Question

我正在使用EclipseLink 2.6.3（也尝试使用2.6.2），我面临着一个非常奇怪的情况：数据库（Oracle 12c）抱怨以下消息：

ORA-02291：违反了完整性约束（LOG_SUB_LO_ID_FK） - 未找到父密钥

但是，在查看日志时，他们似乎建议引用的父键应该在那里，它们显示以下内容：

表格如下：

LOGS（PK是ID）
LOG_SUB（PK是ID，LO_ID是FK到LOGS）
LOG_PARAM（PK是ID，LO_ID是FK到LOGS）

映射到JPA对象相对简单：

Log类（与LOGS表匹配）与LogSub和LogParam的2 @OneToMany个关系，标记为级联ALL
LogSub（对于LOG_SUB表）和LogParam（对于LOG_PARAM表）都与@ManyToOne的关系Log被标记为不可为空且可选= false

我创建了我的Log对象并添加了1个LogSub和1个LogParam（每个关系一个），然后保留我的Log对象。

当我的交易提交时，我随机收到上述错误。

有关信息：我正在使用EclipseLink与Spring-Jpa和Spring-Data以及启用JDBC批处理写入。

为简单起见，我删除了一些数据

如有需要，请随时提出更多详情。

Eclipselink外键约束违规但SQL插入顺序似乎没问题
