SSH整合，"sessionFactory " or "hibernateTemplate " is required异常
将ssh整合时，出现如下异常：

这里说少了sessionFactory或者是hibernateTemplate，这里是因为我在dao层里使用了HibernateDaoSupport来访问数据库，如其中一个类为：

我本以为要在这些类里加入sessionFactory就可以解决问题：
@Resource private org.hibernate.SessionFactory sessionFactory;
但是没有，还是报这个错，后来看了网上的解决方式 ，原因是spring.xml中没有加上default-autowire="byName" ，在注解的时候找不到实例化的sessionFactory，而注入了一个空的,在hibernate检查的时候就报那个错了。
spring配置文件加入byName的方式注入bean后，就可以正确使用注解了：
