org.hibernate.HibernateException: Could not obtain transactionsynchronized Session for current thread

• hibernate 执行插入修改删除需要事务操作

org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread

	at org.springframework.orm.hibernate5.SpringSessionContext.currentSession(SpringSessionContext.java:142)
	at org.hibernate.internal.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:495)
	

• 解决添加事务
• spring核心配置文件添加 <tx:annotation-driven/>
• 持久层添加 @Transactional
• 使用 Session session = sessionFactory.getCurrentSession(); 获取 Session。
