使用更新Cascade进行hibernate软删除

如果我有3个相互连接的类。

房间等级

@Entity @Table(name="table_room") Class Room{ @Id @GeneratedValue @Column(name="id_room") private Integer id; @Column(name="name") private String name; @OneToMany(mappedBy="room") private List people; @Column(name="deleted") private int deleted; } 

人类

  @Entity @Table(name="table_person") Class Person{ @Id @GeneratedValue @Column(name="id_person") private Integer id; @Column(name="name") private String name; @ManyToOne @JoinColumn(name="id_room") private Room room; @OneToMany(mappedBy="person") private List phones; @Column(name="deleted") private int deleted; } 

然后是电话课

  @Entity @Table(name="table_phone") Class Phone{ @Id @GeneratedValue @Column(name="id_person") private Integer id; @Column(name="name") private String name; @ManyToOne @JoinColumn(name="id_person") private Person person; @Column(name="deleted") private int deleted; } 

我想要做的是实现软删除，将已删除项的已删除列插入值1，并为已有项插入值0。 我也希望级联我的删除，所以如果任何房间被删除，那么与该房间相关的每个人和电话也将被删除（“删除”列值设置为1）。 我的问题是如何在Hibernate上做到这一点？ 有没有优雅的方式来实现这些东西？

使用Hibernate实现软删除的最佳方法是在类上使用@SQLDelete注释。

确保您的映射设置为级联删除

调用session.delete（yourClass）应该实现软删除

Hibernate doc

 //used to overide the normal delete behavior @SQLDelete(sql="UPDATE (table_name) SET deleted = '1' WHERE id = ?") //optional Use this to exclude deleted element from get @Where(clause="deleted <> '1'") //OR (Filter may also be used if you need to load deleted items occasionally) @FilterDef(name="ProductFilter",defaultCondition="deleted <> 1 ")
