记录存在时的EntityNotFoundException,在更改表之后

标签: java hibernate jpa hibernate-onetomany

我有一个表(Records)与另一个表(ProgramTypes)有外键关系。该应用程序使用Hibernate-JPA,所以这通过使用@ManyToOne反映在代码中;记录表中的@JoinColumn标记,并在ProgramTypes表中具有外键约束和@OneToMany标记。

所以我对Records表进行了一些列更改,没有触及这个特定的约束,突然间我在检索数据时看到了以下类型的消息。

javax.persistence.EntityNotFoundException: Unable to find package.com.ProgramTypes with id {}

记录存在于数据库中,如果我替换映射

@ManyToOne
@JoinColumn(name="PRGRAMTYPESID", nullable=false)
private ProgramTypes programTypes;

private long programTypesId

有效。只是为了进一步混淆甚至我发现它在一定程度上的映射 - 在一个符合应用程序搜索条件的单个特定记录的情况下。我很困惑问题来自哪里,并会感谢任何帮助从中理解。

编辑 - 这是使用的查询

String queryBuild = "select rec from Records rec " + 
                "where rec.locationsId in (:locationsId) and rec.roles.code in (:roleList)";
            Query query = entityManager.createQuery(queryBuild);
            query.setParameter("locationsId", locationsIdList);
            query.setParameter("roleList", roleList);
            return query.getResultList();

这是stackTrace要求的。

答案 0 :(得分:4)

终于找到了麻烦的原因。在ProgramTypes中,有一个新列预期新的业务需求,在类中,它被映射到带有标记

的另一个表

@ManyToOne @JoinColumn(name="TYPESID", nullable=false)

但是没有设置某些类型的值,这导致了错误。一旦nullable设置为true,它就能正常工作。
