Mongodb高級查詢Aggregation聚合組件分頁

用Mongo的聚合組件Aggregation要用到兩個方法skip和limit。skip設置起點（分頁的時候不包含起點，從起點的下一行開始），limit設置條數。如:

Aggregation.skip(10),

Aggregation.limit(20)的意思是（10,20）第10條以後取20條數據。

    	Criteria criteria= new Criteria();
    	if(map.get("userlist")!=null&&!"".equals(map.get("userlist"))){
    		List<UserPrivacy> userList =(List<UserPrivacy>) map.get("userlist");
    		criteria.and(Field.USERPRIVACY).in(userList);
    	}
    	Order orders = new Order(Direction.DESC,Field.CREATE_TIME);
    	Sort sort = new Sort(orders);
        TypedAggregation<OrderReport> aggregation = Aggregation.newAggregation(OrderReport.class,
                Aggregation.match(
                		criteria

//                                .and(Field.START_TIME).gte(startTime).lte(endTime)
                ),
                Aggregation.group(Field.VIPSERVICE)
                		.first(Field.VIPSERVICE).as(Field.VIPSERVICE)
