Question

我正在使用Eclipselink 2.5 我正在讨论3个实体关系。 Review_Group，Review和Artifact。场景是我创建一个Review_Group然后我创建一个Review然后一个Artifact，现在我去更新我的Review_Group并添加一些用户作为组的成员它创建用户并添加成员但它也更新了审查表并删除了Review_Group并更新工件表并删除审阅ID

工件可以是任何人Review_Group或Review的一部分从 Review_Group 到Review和Artifact

的关系

@OneToMany(mappedBy = "reviewGroup", cascade = CascadeType.ALL,  fetch = FetchType.LAZY)
Set<Review> Reviews;

@OneToMany(mappedBy = "ReviewGroup", cascade = CascadeType.ALL, fetch = FetchType.LAZY, orphanRemoval = true)
Set<Artifact> Artifacts;

从审核到Review_Group和Artifact

的关系

@ManyToOne(fetch = FetchType.LAZY, optional = true, cascade = { CascadeType.REFRESH, CascadeType.MERGE })
@JoinColumn(name = "REVIEW_GROUP_ID", referencedColumnName = "UUID")
@XmlIDREF
Review_Group reviewGroup;

@OneToMany(mappedBy = "Review", fetch = FetchType.LAZY, orphanRemoval = true, cascade = ALL)
Set<Artifact> artifacts;

从工件到Review and ReviewGroup

的反向关系

@ManyToOne(fetch = FetchType.LAZY, optional = true, cascade = { CascadeType.REFRESH, CascadeType.MERGE })
@JoinColumn(name = "REVIEW_ID", referencedColumnName = "UUID")
@XmlIDREF
Review Review;

@ManyToOne(fetch = FetchType.LAZY, optional = true, cascade = { CascadeType.REFRESH, CascadeType.MERGE })
@JoinColumn(name = "REVIEW_GROUP_ID", referencedColumnName = "UUID")
@XmlIDREF

Review_Group ReviewGroup;

这里是审核和review_group，关系的所有者是review_group所以我不认为合并和刷新反面有任何影响。但即使我删除它们也会产生相同的结果。同样适用于审查和工件
