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

    @Qualifier("sessionFactory")
    private SessionFactory sessionFactory;
    
    public Session getSession() {
        return sessionFactory.getCurrentSession();
    }

}

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
