即使级联设置为ALL，Hibernate仍无法持久化。

Question

即使级联设置为ALL，Hibernate仍无法持久化。

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

AuthorizationPosition：

  @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），这是奇怪错误出现的地方（完整的堆栈跟踪在问题的末尾）：

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

我是否漏掉了什么或者 Hibernate (hibernate-core-5.3.1.Final) 真的在尝试以另一种方式进行持久化吗？虽然所有关系映射上都存在 CascadeType.ALL，但这不应该是一个问题，对吧？

Edit1:

我在这两个实体之间建立了关系。我使用类似以下的代码（某些部分已被删除以提高清晰度）：

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

当我在调试时检查它，数值被正确设置。

你可以展示一下在持久化之前如何设置实体吗？ - Maciej Kowalski

嗨，也许你可以从ProductAttributes -> AuthorizationPosition的链接中删除Cascade.ALL吗？我不确定这是否会解决问题，但我认为这可能会导致实体“ProductAttributes”被持久化两次。 - mrtna

删除这些配置 orphanRemoval = true，referencedColumnName="PRODUCT_ATTRIBUTES_ID") optional=false，就可以正常工作了。 - Jonathan JOhx

你尝试过从AuthorizationPosition中删除optional=false吗？

有时，Hibernate无法将事物放入“正确”的顺序中。

即使存在理论上的避免方法，Hibernate有时仍需要在外键中存储NULL。在这些情况下，您必须删除非空约束。（我已经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，它可能是导致排序问题的原因。但我想这不会改变任何内容。

我有点惊讶。我们尝试了所有的建议：

@mrtna 从ProductAttributes中删除Cascade.ALL -> AuthorizationPosition
@JonathanJohx 删除orphanRemoval = true，referencedColumnName="PRODUCT_ATTRIBUTES_ID") optional=false,
@TiMr 删除optional并将nullable=false添加到连接列，并将lazy更改为Eager
@alekz 两个ProductAttributes都添加了相同的AuthorizationPosition实体？

但是似乎没有任何作用，有些导致了空约束验证问题（ORA-01400），其他行为完全相同。

在测试性能时，我们完全禁用了验证（进行比较测试）在persistence.xml中：

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

And with an accidental missclick on the wrong file to upload - to my surprise - the structure persisted fine without having any errors or constraint violations...

TL.DR.: 这是一个Hibernate验证器的bug，导致我们无法持久化。如果设置为，则结构将被持久化。现在，在调用之前，我们检查验证信息并相应地评估结果。
