查询列表可筛选可模糊查询的写法

作者:互联网

框架:mybatis-plus

 1 @Override
 2     public OrderListPageDto listOrder(OrderListVo orderListVo) {
 3         //返回值
 4         OrderListPageDto result = new OrderListPageDto();
 5         //页面对象
 6         Page<Order> orderPage = new Page<>();
 7         orderPage.setSize(orderListVo.getPageSize());
 8         orderPage.setCurrent(orderListVo.getPageIndex());
 9         QueryWrapper<Order> orderQueryWrapper = new QueryWrapper<>();
10         //从vo拿筛选条件
11         String status = orderListVo.getStatus();
12         String serviceType = orderListVo.getServiceType();
13         String createTimeBegin = orderListVo.getCreateTimeBegin();
14         String createTimeEnd = orderListVo.getCreateTimeEnd();
15 
16         if (StringUtils.isNotEmpty(status)){
17             orderQueryWrapper.eq("status",status);
18         }
19         if (StringUtils.isNotEmpty(serviceType)){
20             orderQueryWrapper.eq("service_type",serviceType);
21         }
22         if (StringUtils.isNotEmpty(createTimeBegin) && StringUtils.isNotEmpty(createTimeEnd)){
23             orderQueryWrapper.between("create_time",createTimeBegin,createTimeEnd);
24         }
25         //搜索条件: 患者姓名,手机号,下单人员 patient patient_phone user_name
26         String search = orderListVo.getSearch();
27         if (StringUtils.isNotEmpty(search)){
28             orderQueryWrapper.and(wrapper->wrapper.like("patient",search))
29                     .or()
30                     .like("patient_phone",search)
31                     .or()
32                     .like("user_name",search);
33         }
34         orderQueryWrapper.orderByDesc("update_time");
35         //查询
36         Page<Order> page = this.page(orderPage, orderQueryWrapper);
37         List<Order> orderList = page.getRecords();
38         //给返回值赋值
39         ArrayList<OrderInfoDto> orderInfoDtos = new ArrayList<>();
40         orderList.forEach(order -> {
41             OrderInfoDto orderInfoDto = new OrderInfoDto();
42             BeanUtils.copyProperties(order,orderInfoDto);
43             orderInfoDtos.add(orderInfoDto);
44         });
45 
46         result.setOrderInfoDtoList(orderInfoDtos);
47         result.setPageIndex(orderListVo.getPageIndex());
48         result.setPageSize(orderListVo.getPageSize());
49         result.setPageNum(page.getPages());
50         result.setTotal(page.getTotal());
51         /**
52          * 总计的字段
53          */
54         TotalNumber totalNumber = new TotalNumber();
55         List<Order> allOrders = this.list();
56         //下单数(去除已取消订单)
57         Integer size = allOrders.stream().filter(order -> !order.getStatus().equals(OrderStatusConstant.YQX)).collect(Collectors.toList()).size();
58         totalNumber.setOrderNum(size);
59         //完成订单数(所有已完成)
60         int finished = allOrders.stream().filter(order -> order.getStatus().equals(OrderStatusConstant.YWC)).collect(Collectors.toList()).size();
61         totalNumber.setFinishNum(finished);
62         //应收金额(去除已取消,已退款订单)
63         allOrders.removeIf(order -> order.getStatus().equals(OrderStatusConstant.YQX) || order.getStatus().equals(OrderStatusConstant.YTK));
64         BigDecimal amountSum = allOrders.stream().map(Order::getAmount).reduce(BigDecimal::add).get();
65         totalNumber.setTotalAmount(amountSum);
66         result.setTotalNumber(totalNumber);
67 
68         return result;
69     }

like查询匹配多个字段的写法:
 //搜索条件: 患者姓名,手机号,下单人员 patient patient_phone user_name
        String search = orderListVo.getSearch();
        if (StringUtils.isNotEmpty(search)){
            orderQueryWrapper.and(wrapper->wrapper.like("patient",search))
                    .or()
                    .like("patient_phone",search)
                    .or()
                    .like("user_name",search);
        }

sql语句为:

SELECT 
id,desire_hospital,desire_dept,desire_time,patient,identity_num,
patient_phone,identity_img,sick_desc,medical_record,insurance_img,amount,
account_id,user_name,account_num,status,pay_time,create_time,update_time,deleted,
final_hospital,final_dept,final_time,doctor,service_type
FROM `order`
WHERE deleted=0 AND ((patient LIKE ?) OR patient_phone LIKE ? OR user_name LIKE ?) ORDER BY update_time DESC LIMIT ?

==> Parameters: %王武%(String), %王武%(String), %王武%(String), 10(Long)
