我正在尝试使用休眠条件将附加条件添加到Join子句中.实际上,有一些方法可以做到这一点：

createCriteria(String associationPath, String alias, int joinType, Criterion withClause)

和

createAlias(String associationPath, String alias, int joinType, Criterion withClause) 

他们与一对一和一对多关系正常工作.但是,当我尝试将它们用于具有多对多关系的实体时,出现以下错误：

Caused by: org.postgresql.util.PSQLException: No value specified for parameter 1.

有谁能够帮助我？
粗鲁的示例如下：

@Entity
public class Person {

@Id
@GeneratedValue
private Long id;

@ManyToMany
private Set<PersonName> names;

}

public class PersonName {

@Id
@GeneratedValue
private Long id;

@Column
private String name;

}
public class PersonDao extends HibernateDaoSupport {

public List<Person> findByName() {
    Criteria criteria = getSession().createCriteria(Person.class, "p");
    criteria.createCriteria("p.names", "names", JoinType.INNER_JOIN, Restrictions.eq("name", "John"));
    return criteria.list();
}
}

正在生成的查询是

select this_.id as y0_ from person this_ 
    inner join debtor_info this_1_ on this_.id=this_1_.id 
    left outer join person_person_name personname3_ on this_.id=personname3_.person_id and ( name1_.name=? ) 
    left outer join person_name name1_ on personname3_.person_name_id=name1_.id and ( name1_.name=? )

如您所见,联接条件被添加了两次,这显然是不正确的

提前致谢.

顺便说一句我正在使用PostgreSQL 9,Hibernate 3.6.3

解决方法:

这是一个HHH-7355
Hibernate criteria JOIN + additional condition (with clause) don’t work with many-to-many association的错误,并且由于Hibernate Criteria API已被弃用,您应该使用JPA Crtiterias,因此不会得到修复.
您可以尝试使用HQL with clause

from Cat as cat
left join cat.kittens as kitten
    with kitten.bodyWeight > 10.0
