想要在一个休眠标准中添加两个不同的表（类）

want to add two different tables(classes) in one hibernate criteria

我有这个密码

1

ArrayList<String> city = 'Anniston';

Criteria crit = session.createCriteria(CandidateResumeInfo.class);
crit.add(Restrictions.eq("resumeSearchable", 1));

现在我想添加以下条件

crit.add(Restrictions.in("cities", city));。

但问题是，cities列不在CandidateResumeInfo.classITS的candidateinfo类中。

任何关于如何在上面的标准中添加这个标准，以及如何在上面的标准中添加CandidateInfo类的想法。

我想我需要连接或链接这两个表，但是如何，实体类中会有什么变化吗？

这是我的两个班

有从CandidateResumeInfo到CandidateInfo的多对一关联。

在CandidateResumeInfo类中添加新成员，比如，

1
2
3
4
5

@ManyToOne()
@JoinColumn(name ="candidate_userId")
private CandidateInfo candidateInfo;

// Also add getters and setters

号

现在在查询中，添加一个新别名，

1 2	crit.createAlias("candidateInfo","candidateInfo"); crit.add(Restrictions.in("candidateInfo.city", city));

你需要像这样添加关系

1
2
3
4

@ManyToOne(cascade = CascadeType.ALL)
public CandidateResumeInfo getCandidateResumeInfo () {
return this.candidateResumeInfo ;
}
