spring3+hibernate3(jpa) 如何配置多个数据源？（bean的配置管理是基于注解）

我在一个工程中用的是oracle和mysql，以下配置，现在还没有碰到问题：

        <property name="hibernateProperties">

            <value>

                hibernate.dialect=org.hibernate.dialect.MySQLMyISAMDialect

                hibernate.hbm2ddl.auto=none

                hibernate.show_sql=true

                hibernate.format_sql=false

            </value>

        </property>

    </bean>

    

    <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">

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

    </bean>

    

    <tx:annotation-driven transaction-manager="txManager"/>

</beans>

 

 

注入的时候用 @Resource指定名称：

 

@Resource(name="sessionFactory2")

private SessionFactory factory;

 

@Transactional(value="txManager2")

这个配置是两个事务，有没有办法做到只配置出一个事务呢
