一、背景在很多业务场景下，需要根据持续天数来计算分值的场景，依我现在线上的一个业务为例，来展开说明，我们的业务场景是一个预警分值计算，通过采集个人的健康数据来进行预警，每天都要计算体温、心率、血氧等指标看看是否异常，比如血氧连续持续两天异常，则打标 15 分

二、架构设计

三、java 实现

/**

@desc 得分项，一些指标指示位枚举类*/public enum IndicatorDataEnum {
/**
心率连续 7 天小于 50/HR_50(0),/*
血氧连续 7 天小于 50*/OXY_LESS_50(1),;
/**
二进制指示物位(bit 值) 如 7 二进制标识 0000 0000 0000 0111
即 0 ，1 ，2 指示位满足*/private final Integer num;
IndicatorDataEnum(Integer num) {this.num = num;}
public Integer getNum() {return num;}

}

public class YJCal {

public static Integer getIndicator() {    //从数据库读取数据    List<AlertScoreDTO> alertScoreDTOList = generateRandomData(10);
    int indicatorData = 0;    //1 心率异常 判定      2.2    indicatorData |= checkHrAbnormal(alertScoreDTOList)            ? 1 << IndicatorDataEnum.HR_50.getNum() : 0;    boolean bloodOxygenAbnormal = checkOxyAbnormal(alertScoreDTOList);    indicatorData |= bloodOxygenAbnormal ? 1 << IndicatorDataEnum.OXY_LESS_50.getNum() : 0;    return indicatorData;}
private static List<AlertScoreDTO> generateRandomData(int count) {    List<AlertScoreDTO> alertScoreDTOList = new ArrayList<>();    Random random = new Random();
    for (int i = 0; i < count; i++) {        Long id = (long) i + 1;        Integer hrScore = random.nextInt(101);  // 随机生成0到100之间的整数        Integer bloodOxygenScore = random.nextInt(101);  // 随机生成0到100之间的整数        Integer indicatorData = 3;
        AlertScoreDTO alertScoreDTO = new AlertScoreDTO(id, hrScore, bloodOxygenScore, indicatorData);        alertScoreDTOList.add(alertScoreDTO);    }
    return alertScoreDTOList;}
public static boolean checkHrAbnormal(List<AlertScoreDTO> alertScoreDTOList) {    int days = getConsecutiveCount(IndicatorDataEnum.HR_50, alertScoreDTOList);    if(days > 3) {        return true;    }    return false;}
public static boolean checkOxyAbnormal(List<AlertScoreDTO> alertScoreDTOList) {    //此处省略业务逻辑   return true;}
private static int getConsecutiveCount(IndicatorDataEnum dataEnum, List<AlertScoreDTO> alertScoreDTOList) {    int days = 0;    for (int i = 0; i < alertScoreDTOList.size(); i++) {        AlertScoreDTO alertScoreDTO = alertScoreDTOList.get(i);        if (((1 << dataEnum.getNum()) & alertScoreDTO.getIndicatorData()) == 0) {            //不连续了直接结束            break;        }        days++;    }    return days;}
public static void main(String[] args) {    System.out.println(getIndicator());}
