java Hibernate：保存前刷新时违反约束
编辑1：在问题末尾添加了hibernate日志
编辑2： 这个问题与我的数据库有关。如果我从单元测试执行相同的方法（单元测试被配置为使用另一个DB），insert语句将通过。。。 有一件重要的事我还没有写：我正在开发一个基于模式的多租户系统。我目前有4个模式对应4个不同的客户端。我想我有两个或更多的FK约束指向同一个表。我现在正在往那边看
如果有人能想出一种方法来寻找字段上的重复FK约束，我很乐意阅读
=================================================== 原文：
Hibernate和JPA对我来说还是很新的，所以请容忍我
下面的代码没问题
PointAnalyse pointAnalyse = new PointAnalyse();
em.persist(pointAnalyse);
// em.flush();
ResourcesAnalyse resourcesAnalyse = new ResourcesAnalyse();
resourcesAnalyse.setPointAnalyse(pointAnalyse);
em.persist(resourcesAnalyse);
但是，如果我取消对em.flush()的注释或执行任何其他数据库操作（即使是简单的select查询），则在保存resourcesAnalyse实体时，我将得到一个ConstraintViolationException：
ERROR: une instruction insert ou update sur la table « ressources_analyse » viole la contrainte de clé
étrangère « fk_ressources_analyse_point_analyse_id »
Détail : La clé (point_id)=(1722) n'est pas présente dans la table « point_analyse ».]]
翻译：id为1722的FKpoint_id不存在于point_analyses表中
如果我跟踪Hibernate查询，我可以看到，在我试图保存resourceAnalyse对象之前，确实插入了一行具有这个ID的代码，所以应该不会有任何错误
以下是地图：
@Entity
@Table(name = "point_analyse")
public class PointAnalyse implements Serializable {
@Id
@SequenceGenerator(name = "POINT_ANALYSE_ID_GENERATOR", sequenceName = "POINT_ANALYSE_ID_SEQ", allocationSize = 1)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "POINT_ANALYSE_ID_GENERATOR")
@XmlElement
@Getter
@Setter
private Long id;
...
}
@Entity
@Table(name = "ressources_analyse")
@NoArgsConstructor
@Getter
@Setter
public class ResourcesAnalyse implements Serializable {
@Id
@SequenceGenerator(name = "RESSOURCES_ANALYSE_ID_GENERATOR", sequenceName = "RESSOURCES_ANALYSE_ID_SEQ", allocationSize = 1)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "RESSOURCES_ANALYSE_ID_GENERATOR")
private Long id;
@ManyToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "point_id")
private PointAnalyse pointAnalyse;
....
}
非常感谢您阅读本文，如果有人能解释我做错了什么
以下是hibernate日志的相关部分：

# 1 楼答案
em.flush（）或/和查询强制JPA执行SQL语句
我假设point_id有一个not null约束。因此，它尝试在未设置点_id的情况下执行insert语句
因此，在刷新或执行查询时，必须确保实体对象模型是一致的。或者必须删除not null约束
此外，如果必须存在非空约束，则应在多对一映射中添加optional=false
