【中文标题】在相同的事务方法中使用 CriteriaBuilder JPA 插入和更新错误“外键不存在”【英文标题】：Insert and update with CriteriaBuilder JPA in the same transactional method thows error "Foreign Key not exist" 【发布时间】：2019-08-01 09:27:39 【问题描述】：我正在尝试插入并使用生成的实体更新同一事务中的 N 条记录。
出现“FK 不存在”错误，观察查询的日志跟踪以触发指令的相反顺序执行。
服务：
@Transactional
public Entity1 createEntity(Entity1 newEntity)
Entity1 inserted = dao.createEntity(newEntity);
Integer numUpdated = dao.updateEntity2(newEntity)
return inserted;
道：
public Entity1 createEntity(Entity1 newEntity)
this.em.persist(newEntity);
//now newEntity has PK
return newEntity;
public Integer updateEntity2(Entity1 newEntity)
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaUpdate<Entity2> uq = cb.createCriteriaUpdate(Entity2.class);
Root<Entity2> rootEntity2 = uq.from(Entity2.class);
uq.set(rootEntity2 .get(Entity2_.entity1), newEntity);
return em.createQuery(uq).executeUpdate();
实体：
@Entity
public class Entity1 implements Serializable
[...]
@OneToMany(mappedBy="entity1",fetch=FetchType.LAZY)
private List<Entity2 > entity2s;
[...]
@Entity
public class Entity2 implements Serializable
[...]
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="E1_ID")
private Entity1 entity1;
[...]
我们的想法是不必通过刷新来关闭事务，因为我知道将方法写为事务性应该允许这样做
这是跟踪日志：

【问题讨论】：
【参考方案1】：根据jpa 2.1的api
CriteriaUpdate 接口定义了执行批量的功能 使用 Criteria API 更新操作。条件 API 批量更新 操作直接映射到数据库更新操作，绕过任何 乐观锁定检查。使用批量更新的便携式应用程序 操作必须手动更新版本列的值，如果 需要，和/或手动验证版本列的值。 持久化上下文与批量更新的结果不同步。
CriteriaUpdate 对象必须有一个根。
JPA 2.1 Api
在某些示例中，他们手动管理事务性，在 catch 子句中使用 em.getTransaction().commit()、em.getTransaction().rollback() 等
