[英]hibernate: How to map a variable as foreign key
is it possible to declare a variable Long documentID
as Foreign key instead of the natural Document document
?Below the example: 在下面的示例中,是否可以将变量
Long documentID
声明为外键而不是自然Document document
?
@Entity
@Table("document")
class Document{
...
@Id
Long id;
...
}
@Entity
@Table("something")
class Something{
....
//instead of
@ManyToOne
Document document;
// this one with the appropriate annotations
Long documentID;
...
}
Thanks in advance.... 提前致谢....
It seems a similar question have already appeared: Hibernate. 似乎已经出现了类似的问题: 休眠。 Foreign key mapping by id
按ID映射外键
It is not recommended to work with hibernate in such manner. 不建议以这种方式使用休眠模式。
