java - Hibernate @Cascade(CascadeType.DELETE_ORPHAN) 在应用于@ManyToOne 时是否正确？

Question

让我们想象一下场景：EntityCompany和 EntityAddress具有一对多的双向关系。所以实体Address看起来像：

@Entity
@Table(name = "address")
public class AddressHbm{

    @Id
    @GeneratedValue(generator = "id-generator")
    @Column(name="address_id")
    private long id;

    @ManyToOne(cascade = {CascadeType.PERSIST, CascadeType.MERGE} )
    @Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
    @JoinColumn(name="company_id")
    private Company company = null;

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

    // other properties and methods
}

我要将这些代码迁移到不推荐使用的Hibernate 4.3地方CascadeType.DELETE_ORPHAN。当我试图用 替换CascadeType.DELETE_ORPHAN时orphanRemoval = true，它似乎orphanRemoval = true甚至不存在于@ManyToOne.

所以我的问题是：

• AddressHbm使用不@Cascade(CascadeType.DELETE_ORPHAN)正确@ManayToOne？

• 如果@Cascade(CascadeType.DELETE_ORPHAN)在这里被误用，是否只删除它有效？
