标签： java spring hibernate java-ee

我正在使用Hibernate 4和Spring 3.

我的应用程序正在运行并正确地在数据库中插入/更新数据。一旦插入/更新完成，我将在一段时间内完成以下异常：

我在网上搜索并发现：如果没有关闭连接，可能会出现此错误。但是我在这里使用@Transactional。我需要在这里关闭任何东西。

请建议。

添加root-context.xml 

<!-- <tx:annotation-driven transaction-manager="transactionManager" /> -->
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
     <tx:annotation-driven transaction-manager="transactionManager"/>
<context:component-scan base-package="com.abc" />
        <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <!-- <property name="dataSource" ref="dataSource" /> -->
        <property name="configLocation">
            <value>classpath:hibernate.cfg.xml</value>
        </property>

</beans>
