<!--

- PetClinic's central data access object: Hibernate implementation.

<property name="sessionFactory" ref="sessionFactory"/>

</bean>

<!--

- Transactional proxy for PetClinic's central data access object.

-

- Defines specific transaction attributes with "readOnly" markers,

- which is an optimization that is particularly valuable with Hibernate

- (to suppress unnecessary flush attempts for read-only operations).

-

- Note that in a real-life app with multiple transaction proxies,

- you will probably want to use parent and child bean definitions

- as described in the manual, to reduce duplication.

<!-- Hibernate 3.0's JMX statistics service -->

<!-- Implements the StatisticsServiceMBean management interface -->

<!--

<bean name="petclinic:type=HibernateStatistics" class="org.hibernate.jmx.StatisticsService">

<property name="sessionFactory" ref="sessionFactory"/>

</bean>-->

<!-- ========================= JMX EXPORTER DEFINITION ========================= -->

<!--

- Exporter that exposes Hibernate 3.0's statistics service via JMX.

- Autodetects the statistics service, which is a standard MBean,

- using its bean name as JMX object name.

-

- By default, the standard MBeanServerFactory.findMBeanServer method will be used

- to determine the MBeanServer. Unfortunately, this does not work on WebLogic <= 8.1:

- you need to comment in the WebLogicMBeanServerFactoryBean definition on WebLogic,

- specifying appropriate configuration values there.

-->

<!--

<bean id="jmxExporter" class="org.springframework.jmx.export.MBeanExporter">

<property name="autodetect" value="true"/>

</bean>-->

<!-- Comment the following in on WebLogic <= 8.1, which doesn't support -->

<!-- the standard MBeanServerFactory.findMBeanServer lookup mechanism. -->

<property name="server">

<bean class="org.springframework.jmx.support.WebLogicJndiMBeanServerFactoryBean"/>
