JPA-用@OrderBy注释的列表不订购项目[重复]

@Entity
@Table(name = "some_class")
@SequenceGenerator(name = "default_gen", sequenceName = "some_class_id_seq", allocationSize = 1)
data class SomeClass(

    @OneToMany(mappedBy = "someClass", cascade = [CascadeType.ALL], orphanRemoval = true)
    @OrderBy("date")    
    var items: List<SomeItem>,
) : AbstractEntity()

@Entity
@Table(name = "some_item")
@SequenceGenerator(name = "default_gen", sequenceName = "some_item_id_seq", allocationSize = 1)
data class SomeItem(
    val date: LocalDate,

    @ManyToOne
    @JsonIgnore
    val someClass: SomeClass
) : AbstractEntity()

AbstractEntity 包含一些琐碎的东西,如id、createdAt等。

编辑:这个问题有点像“JPA:cannotmakeorderbywork”。对那个问题的回答给了我正确的方向。 要使测试通过,我需要在访问存储库之前调用以下函数:

private fun clearEntityManagerCache() {
    entityManager.flush()
    entityManager.clear()
    entityManager.entityManagerFactory.cache.evictAll()
}

之后 entityManager

@Inject
private lateinit var entityManager: EntityManager
