,其中Answer
包含一个List<String>
.

with contains a class Answer
with Answer
containing a List<String>
.
Hibernate是否可以使用注释映射List<String>
?我的意思是,因为它没有@Entity
注释?
Is a List<String>
mappable by Hibernate using annotations? I mean, since it does not have the @Entity
annotation?

答
使用@ElementCollection
:
@ElementCollection
@CollectionTable(name="Nicknames", joinColumns=@JoinColumn(name="user_id"))
@Column(name="nickname")
public List<String> getNicknames() { ... }
