public void miseAJourTranscoIdCroisiere(Integer idCroisiereKaravel, String idCroisiereArmateur, TypeArmateur typeArmateur) {
IdCroisiereKaravelArmateur idRelationship = new IdCroisiereKaravelArmateur();
idRelationship.setIdCroisiereKaravel(idCroisiereKaravel);
idRelationship.setIdCroisiereArmateur(idCroisiereArmateur);
idRelationship.setTypeArmateur(typeArmateur);
entityManager.persist(idRelationship);
}
这个代码片段是否可以通过它的工作?它不会抛出异常。但它什么都没做。我不仅仅对Java中的持久性感到困惑。
由于我无法使用hql插入...值,我应该直接使用jpa,对吧?
我试过in this way但我得到了这个

所以我考虑创建另一个EntityManager来执行此操作。但是,它不是一个我不能使用EntityManagerFactory的静态方法。
在ddbb中进行简单插入可能会非常麻烦吗?
如果我说愚蠢或混合概念,我很抱歉,但我有两天的Java持久性和Hibernate经验。
编辑以显示我的课程:
我需要一个交易,但我无法从共享的EntityManager获得它(这意味着什么?)
我是否只需要一个EntityManager?如果我这样做,我就不能使用EntityManagerFactory来保持静态。
对不起,我不是在创建这种架构。我刚刚开始使用Spring和Hibernate,所以这里有一个很大的组合...

答案 0 :(得分:4)
看起来您的问题很简单:它想要一个交易。你正在使用Spring。将Spring拖入持久性领域的主要原因是获得基于AOP的注入事务..?您应该能够注释您的方法@Transaction,并在您的applicationContext.xml或其他一些引导程序中启动TransactionManager。
答案 1 :(得分:2)
是的,EntityManager#persist
应该可以保存记录,
您的实体管理器持久化似乎在try catch Block中抛出运行时异常包装
确保您的类在spring transaction下声明,如果您使用基于Annotation的配置,那么您的类应标记为@Transactional,您的entityManager应标记为@PersistenceContext
答案 2 :(得分:1)
正如问题的原始海报所述:
实际上没有正确设置TranscationManager的bean。我在Spring配置文件中找到了第一个。由于审计系统工作正常,我只使用了相同的配置。但是,对于其他DDBB访问,它尝试使用Audit TransactionManager(出现在配置文件中的第一个)
我希望这有助于某人。很抱歉这样一个模糊的解决方案,但这是几个月前,我无法再访问代码了。
