java - 无法构建 EntityManagerFactory - Spring 和 Hibernate

Question

在使用 hibernate3 将 spring 应用程序部署到 glassfish 服务器 3.1.2 时，出现以下错误:

SEVERE: Exception while loading the app
SEVERE: log4j:ERROR LogMananger.repositorySelector was null likely due to error in class reloading, using NOPLoggerRepository.
SEVERE: Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in URL [file:/home/konrad/NetBeansProjects/webapp/experimental/SpringBar2012_1/SpringWebApp4/target/training/WEB-INF/classes/persistence-context.xml]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: webappPersistenceUnit] Unable to build EntityManagerFactory

有人可以帮我找出问题所在以及如何解决吗？

Answer 1

我不是专家，但我会尽力回答你的问题。

第一件事是您粘贴了错误堆栈跟踪的错误部分。深入挖掘并粘贴此错误的真正原因。

第二件事是您的持久性单元配置表明您将使用 JTA。

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

事实上您还没有指定JTA事务管理器。

有两种可能的解决方案:

• 将“transaction-type”更改为 RESOURCE_LOCAL，这样就不会使用 JTA
• 将 JTA 事务管理器配置添加到您的应用程序

尝试将 hibernate.transaction.manager_lookup_class 和 jta-data-source 添加到您的持久性单元:

<jta-data-source>...</jta-data-source>
<properties>
        ...
        <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.SunONETransactionManagerLookup" />
        ...
</properties>
