我正在尝试使用 Hibernate 在一次查询中获取大量数据。
我有这个命名查询:
SELECT r FROM Reservationlight_SS r LEFT JOIN r.personne p WHERE
r.iDSport =:IDSport AND r.iDSaison =:IDSaison AND
r.dateReservation =:date GROUP BY r.numeroReservation, r.heureDebutReservation, r.iDTerrain
当我使用“JOIN”而不是“LEFT JOIN”时，我只有与 r.personne 匹配的行。 但有时，r.personne 为空。所以我决定使用“LEFT JOIN”，Hibernate 给我这个错误:
org.hibernate.HibernateException: collection is not associated with any session
我尝试搜索是否可以将 @OneToMany 作为可选，但这是不可能的。但我很确定这可能是一种方法，不是吗？
这是我现在代码中的关系:
@OneToMany(fetch = FetchType.EAGER)
@OrderBy(value = "NumReservation")
@JoinColumns({
@JoinColumn(name="NumReservation", referencedColumnName="NumeroReservation")
})
private List<Personnereservationlight> personne;
通过删除“JOIN”，我成功地获得了没有人员的所有 Reservationlight_SS，并且通过“JOIN”成功地获得了另一个表中具有 r.personne 的所有 Reservationlight_SS。但是当我放置“LEFT JOIN”时，我不能将两者放在同一个请求中。
有人有想法吗？
感谢您的帮助

最佳答案
大多数情况下异常(exception)
org.hibernate.HibernateException: collection is not associated with any session
向您展示您尝试在没有任何事务的情况下修改集合，并修复了以下代码
@Transactional
public ... methodToChangeCollection(...) {
// you code
}
更新:
您可以尝试手动使用事务，例如:
public List<Reservationlight_SS> getAllReservationByDate(Integer idSport, Integer idSaison, Date date) {
try{
EntityManager em = getEntityManager();
em.getTransaction().begin();
List<Reservationlight_SS> result = em.createNamedQuery("getAllReservationByDateSS").setParameter("IDSport", idSport).setParameter("IDSaison", idSaison).setParameter("date", date).getResultList();
em.getTransaction().commit();
return result;
}catch(Throwable th){
System.out.println(th.getMessage());
throw new SportReservExceptions(getClass().getName() + " -> " + th);
}
}
关于java - @OneToMany 导致集合不与任何 session 关联，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44835582/
