问题出错的根本是:No CurrentSessionContext configured! (当然下边的错误解释肯定是很多的!)
表示:没有CurrentSession上下文配置! 这就想到了我们在利用CurrentSession的时候,其实就是getCurrentSession的时候没有在hibernate.cfg.xml文件中配置!
1、在 SessionFactory(会话工厂)启动的时候,Hibernate 会根据配置创建相应的 CurrentSessionContext,
在getCurrentSession()被调用的时候,实际被执行的方法是 CurrentSessionContext.currentSession()。
2、这里的“根据配置”就是如下配置:
* 如果使用的是本地事务(jdbc事务 本地事务:数据库只有一个)
<property name="hibernate.current_session_context_class">thread</property>* 如果使用的是全局事务(jta事务 全局事务:数据库有多个)
<property name="hibernate.current_session_context_class">jta</property>
