目前软删除实现看起来像这样

父类

@MappedSuperclass
public abstract class ParentClass {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    protected Long id;

    private boolean archived = false;
}

儿童等级1

@Entity
@SQLDelete(sql = "UPDATE child_class1 SET archived = 1 WHERE id = ?")
@Where(clause = "is_archived = 'false'")
public class ChildClass1 extends ParentClass {
    ...
    ...
}

儿童班2

@Entity
@SQLDelete(sql = "UPDATE child_class2 SET archived = 1 WHERE id = ?")
@Where(clause = "is_archived = 'false'")
public class ChildClass2 extends ParentClass {
    ...
    ...
}

正如您所见，SQLDelete＆amp;哪些条款重复，查询中的细微差别。有没有办法概括它们并能够将它们放在ParentClass中？

之类的东西

@MappedSuperclass
@SQLDelete(sql = "UPDATE <what_would_come_here> SET archived = 1 WHERE id = ?")
@Where(clause = "is_archived = 'false'")
public abstract class ParentClass {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    protected Long id;

    private boolean archived = false;
}

我确实尝试过上述更改，但是hibernate没有在获取或删除实体上应用这些注释。

Hibernate用超类实现软删除
