营业额统计

重点:已完成订单金额要排除其他状态的金额 根据时间选择区间

设计vo用于后端向前端传输数据,dto用于后端接收前端发送的数据
java
@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));
}
java
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
//把每天的东西一个一个放进去
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 = 5
Map 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, ","))//使用字符串拼接工具
//将几个不同的时间字符串用逗号分隔开,组合成一个字符串
.turnoverList(StringUtils.join(turnoverList, ","))
.build();
