java - Spring JPA TransactionManager 未找到

标签 java spring jpa

我有一个我认为是简单的项目，其中我使用 Spring 来管理 JPA，并使用 EclipseLink 作为我的持久性单元。我在前端使用 JavaFX，并将项目分为客户端模块、公共(public)模块和服务器模块。我正在使用 Maven 进行构建。这几天我一直在用头撞墙，试图弄清楚这一点。我尝试了不同的持久性单元配置和 servlet 配置，但似乎没有任何效果。而且错误似乎总是非常相似:事务管理器配置或使用中的某些内容值得怀疑。

非常感谢所有帮助。我是 Spring JPA 领域的新手，如果问题没有得到充分定义，请原谅。

这是我的 pom:

服务器和 IDE(我在其中启动客户端)之间的消息流量是:

"Could not open JPA EntityManager for transaction"

最佳答案 

Caused by: java.lang.ClassNotFoundException: org.springframework.transaction.CannotCreateTransactionException

创建交易时似乎出现错误。这可能是由于 persistance.xml 或 glassfish 配置文件中的配置错误造成的。

<persistence-unit name="NewTrialsPU" transaction-type="JTA">

EntityManagerFactory 无法从 JNDI 找到事务。我没怎么用过glassfish。但这应该是找到实际问题的线索。应该有某种方法来验证 JNDI 资源是否在 glassfish 中创建并相应地使用它。
