我有条件，一个问题可以有多个答案，在查询中，我传递问题ID以检索答案。
public List<TbDiscussionForumAnswere> findTbDiscussionForumAnswerebyforumQuestionId(Integer forumQuestionId) {
session = sessionFactory.getCurrentSession();
System.out.println("Before"+forumQuestionId);
List<TbDiscussionForumAnswere> tbDiscussionForumAnswereList = session
.createCriteria(TbDiscussionForumAnswere.class)
.add(Restrictions.eq("forumQuestionId.forumQuestionId", forumQuestionId)).list();
System.out.println("AFTER "+forumQuestionId);
return TbDiscussionForumAnswereList;
}
实体如下
@JoinColumn(name = "ForumQuestionId", referencedColumnName = "ForumQuestionId")
@ManyToOne
private TbDiscussionForumQuestion forumQuestionId;
另一个就像
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Basic(optional = false)
@Column(name = "ForumQuestionId")
private Integer forumQuestionId;
以下查询我在尝试获取数据时从hibernate获取
