java - 如何@SQLDelete、软删除、具有组合键的实体

Question

如何获取@SQLDelete中的复合键片段来执行实体的软删除？

@Data
class DummyKey {
    private Long foo;
    private Long bar;
}


@IdClass(DummyKey.class)
@SQLDelete(sql = "UPDATE dummy SET deleted = 'Y' WHERE ???") //how to get key params
@Where(clause = "deleted='N'")
class Dummy {
    @Id
    @Column(name = "foo")
    private Long foo;
    @Id
    @Column(name = "bar")
    private Long bar;

    @Column(name = "stuff")
    private String stuff;

    @Column(name = "deleted")
    private String deleted;
}

Answer 1

复合 ID 的值按照 IdClass 属性的顺序绑定(bind)到准备好的语句，因此这应该有效:

@SQLDelete(sql = "更新虚拟集已删除 = 'Y' WHERE foo=? AND bar=?")

( AbstractEntityPersister 将绑定(bind)委托(delegate)给标识符类型，因此在本例中为 ComponentType ，它在 AbstractComponentTuplizer 的帮助下迭代属性)
