hibernate中Criteria对象的语法

在使用hibernate的查询对象进行编辑查询条件时，罗列一些简单的语法代码：

//添加用户名不等于admin的条件
criteria.add(Restrictions.not(Restrictions.eq("roleName",SYSTEM_ADMIN_ROLE_NAME)));
//添加按照修改时间进行倒序排列
criteria.addOrder(Order.desc("updateTime"));
//模糊查询  ilike忽略大小写  like不忽略大小写  ANYWHERE是设置位置
criteria.add(Restrictions.ilike("voiceNumber",voiceNumber, MatchMode.ANYWHERE));

查询表中指定的列时：

//获取查询对象
Criteria criteria = getSession().createCriteria(TopicClassification.class);
//创建查询字段列表
ProjectionList projectionList = Projections.projectionList();
projectionList.add(Projections.property("uuid"));
//添加查询条件
criteria.setProjection(projectionList);

将结果去重

//将结果去重
criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);

分页查询

//设置查询总页数
criteria.setProjection(Projections.rowCount());
//添加排序条件
criteria.addOrder(Order.desc("updateTime"));
//添加分页条件
criteria.setFirstResult(startSize);
criteria.setMaxResults(pageSize);

>	Restrictions.gt()	大于greater than
>=	Restrictions.ge()	大于等于greater than or equal
<	Restrictions.lt()	小于less than
<=	Restrictions.le()	小于等于less than or equal
is null	Restrictions.isnull()	等于空值
is not null	Restrictions.isNotNull()	非空值
like	Restrictions.like()	字符串模式匹配
and	Restrictions.and()	逻辑与
and	Restrictions.conjunction()	逻辑与
or	Restrictions.or()	逻辑或
or	Restrictions.disjunction()	逻辑或
not	Restrictions.not()	逻辑非
in(列表)	Restrictions.in()	等于列表中的某一个值
not in(列表)	Restrictions.not(Restrictions.in())	不等于列表中任意一个值
