mongdb分页 加多条件查询 完美好用

步骤一
@Override
public PageInfo paginationQuery(com.dearho.core.Page p, OrderQuery orderQuery, Class clazz) {
List<Sort.Order> orders = new ArrayList<Sort.Order>();

    //排序

// orders.add(new Order(Sort.Direction.DESC, “age”));
// orders.add(new Order(Sort.Direction.ASC, “num”));

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

    Criteria c1 = Criteria.where("isDel").is(false);
    list.add(c1);

    //订单编号
    if(StringUtil.isNotEmpty(orderQuery.getOrderNo())){
        Pattern pattern = Pattern.compile(".*?" + RgexUtils.escapeExprSpecialWord(orderQuery.getOrderNo()) + ".*");
        Criteria c2 =  Criteria.where("orderNo").regex(pattern);
        list.add(c2);
    }
    //司机手机号
    if(StringUtils.isNotEmpty(orderQuery.getDriverPhone())){
        Pattern pattern = Pattern.compile(".*?" + RgexUtils.escapeExprSpecialWord(orderQuery.getDriverPhone()) + ".*");
        Criteria c3 =  Criteria.where("driverPhone").regex(pattern);
        list.add(c3);
    }

        Criteria c4 =  Criteria.where("busNumber").regex(pattern);

    }
    //订单状态
    if(StringUtils.isNotEmpty(orderQuery.getState())){
        Pattern pattern = Pattern.compile(".*?" + RgexUtils.escapeExprSpecialWord(orderQuery.getState()) + ".*");
        Criteria c6 =  Criteria.where("state").regex(pattern);
        list.add(c6);
    }
    //运营平台

        Pattern pattern = Pattern.compile(".*?" + RgexUtils.escapeExprSpecialWord(orderQuery.getPlatform()) + ".*");
        Criteria c6 =  Criteria.where("platform").regex(pattern);
        list.add(c6);
    }
    if(StringUtils.isNotEmpty(orderQuery.getArea())){
        Pattern pattern = Pattern.compile(".*?" + RgexUtils.escapeExprSpecialWord(orderQuery.getArea()) + ".*");
        Criteria c6 =  Criteria.where("area").regex(pattern);
        list.add(c6);
    }


    orderQuery.setStartTime("2018-12-26");
    orderQuery.setEndTime("2018-12-28");
    orderQuery.setOrderNo("233");

    //订单时间
    if(StringUtils.isNotEmpty(orderQuery.getStartTime())&&StringUtils.isNotEmpty(orderQuery.getEndTime())){
        Criteria c3 =  Criteria.where("time").gte(orderQuery.getStartTime());
        Criteria c4 =  Criteria.where("time").lte(orderQuery.getEndTime());
        list.add(c3);
        list.add(c4);
    }


    PageInfo<Order> pageInfo =  orderDao.paginationQuery(mongoTemplate,p,orders,list,clazz);
    return  pageInfo ;
