Question

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);
    }

这个代码狙击手应该用它来操作吗? 它没有例外。但是它什么也不做。我和爪哇的持久性非常混为一谈。

既然我不能插入... 数值与hql,我应该做它直接与jpa,对不对?

我试图这样做,但我得到了这个

于是我考虑为这样做而另设一个实体经理人。但是,我无法使用实体管理工具,这不是一个静态的方法。

能这么乱吗? 把一个简单的插插在三角帆上?

我很抱歉如果我说愚蠢或我混合概念, 但我有两天的经验在爪哇持久性和休眠。

<强度> 编辑显示我的班级 :

我确实需要一笔交易, 但我不能从共同实体管理者那里得到这笔交易(这意味着什么? )

我需要一个实体管理者来做这个方法吗? 如果我需要,我就不能使用实体管理工具作为静态。

对不起,这建筑不是我创造的,我刚从春天和休眠开始,所以这里有一大堆东西要给我...

Answer 1

正如问题原海报上所说的:

My solution:

事实上, TranscationManager 的豆类没有正确设置。我选择了在 Spring 配置文件中发现的第一个豆类。由于审计系统运作良好, 我刚刚使用了同样的配置。但是, 对于其他的 DDBB 访问, 它试图使用审计交易管理器( 首个出现在配置文件中) 。

但几个月前的事了,我无法再使用密码了。

Answer 2

看起来你的问题很简单: 它想要一个交易。您正在使用 Spring 。将 Spring 拖入持久性域的主要原因是要获得 AOP 的注射交易。? 您应该能够批注您的方法@ Transaction 并启动交易管理器, 无论是在您的应用程序Context. xml 中, 还是通过其他的陷阱。

Answer 3

是的, EntyManager #persist 应该能够保存记录,

您的实体经理似乎一直坚持正在扔运行时间例外把它包起来尝试抓捕布洛克
如果您正在使用基于批注的配置, 确保在春季交易中宣布您的类别, 那么您的类别应该被标记为@ Transactional, 您的实体管理器应该被标记为@ PersistenceContext
