孙 object 没有更新

Question

我有一个 parent、一个 child 和一个 grandchild object。问题是，当我删除应用程序中的 grandchildren 并保存时 parent object, grandchildren 更改不会更新。

在ParentClass

  @OneToMany(fetch = FetchType.EAGER, mappedBy = "parent")
  @ForeignKey(name = "FK_1")
  @Cascade({CascadeType.ALL})
  private Set<Child> children;

在ChildClass

  @ManyToOne(fetch = FetchType.EAGER)
  @JoinColumn(name = "parent")
  @XmlTransient
  private parent parent;

  @OneToMany(fetch = FetchType.EAGER, mappedBy = "child")
  @ForeignKey(name = "FK_2")
  @Cascade({CascadeType.ALL})
  private Set<GrandChild> grandchildren;

盛大ChildClass

  @ManyToOne(fetch = FetchType.EAGER)
  @JoinColumn(name = "child", nullable = false)
  @XmlTransient
  private Child child;

我使用 hibernate 4.2.2.Final.

有什么想法吗？

Answer 1

尝试将 orphanRemoval 添加到您的 collections。

@OneToMany(fetch = FetchType.EAGER, mappedBy = "parent", orphanRemoval=true)
@OneToMany(fetch = FetchType.EAGER, mappedBy = "child", orphanRemoval=true)
