Answer 1

在你继承HibernateSupportDao 的类中加入下面的方法@Resource(name="sessionFactory"); //这里用你在spring里面配置的sessionFactory的id
public void setMySessionFactory(SessionFactory sessionFactory){
    super.setSessionFactory(sessionFactory);
}

Answer 2

你的spring使用注解方式配置的 ，还是用xml
如果用xml配置的 。就在该been 上面加一个   <property>属性  ref 指向你的sessionFactory的id
