問題1，hql條件查詢報錯

執行Query session.createQuery(hql) 報錯誤直接跳到finally

解決方案

加入

<prop key="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</prop>

節點

加入之后再次報錯

org.hibernate.HibernateException: could not instantiate QueryTranslatorFactory: org.hibernate.hql.classic.ClassicQueryTransactionFactory

解決方案

修改成以下

<property name="hibernate.query.factory_class">org.hibernate.hql.internal.classic.ClassicQueryTranslatorFactory</property>

hql條件查詢

查詢最后一條數據

public RunTimePO getLast(String sin){Session session = sessionFactory.openSession();//System.out.println("22222222222222");String hql="from RunTimePO where SIN=? order by id desc"; //String hql="from RunTimePO where SIN=?";Query query = session.createQuery(hql); query.setString(0, sin);query.setMaxResults(1);//query.setInteger(0, 139); //int id=(Integer) query.uniqueResult();RunTimePO rp=(RunTimePO) query.uniqueResult(); if(rp!=null){System.out.println("id==="+rp.getId());}session.close();return rp; }

時間段查詢

public List<RunTimePO> getBetweenSeg(String sin,String startTime,String endTime){Session session = sessionFactory.openSession();String hql="from RunTimePO as u where SIN=? and u.date between ? and ?"; Query query = session.createQuery(hql);query.setString(0, sin);query.setString(1, startTime);query.setString(2, endTime);System.out.println(query.list().size());List<RunTimePO> runTimeList=query.list();return runTimeList;}

完成
