【中文标题】即使级联为 ALL，Hibernate 也无法持续存在【英文标题】：Hibernate fails to persist even when cascade is ALL 【发布时间】：2019-01-09 11:41:32 【问题描述】：

我在 Wildfly EE 项目中有两个实体 AuthorizationPosition 和 ProductAttributes。两者的映射如下：

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;

我在两个实体中设置了所有关系并在ProductAttributes 上调用em.persist()（作为更大结构的一部分）这是出现奇怪错误的地方（问题末尾的完整堆栈跟踪）： 

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

是我遗漏了什么还是 Hibernate (hibernate-core-5.3.1.Final) 真的试图以另一种方式坚持？尽管CascadeType.ALL 存在于所有关系映射中，这不应该是个问题吗？

编辑1：

我在两个实体上都设置了关系。我使用与以下类似的代码（为清楚起见，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，值设置正确。

【问题讨论】：

你能展示你在持久化之前是如何设置实体的吗？ 嗨，也许您可​​以从 ProductAttributes -> AuthorizationPosition 链接中删除 Cascade.ALL ？我不确定这是否能解决问题，但我认为这可能会导致实体“ProductAttributes”被持久化两次 我试过了..映射的原始状态是没有那个：/ 我错过了什么？ link 因为这行得通 @xerx593 这是级联应该做的。问题是为什么级联不起作用... 【参考方案1】：

我有点惊讶。我们尝试了所有建议：

@mrtna remove Cascade.ALL from the ProductAttributes -&gt; 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?

但似乎没有任何效果，一些导致空约束验证问题 (ORA-01400) 其他人的行为完全相同。

在测试性能时，我们在persistence.xml 中完全禁用了验证（用于比较测试）：

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

并且由于意外点击错误的文件上传 - 令我惊讶的是 - 结构保持良好，没有任何错误或违反约束......

TL.DR.：这是验证器中的一个休眠错误，它阻止了我们坚持。如果validation-mode 设置为NONE，则结构将保持不变。我们现在检查em.persist(..) 调用之前的验证信息并相应地评估结果。

【讨论】：

【参考方案2】：

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

有时，Hibernate 无法将事物按“正确”的顺序排列。

Hibernate 有时需要将 NULL 存储在外键中，尽管有一种理论上的方法可以避免它。在这些情况下，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，这可能是导致排序问题的原因。但我想这不会改变任何事情。

【讨论】：

以上是关于即使级联为 ALL，Hibernate 也无法持续存在的主要内容，如果未能解决你的问题，请参考以下文章
