java - Hibernate 事务的 session 问题

标签 java hibernate spring transactions

我是 hibernate 新手，并尝试将 hibernate 与现有的基于 spring 的应用程序集成。

我配置了 session 工厂和事务管理器、事务代理模板。

我还在这个应用程序中使用 Quartz 调度程序。

当我运行该应用程序时，出现以下异常。

错误 au.com.michaelpage.ctsgui.utils.OrganizationMergeProfileThread - 更新机会时出错:无法打开 Hibernate session 进行事务；嵌套异常是 java.lang.IllegalStateException:键 [weblogic.jdbc.common.internal.RmiDataSource@32b034] 的值 [org.springframework.jdbc.datasource.ConnectionHolder@9f6885] 已经绑定(bind)到线程 [DefaultQuartzScheduler_Worker-0]

我的 hibernate session 配置:

 <bean id="sessionFactoryAU"
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource">
        <ref bean="profileAU" />

我的 Quartz 调度程序配置:

<bean id="organisationMergeJobDetail"
    class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="organisationMergeJob" />
    <property name="targetMethod" value="execute" />
    <property name="concurrent" value="false" />
</bean>

<bean id="organisationMergeProfileRegularCheckerTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean">
    <property name="jobDetail" ref="organisationMergeJobDetail" />
    <property name="repeatInterval">
        <util:constant static-field="au.com.michaelpage.ctsgui.common.Constants.CHECK_FREQUENCY" />
    </property>
</bean>

这是“organizationMergeJob”的 bean 定义

<bean id="organisationMergeJob" class="au.com.michaelpage.ctsgui.utils.OrganisationMergeProfileThread"> 
   <property name="organisationMergeMgr" ref="organisationMergeMgr"/> 
</bean>

<bean id="organisationMergeMgr" class="au.com.michaelpage.ctsgui.mgr.OrganisationMergeMgrImpl">  
    <property name="organisationMergeDao" ref="organisationMergeDao"/>   
</bean>

有什么办法可以解决这个问题吗？

提前谢谢您。

嗨斯卡夫曼，

这是错误的堆栈跟踪:

谢谢。

这是“organizationMergeMgr”的 bean 定义

<bean id="organisationMergeMgr" 
   class="au.com.michaelpage.ctsgui.mgr.OrganisationMergeMgrImpl">
   <property name="organisationMergeDao" ref="organisationMergeDao"/>
</bean>

最佳答案

我想查看organizationMergeMgr的代码，但我的猜测是，您的事务在不应该的情况下保持打开状态，因为在所有情况下都没有进行显式的提交或回滚调用(即使您认为它将始终参与更大的事务，必须进行这些调用以保证事务资源的清理)
