问题

当批处理被启用时，hibernate以错误的顺序插入实体 hibernate.order_inserts=true . 这将导致外键冲突。我们有一个事务，它创建了一种包含许多不同实体的模型。所有内容都通过级联保存，包括提供外键冲突的以下实体：

public class PlanItemDefinition {
    @Id
    @Column(name = "id")
    @GeneratedValue(generator = "uuid2")
    @GenericGenerator(name = "uuid2", strategy = "uuid2")
    private UUID id;
    ...
    @OneToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL, orphanRemoval = true)
    @JoinColumn(name = "default_control_id", foreignKey = @ForeignKey(name = "fk_plan_item_definition_default_control_id"))
    private PlanItemControl defaultControl;
    ...
}
public class PlanItemControl {
    @Id
    @Column(name = "id")
    @GeneratedValue(generator = "uuid2")
    @GenericGenerator(name = "uuid2", strategy = "uuid2")
    private UUID id;
    ...
    @OneToOne(mappedBy = "defaultControl")
    private PlanItemDefinition planItemDefinition;
    ...
}

当事务提交时，hibernate引发以下异常：

Caused by: java.sql.BatchUpdateException: Batch entry 1 insert into model.plan_item_definition

当我移除 hibernate.order_inserts=true 一切正常。这似乎是同一个问题https://hibernate.atlassian.net/browse/hhh-9864?attachmentsortby=datetime 但是既然我们使用的是hibernate 5.2.17.final版本，这个问题应该得到解决吗？

问题

有人能告诉我这是一个冬眠虫还是我们做错了什么吗？hibernate不考虑insert语句在级联时的顺序吗 hibernate.order_inserts=true ?
