  protected java.util.Set<org.example.persistence.entity.AuthorizationPosition> authorizationPositionsByProductAttributes;

我在两个实体中都设置了所有关系，并在em.persist()上调用ProductAttributes（作为较大结构的一部分），这是出现奇怪错误的地方（在末尾有完整的堆栈跟踪问题）：

java.lang.IllegalStateException: org.hibernate.TransientPropertyValueException: Not-null property references a transient value - transient instance must be saved before current operation : org.example.persistence.entity.AuthorizationPosition.productAttributes -> org.example.persistence.entity.ProductAttributes

我是否缺少某些东西，或者休眠（hibernate-core-5.3.1.Final）确实试图以其他方式持续存在？尽管CascadeType.ALL出现在所有关系映射中，这应该不是问题吗？

Edit1：

我在两个实体上都设置了关系。我使用与以下类似的代码（为清晰起见，删除了某些部分）：

public void addAuthorizationPositionByProductAttributes(@NotNull AuthorizationPosition authorizationPositionByProductAttributes) {
   if(this.authorizationPositionsByProductAttributes.add(authorizationPositionByProductAttributes)){
      authorizationPositionByProductAttributes.setProductAttributes(this);
   }
}

当我在调试中检查它时，这些值已正确设置。

Answer 1

我有点惊讶。我们尝试了所有建议：

@mrtna remove Cascade.ALL from the ProductAttributes -> AuthorizationPosition
@JonathanJohx remove orphanRemoval = true , referencedColumnName="PRODUCT_ATTRIBUTES_ID") optional=false,
@TiMr remove optional and add nullable=false to the join column and change lazy to Eager
@alekz same AuthorizationPosition entity is added to two ProductAttributes?

但是似乎没有任何效果，有些导致空约束验证问题（ORA-01400），而另一些行为完全相同。

虽然测试性能我们在persistence.xml中完全禁用了验证（用于比较测试）：

<validation-mode>NONE</validation-mode>

由于意外地错误地上传了错误的文件-令我惊讶的是-该结构保持了良好的状态，没有任何错误或约束违规...

TL.DR。： 。它是验证器中的休眠错误，阻止了我们继续操作。如果validation-mode设置为NONE，则该结构得以保留。我们现在检查em.persist(..)调用之前的验证信息，并据此评估结果。

Answer 2

您是否尝试从AuthorizationPosition中删除optional=false？

有时候，Hibernate无法将事情摆在“正确”的顺序上。

Hibernate有时需要在外键中存储NULL，即使有避免它的理论方法也是如此。在这种情况下，您必须删除非空约束。（我从外键中删除了所有非空约束...）

您可以尝试从AuthorizationPosition中删除级联，这可能是订购问题的原因。但是我想它不会改变任何东西。

即使级联为ALL
