Spring4整合Hibernate4出现的错误的解决

今天在使用Spring4整合Hibernate4过程当中出现错误

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

错误的缘由是因为hibernate4修改了hibernate3中 getCurrentSession()方法的支持，须要在service层注解@Transactional

具体的代码以下：

Spring-hibernate.xml

而后在Service层添加@Transactional注解便可
