简介

本算法为等级与时间结合计算对应优先级逻辑

等级越高者优先级越高
同等级下，时间越小者优先级越高

实现

主方法

calculatePriority

import com.zk.blog.enums.TypeEnum;
import org.apache.commons.lang3.StringUtils;/*** @program: * @description:* @author: zk* @create: 2024-08-09 17:26**/
public class PriorityService {/*** 基线时间* 2024-01-01 00:00:00* 秒值*/private static final Long baseTime = 1704067200L;/*** 前缀*/private static final String prefix = "1";/*** 按照阶梯类型+时间计算优先级* 类型级别越高、时间越前者优先级越高** @param type 类型 类型优先级最大2位* @param time 计算时间* @return 优先级结果 ：越大优先级越高*/public String calculatePriority(TypeEnum type, Long time) {//毫秒转秒if (String.valueOf(time).length() == 13) {time = time / 1000;}if (String.valueOf(time).length() != 10) {throw new RuntimeException("时间格式错误");}String typePriority = String.valueOf(type.getLevelPriority());String timePriority = String.valueOf(Integer.MAX_VALUE - (time - baseTime));typePriority = StringUtils.leftPad(typePriority, 2, "0");timePriority = StringUtils.leftPad(timePriority, 12, "0");return new StringBuilder().append(prefix).append(typePriority).append(timePriority).toString();}
}

采用：Integer.MAX_VALUE - (time - 基线时间)计算出时间优先级
等级优先级为2位，不够则左侧补0
时间优先级为12位，不够则左侧补0
最终优先级：:1位前缀+2位级别优先级+12位时间优先级 = 13位字符串

等级类型枚举

TypeEnum

/*** @program: * @description: 类型级别* @author: zk* @create: 2024-08-09 17:30**/
public enum TypeEnum {/*** 级别：描述, 等级优先级*/ONE("一级", 1),TWO("二级", 2),THREE("三级", 3),FOUR("四级", 4),FIVE("五级", 5),SIX("六级", 6),SEVEN("七级", 7),EIGHT("八级", 8),NINE("九级", 9),TEN("十级", 10);private String name;private Integer levelPriority;TypeEnum(String name, Integer levelPriority) {this.name = name;this.levelPriority = levelPriority;}public String getName() {return name;}public void setName(String name) {this.name = name;}public Integer getLevelPriority() {return levelPriority;}public void setLevelPriority(Integer levelPriority) {this.levelPriority = levelPriority;}
}
