(连接到db call abc)---> datasource1 ---> LocalSessionFactoryBean ---> transactionManager1
(连接到db call abc)---> datasource1 -----> AnnotationSessionFactoryBean - > transactionManager2
我有2个sessionfactory的原因是因为一个被第三方osworkflow库使用而后者被我的应用程序使用
由于两者都连接到相同的“datasource1”(同一个数据库),我可以使用其中任何一个作为服务层事务管理器吗?
<bean id="annotatedsessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="packagesToScan" value="com.company.model" >

答案 0 :(得分:1)
使用一个SessionFactory
AnnotationSessionFactoryBean
扩展LocalSessionFactoryBean
,因此它具有所有功能。
