我试图从Hibernate 3.5升级项目到Hibernate 4.2，但现在我在Spring上下文初始化（我们正在使用Spring 3.2.2）。升级到休眠4：org.hibernate.TransactionException：无法提交JDBC连接
您可以在下面找到我们的配置。
任何想法是什么可以是异常的原因？ 将休眠版本还原为3.5，异常消失。

在初始化Quartz调度程序bean期间发生异常。这是我们的配置：
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"
name="CLUSTERED_Scheduler" lazy-init="true">
<property name="dataSource" ref="dataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="overwriteExistingJobs" value="false" />
...
</bean>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
p:dataSource-ref="dataSource"
p:persistenceXmlLocation="classpath:persistence.xml">
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"
p:database="${jpa.database}"
p:showSql="${jpa.showSql}"
p:generateDdl="${jpa.generateDdl}"
p:databasePlatform="${jpa.databasePlatform}" />
</property>
</bean>
<bean id="transactionManager" name="npp"
class="org.springframework.orm.jpa.JpaTransactionManager"
p:entityManagerFactory-ref="entityManagerFactory"
p:dataSource-ref="nppDataSource"
/>
这是persistence.xml中的内容：
<persistence xmlns="http://java.sun.com/xml/ns/persistence"

xsi:schemaLocation="http://java.sun.com/xml/ns/persistence

<persistence-unit name="punit" transaction-type="RESOURCE_LOCAL">

<class>...</class>
...
<properties>
<property name="hibernate.ejb.interceptor"
value="my.Interceptor" />
</properties>
</persistence-unit>
</persistence>
