具有嵌套复合主键实体的Spring Data JPA Persisting Entity本身是一个在持续时间分离的嵌套实体

[英]Spring Data JPA Persisting Entity with a nested Composite Primary Key entity with itself a nested entity which is detached at persist time

我有三个jpa实体,我正在努力合作。 BoxProfile,BoxProfileItemAssignment和BoxItem所有代码如下所列。 BoxProfileItemAssignment使用@MapId的@EmbeddedId来映射复合键。

BoxProfile有一组BoxProfileItemAssignments,赋值是BoxItem和Quantity值。 我希望能够在持久化新的BoxProfile的同时保留BoxProfileItemAssignments。 BoxProfileItemAssignments中的每个BoxItem在创建BoxProfile时已经被保留。

我正在使用spring数据JpaRepository接口来保存我的BoxProfile实体并通过服务层BoxProfileService访问repo。

当我尝试持久化一个新的BoxProfile实体时,由于分离的实体,我得到一个PersistenceException。 我理解嵌套在我传入的BoxProfileItemAssignment实体中的BoxItem是分离的,但我不打算对所述实体进行更改或更新,我只想使用它创建BoxProfileItemAssignment条目。

经过大量研究后,我似乎无法找到一个嵌套复合键实体持久化的示例,该实体本身具有嵌套实体。

如果有人能告诉我正确的注释组合是什么来实现我的目标,我将不胜感激。

问题不是由您的映射引起的,而是由您处理“现有”实体的方式引起的。

正如您所说BOX_ITEM_ONE已经存在,但您在测试方法中使用的EntityManger不知道。

在您的情况下,您可能在testsetup期间持久化了BOX_ITEM_ONE,或者您使用find获取了它但使用了与测试方法不同的EnittyManager,因此该对象对您的EnityManger仍然是“新的”,但至少EM认识到它是JPA管理的实体,所以你得到了超然的例外。

如果您使用DB中存在的id和属性“手动”创建BOX_ITEM_ONE,则会出现错误'无法使用相同的主键(或沿着这些行的某些内容)进行INSERT,因为EM会尝试保留“新对象”,但是已经设置了PrimaryKey。

简单地说,您需要通过将其添加到EM上下文来使EM知道BoxItem。 这是合并方法,您只需调用BOX_ITME_ONE = EM.merge(BOX_ITEM_ONE),然后将其添加到新的BoxProfile中。 或者更好的是,如果在更新BoxItem的同时防止“对象已更改异常”,则使用当前的EM找到对象,BOX_ITEM_ONE = em.find(BobItem.class,BOX_ITEM_ONE.getID())。 它不会发出新的sql语句,它只会从JPA上下文中获取对象,因此它不是性能问题。

最后,您可能希望在BoxProfile中的itemAssignments上添加orphanRemoval = true到您的OneToMany anotation,因为如果您从集合中删除它们可能会删除ItemsAssignments,因为它们本身没有意义。
