让我们想象一下场景：实体f1 = open('File 1')
f2 = open('File 2')
flag = True
for file1_line, file2_line in zip(f1, f2):
if file1_line[0] != file2_line[0]:
flag = False
break
print(flag)
和实体Company具有一对多双向关系。因此，实体Address将如下所示：
Address我要将这些代码迁移到@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
}
，其中Hibernate 4.3已弃用。当我尝试将CascadeType.DELETE_ORPHAN替换为CascadeType.DELETE_ORPHAN时，似乎orphanRemoval = true中甚至不存在orphanRemoval = true。
所以我的问题是：
@ManyToOne AddressHbm @Cascade(CascadeType.DELETE_ORPHAN)使用@ManayToOne会不正确？
如果@Cascade(CascadeType.DELETE_ORPHAN)在这里被滥用，将其删除是否有效？
