Apache ECharts
前端技术。
营业额统计
还是比较简单的。
用户统计
订单统计
以上所有需求。难点在于对时间类的处理:
// 接收格式
@GetMapping("/turnoverStatistics")@ApiOperation("营业额统计")public Result<TurnoverReportVO> turnoverStatistics(@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate begin,@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate end){log.info("营业额统计:{},{}", begin, end);return Result.success(reportService.getTurnoverStatistics(begin, end));}
//日期扩展到时分秒
@Overridepublic TurnoverReportVO getTurnoverStatistics(LocalDate begin, LocalDate end) {// deteList: 开始日期,到结束日期List<LocalDate> dateList = new ArrayList<>();dateList.add(begin);while (!begin.equals(end)){begin = begin.plusDays(1);dateList.add(begin);}List<Double> turnoverList = new ArrayList<>();for (LocalDate date : dateList) {LocalDateTime dateBegin = LocalDateTime.of(date, LocalTime.MIN);LocalDateTime dateEnd = LocalDateTime.of(date, LocalTime.MAX);Map map = new HashMap();map.put("begin", dateBegin);map.put("end", dateEnd);map.put("status", Orders.COMPLETED);Double turnover = orderMapper.sumByMap(map);turnover = turnover == null ? 0.0 : turnover;turnoverList.add(turnover);}return TurnoverReportVO.builder().dateList(StringUtils.join(dateList, ",")).turnoverList(StringUtils.join(turnoverList, ",")).build();}
销量排名Top10
难点在于查询数据库设计。
order_detail一张表不够,还需要确定对应的订单是否是完成状态。——》连接查询
<select id="getSalesTop10" resultType="com.sky.dto.GoodsSalesDTO">select od.name name, sum(od.number) numberfrom order_detail od, orders owhere od.order_id = o.id and o.status=5<if test="begin != null">and order_time > #{begin}</if><if test="end != null">and order_time < #{end}</if>group by od.nameorder by number desclimit 0,10</select>
