hibernate的查询语句实例

记录写过的Dao语句 有HQL的 有SQL的 有Criteria的

@Repository
public class GuahaoManagerDaoImpl extends HibernateDaoSupport implements GuahaoManagerDao {
    @Autowired
     public void setsessionFactory(SessionFactory sessionFactory){
        super.setSessionFactory(sessionFactory);
    }

    public void addGuhao(GuahaodanEntity guahaodanEntity) {
        this.getHibernateTemplate().save(guahaodanEntity);// TODO Auto-generated method stub

    }
    public GuahaodanEntity findById(int id) {
        return (GuahaodanEntity) this.currentSession()
                .createQuery(
                        "from GuahaodanEntity where id = ? and isused = true")
                .setParameter(0, (Integer)id).uniqueResult();
    }

    @Override
    public List<GuahaodanEntity> findAll(int begin, int pageSize) {
        DetachedCriteria detachedCriteria=DetachedCriteria.forClass(GuahaodanEntity.class).add(Restrictions.eq("isused",true));
        List<GuahaodanEntity> guahaodanEntities= (List<GuahaodanEntity>) getHibernateTemplate().findByCriteria(detachedCriteria,begin,pageSize);
        return guahaodanEntities;
    }

    @Override
    public List<GuahaodanEntity> findAllCount() {
        DetachedCriteria detachedCriteria=DetachedCriteria.forClass(GuahaodanEntity.class).add(Restrictions.eq("isused",true));
        List<GuahaodanEntity> guahaodanEntities= (List<GuahaodanEntity>) getHibernateTemplate().findByCriteria(detachedCriteria);
        return guahaodanEntities;
    }

    @Override
    public void modifyGuhao(GuahaodanEntity guahaodanEntity) {
        this.getHibernateTemplate().saveOrUpdate(guahaodanEntity);
    }


    public void delGuhao(int id) {
        this.getHibernateTemplate().delete(getSessionFactory().getCurrentSession().createCriteria(GuahaodanEntity.class).add(Restrictions.eq("id",id)).uniqueResult());
    }
}
