SpringDaoSupport

@Component
public class SuperDAO extends HibernateDaoSupport {

	@Resource(name="sessionFactory")
	public void setSuperSessionFactory(SessionFactory sessionFactory) {
		super.setSessionFactory(sessionFactory);
	}

}

先上源代码：

@Component("logDAO")
public class LogDAOImpl extends SuperDAO implements LogDAO { 

	public void save(Log log) {

		//this.getHibernateTemplate().save(log);
		this.getHibernateTemplate().save(log);
		//throw new RuntimeException("error!");
	}

}

由于Super实现了HiberateSupportDao，又要为其注入hiberateTemplate 但直接注入会出问题，所以自定义了一个。在里面进行注入

setSuperSessionFactory
