Spring3.2+Hibernate4.1集成的时候提示找不到Session

Question

大家好， 我今天在整合spring3+hibernate的时候老是被提示找不到session  我获取session的方式是sessionFactory.getCurrentSession()

控制台报的错误：

严重: Servlet.service() for servlet springmvc threw exception

 以上就是这个项目的主要代码了 请各位大神帮我瞧瞧  多谢

Answer 1

org.springframework.orm.hibernate4.SpringSessionContext

注掉试试
