2.原因
项目中所有Dao实现类都继承了HibernateDaoSupport接口，如果Dao或配置文件中没有'sessionFactory' 或者'hibernateTemplate'就会报错，由于我使用的是spring的annotation注入，HibernateDaoSupport不能注入sessionFactiry和hibernateTemplemet。
3.解决方法：在Dao中添加下面这个方法即可解决
@Resource
public void setSessionFacotry(SessionFactory sessionFacotry) {
super.setSessionFactory(sessionFacotry);
}
