MongoDb如何添加查询条件

MongoDb如何添加查询条件

解决方法：

MongoCollection<Document> collection = MongoDb.getDb().getCollection(collect_name);//collection查询数据库的全部集合，再根据条件筛选

BasicDBObject match = new BasicDBObject();

match.put(1,1);

BasicDBObject[] array = {new BasicDBObject("sendtimesec", new BasicDBObject("$gte",beforeDate)),new BasicDBObject("sendtimesec", new BasicDBObject("$lt",afterDate)) };

match.put("$and",array);

BasicDBObject where = new BasicDBObject();

where.put("$match", match);

List<BasicDBObject> list=new ArrayList<BasicDBObject>();

list.add(where);

AggregateIterable<Document> aggregate = collection.aggregate(list);

MongoCursor<Document> iterator = aggregate.iterator();

while(iterator.hasNext()){//x循环获取满足条件的记录

Document document = iterator.next();

}
