当java应用于@manytone时，Hibernate@Cascade（CascadeType.DELETE_ORPHAN）是否正确？

Question

让我们想象一下场景：实体Company和实体Address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
}

我将把这些代码迁移到Hibernate 4.3，其中CascadeType.DELETE_ORPHAN已被弃用。当我试图用orphanRemoval = true替换CascadeType.DELETE_ORPHAN时，似乎orphanRemoval = true在@ManyToOne中根本不存在

所以我的问题是：

• AddressHbm在@ManayToOne中是否错误地使用了@Cascade(CascadeType.DELETE_ORPHAN)

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