利用hibernate查询语句查询信息，默认当日，否则往前推

public List<AhemcQualityAir> selectcheckQualityAir(final String time) {final String hql= "select air from AhemcQualityAir air where air.isDelete=0 and air.strtes1=1 and air.reportDate=? order by  air.cityname asc";List<AhemcQualityAir> list = getHibernateTemplate().executeFind(new HibernateCallback() {public Object doInHibernate(Session session)throws HibernateException, SQLException {List<AhemcQualityAir> list = null;Query query = session.createQuery(hql);//for (int i = 0; i >-10; i--) {String time1=DateUtil.calculateDateByNumber(i);query.setDate(0, DateUtil.stringToUtilDate(time1));list = query.list();if (list != null && list.size() > 0) {break;}}return list;}});return list;}
