@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
