1、 description: use combined and and or query in the mongo
2、sql query statement:
select * from deviceInfo where devId='11010001' and (sndStatus=0 or sndCount >= 3);
3、match mongo sql query:
db.getCollection("deviceInfo").find({ "devId" : '11010001', "$and" : [{ "$or" : [{ "sndStatus" : 0 }, { "sndCount" : { "$gte" : 3 } }] }] })
4、code example:
   /*
    * use combined and and or query in the mongo
    * match mongo sql query:
    * 
     public void queryAndOrOperator() {
   	    Criteria criteria = Criteria.where("devId").is('11010001');
        Criteria orCriteria1 = Criteria.where("sndStatus").is(0);
    	Criteria orCriteria2 = Criteria.where("sndCount").gte(3);
	    Criteria orAllCriteria = new Criteria().orOperator(orCriteria1, orCriteria2);
        criteria.andOperator(orAllCriteria);
        Query query = Query.query(criteria);
        List<MongoDatabaseEntity> queryList = mongoTemplate.find(query, MongoDatabaseEntity.class);
