@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
