参考技术A 1、根据example批量查询某表中的信息

criteria使用总结

使用criteria查询not like某个字段时使用sqlRestriction

public List<CmsProgram> queryAllNews() {

DetachedCriteria criteria=DetachedCriteria.forClass(CmsProgram.class);

criteria.add(Restrictions.eq("delFlag", 0));

criteria.add(Restrictions.eq("isMain", 1));

criteria.add(Restrictions.sqlRestriction("PROGRAM_CODE not like ‘03%‘"));

criteria.add(Restrictions.sqlRestriction("PROGRAM_CODE not like ‘05%‘"));

criteria.addOrder(Order.asc("sortNo"));

return(List<CmsProgram>) this.hibernateTemplate.findByCriteria(criteria);

}

 

 

 

使用criteria查询{where（1 and 2）or (3 and 4)}

public List<Message> recycleBox(String id){

DetachedCriteria criteria = DetachedCriteria.forClass(Message.class);

criteria.add(Restrictions.or(Restrictions.and(Restrictions.eq("messageTo",id),Restrictions.eq("messageToFlag","1")),Restrictions.and(Restrictions.eq("messageFrom",id),Restrictions.eq("messageFromFlag","1"))));

criteria.addOrder(Order.desc("delDate"));

return (List<Message>) this.hibernateTemplate.findByCriteria(criteria);

 

}

 

排序

criteria.addOrder(Order.desc("createDate"));

criteria.addOrder(Order.asc("createDate"));

 

模糊查询               

criteria.add(Restrictions.like("bookBorrowerName", "%" + bookBorrowerName + "%"));

 

两者之间

criteria.add(Restrictions.between("bookBorrowingDate", startTime_date, endTime_date));

小于等于

criteria.add(Restrictions.le("bookBorrowingDate", end));

大于等于

criteria.add(Restrictions.ge("bookBorrowingDate", start));

小于

 criteria.add(Restrictions.lt("bookRebackDate", DateUtil.StringToDate(simpleDateFormat.format(new Date()), "yyyy-MM-dd")));

大于

criteria.add(Restrictions.gt("bookBorrowingDate", start));

在xx之间

 criteria.add(Restrictions.in("id", arr));

 

创建方式

Criteria criteria = hibernateTemplate.getSessionFactory().getCurrentSession().createCriteria(this.entityClass);

小生刚学，有什么不足，请大神指导，如果有人指导怎么用criteria多表查询，请指导，谢谢！
