spring和hibernate 基础的增删改

Posted 2020-10-02

所有的dao层可以有个superDao

比如：BaseHibernateDao

继承的类是hibernate4

public class BaseHibernateDao extends HibernateDaoSupport{

　　@Resource(name="jsbcTemplate")

　　protected JdbcTemlate jdbcTemplate;

　　@Resource(name="sessionFactory")

　　public void setSF(SessionFactory sessionFactory){

　　　　this.setSessionFactory(sessionFactory);
　　}

}

 

其他dao层继承这个baseDao就行了,例如：其他dao

@Repository
public class PlatUserDao extends BaseHibernateDao{
          public void savePlatUser(PlatUser platUser){
                this.getHibernateTemplate().saveOrUpdate(platUser);
          }

          public List<PlatUser> getPlatUserList(){
                List<PlatUser> results=null;
                results=getHibernateTemplate().execute({
                     @override
                     public List<PlatUser> doInHibernate(Session session) throws HibernateException{
                        String hql="from PlatUser p order by p.id desc";
                        Query query =session.createQuery(hql);
                        return query.list();
                     }
                });
               return results;
          }
}
