service
调用接口推送数据

@Service@Slf4jpublicclassOverdueRecordServiceImplextendsServiceImpl<OverdueRecordMapper,OverdueRecord>implementsIOverdueRecordService{@ResourceprivateOverdueRecordMapperoverdueRecordMapper;@OverridepublicList<OverdueRecord>overDueSeven(){// 更新逾期天数overdueRecordMapper.updateDueDate();List<OverdueSevenRecord>overdueSevenRecords=overdueRecordMapper.overdueSeven();List<OverdueRecord>overdueRecords=overdueSevenRecords.stream().map(e->{OverdueRecordoverdueRecord=newOverdueRecord();BeanUtil.copyProperties(e,overdueRecord,false);returnoverdueRecord;}).collect(Collectors.toList());intsuccessCount=0;intfailCount=0;for(OverdueRecordoverdueRecord:overdueRecords){//try{// 发送提醒booleansent=this.sendReminder(overdueRecord,7);if(sent){// 标记已发送overdueRecord.setRemindedSevenDays(true);overdueRecordMapper.updateById(overdueRecord);successCount++;log.info("成功发送7天提醒，业务编号：{}",overdueRecord.getBusinessNo());}else{failCount++;log.warn("发送7天提醒失败，业务编号：{}",overdueRecord.getBusinessNo());}}catch(Exceptione){failCount++;log.error("发送7天提醒异常，业务编号：{}，错误：{}",overdueRecord.getBusinessNo(),e.getMessage(),e);}}returnnull;}privatebooleansendReminder(OverdueRecordoverdueRecord,intdays){//returntrue;}}

上门面仅展示了逾期7天的,逾期15、30的也是一样的，根据数据库字段查数据，然后调用推送接口，要自动发送用@XxlJob(“xxx”)即可

逾期15的sql是

DATEDIFF(CURDATE(),due_date)>=15ANDDATEDIFF(CURDATE(),due_date)<30

逾期30的sql是

DATEDIFF(CURDATE(),due_date)>=30
