营业额统计

产品原型

接口设计

新建admin/ReportController 

/*** 数据统计相关接口*/
@RestController
@RequestMapping("/admin/report")
@Api(tags = "数据统计相关接口")
@Slf4j
public class ReportController {@Autowiredprivate ReportService reportService;/*** 营业额统计* @param begin* @param end* @return*/@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("营业额数据统计：{},{}",begin,end);return Result.success(reportService.getTurnoverStatistics(begin,end));}}

新建ReportService

public interface ReportService {/*** 统计指定时间区间内的营业额数据* @param begin* @param end* @return*/TurnoverReportVO getTurnoverStatistics(LocalDate begin,LocalDate end);
}

ReportServiceImpl

@Service
@Slf4j
public class ReportServiceImpl implements ReportService {@Autowiredprivate OrderMapper orderMapper;/*** 统计指定时间区间内的营业额数据* @param begin* @param end* @return*/public TurnoverReportVO getTurnoverStatistics(LocalDate begin, LocalDate end) {//当前集合用于存放从begin到end范围内的每天的日期List<LocalDate> dateList = new ArrayList<>();dateList.add(begin);while (!begin.equals(end)){//日期计算，计算指定日期的后一天对应的日期begin = begin.plusDays(1);dateList.add(begin);}//存放每天的营业额List<Double> turnoverList = new ArrayList<>();for (LocalDate date : dateList) {//查询date日期对应的营业额数据，营业额是指，状态为"已完成"的订单金额合计LocalDateTime beginTime = LocalDateTime.of(date, LocalTime.MIN);LocalDateTime endTime = LocalDateTime.of(date, LocalTime.MAX);//select sum(amount) from orders where order_time > beginTime and order_time < endTime and status = 5Map map = new HashMap();map.put("begin",beginTime);map.put("end",endTime);map.put("status", Orders.COMPLETED);Double turnover = orderMapper.sumByMap(map);turnover = turnover == null ? 0.0 : turnover;turnoverList.add(turnover);}//封装返回结果return TurnoverReportVO.builder().dateList(StringUtils.join(dateList,",")).turnoverList(StringUtils.join(turnoverList,",")).build();}
}

 OrderMapper

    /*** 根据动态条件统计营业额数据* @param map* @return*/Double sumByMap(Map map);

OrderMapper.xml

    <select id="sumByMap" resultType="java.lang.Double">select sum(amount) from orders<where><if test="begin != null">and order_time &gt; #{begin}</if><if test="end != null">and order_time &lt; #{end}</if><if test="status != null">and status = #{status}</if></where></select>
