我正在尝试使用Hibernate在一个查询中获取大量数据。
我有这个名为查询：
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"左加入"的"加入"时，我只有匹配r.personne的行。但是有时候，R.Personne是无效的。因此，我决定使用"左联接"和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。但是我很确定这可能是一种做到这一点的方法吗？
这是我现在在代码中的关系：
@OneToMany(fetch = FetchType.EAGER)
@OrderBy(value = "NumReservation")
@JoinColumns({
@JoinColumn(name="NumReservation", referencedColumnName="NumeroReservation")
})
private List<Personnereservationlight> personne;
我成功地通过删除"加入"而获得所有保留灯，而无需persothne，并成功地将所有r.personne在另一个表中带有" join"的r.personne。但是当我放置"左JON"时，我不能同时在同一请求中。
有人有一个主意？
谢谢您的帮助

向您展示您尝试修改收集而无需任何交易，例如修复了以下代码
@Transactional
public ... methodToChangeCollection(...) {
// you code
}
更多信息，请参阅或此
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);
}
}
据我所知，您的实体Reservationlight_SS不是关系的所有者。这意味着您的实体Personnereservationlight的表具有Reservationlight_SS的外键。在这种情况下，您很可能希望将mappedBy元素与OneToMany注释一起使用。
如果您使用的是Spring，那么您还需要检查交易管理是否适当地在您的配置中使用@EnableTransactionManagement或<tx:annotation-driven/>。
在我的情况下问题是 FetchType.EAGER。
如果JPA存储库中的发现结合，则应将@Transactional与FetchType.LAZY结合使用
