mongo:Criteria和Query

Query query=new Query();
Criteria criteria=Criteria.where("name").is("tom").and("studentNum").in(numberList);
query.addCriteria(criteria);

或new Query(criteria);

Criteria criteria=Criteria.where("indexWarnGrade").ne("0").orOperator(Criteria.where("resId").is(channelId),Criteria.where("resBelongChannelId").is(channelId));
query.addCriteria(criteria);
query.with(new Sort(Direction.DESC, "indexWarnLatelyDate"));

//分页
int currentPage = (initPagingBean.getStart()/initPagingBean.getPageSize())+1;
Query query=new Query();
		//查询通道和通道下属的设备告警信息
		Criteria criteria=Criteria.where("indexWarnGrade").ne("0").orOperator(Criteria.where("resId").is(channelId),Criteria.where("resBelongChannelId").is(channelId));
		query.addCriteria(criteria);
		query.with(new Sort(Direction.DESC, "indexWarnLatelyDate"));
		int total = (int) this.realMongodbServiceImpl.findCount(MonitorObject.class, query);
		initPagingBean.setTotalItems(total);
		//查询mo集合
		List moList=this.realMongodbServiceImpl.findList(MonitorObject.class, query, currentPage, initPagingBean.getPageSize());		

initPagingBean.setDataList(wvList);
return  initPagingBean;

//is相当于等于
//in相当于sql中的in
//ne相当于不等于
//orOperator接受多个条件，组成or逻辑
