spring hibernate配置默认使用resource_local还是jta？
我可以知道，因为我的配置是直接在 applicationContext.xml 上完成的，所以我没有 persistence.xml 。默认情况下这是resource_loca还是jta？如果我想使用jta，我需要添加额外的参数吗？

RESOURCE_LOCAL仅适用于 JPAEntityManager，不适用于 HibernateSessionFactory。 Hibernate 的 Spring 集成比与 JPA 的集成更加平滑，因此决定事务行为的唯一因素是您使用哪个事务管理器（HibernateTransactionManager或JtaTransactionManager） 。它可以与任何一个一起使用，而无需显式配置SessionFactory。RESOURCE_LOCALonly applies to JPAEntityManager, not to a HibernateSessionFactory. Hibernate's Spring integration is rather smoother than it is with JPA, and so the only thing that determines the transactional behaviour is which transaction manager you use with it (eitherHibernateTransactionManagerorJtaTransactionManager). It'll work with either one without you having to explicitly configure theSessionFactory.
