Java 使用相同数据源的transactionmanager

（连接到db call abc）--->datasource1-->LocalSessionFactoryBean-->transactionManager1

（连接到db call abc）--->datasource1-->AnnotationSessionFactoryBean-->TransactionManager 2

我之所以有两个sessionfactory，是因为第三方osworkflow库使用了一个sessionfactory，而我的应用程序使用了后者

由于两者都连接到相同的“数据源1”（相同的数据库），我可以使用其中一个作为服务层transactionmanager，对吗

使用一个

SessionFactory

---

AnnotationSessionFactoryBean

扩展了

LocalSessionFactoryBean

，因此它拥有所有功能。

原因是第三方osworkflow使用.hbm映射，而我的应用程序使用注释映射。如何组合成一个？只需使用AnnotationSessionFactoryBean。它具有LocalSessionFactoryBeanI的功能，因为您没有使用jpa（EntityManagerFactory），所以将“jpa”改为“hibernate”
