需要对list集合中的description字段进行排序，description是汉字且包含汉字数字，如下：
new LegLists("来源-西宁", "第三百一十四赛段"),
new LegLists("平安-来源", "第一千三百一十四赛段"),
new LegLists("平安-西宁", "第六十三赛段")
根据第二个字段，第几赛段进行排序。
整体代码：
public static void main(String[] args) {List<LegLists> legLists = Arrays.asList(new LegLists("来源-西宁", "第三百一十四赛段"),new LegLists("平安-来源", "第一千三百一十四赛段"),new LegLists("平安-西宁", "第六十三赛段"));Collections.sort(legLists, new Comparator<LegLists>() {@Overridepublic int compare(LegLists o1, LegLists o2) {int num1 = extractNumber(o1.getDescription());int num2 = extractNumber(o2.getDescription());return Integer.compare(num1, num2);}private int extractNumber(String s) {Matcher matcher = Pattern.compile("[零一二三四五六七八九十百千万]+").matcher(s);if (matcher.find()) {return chineseNumberToInt(matcher.group());}return 0;}private int chineseNumberToInt(String chineseNumber) {Map<Character, Integer> chineseToArabic = new HashMap<>();chineseToArabic.put('零', 0);chineseToArabic.put('一', 1);chineseToArabic.put('二', 2);chineseToArabic.put('三', 3);chineseToArabic.put('四', 4);chineseToArabic.put('五', 5);chineseToArabic.put('六', 6);chineseToArabic.put('七', 7);chineseToArabic.put('八', 8);chineseToArabic.put('九', 9);chineseToArabic.put('十', 10);chineseToArabic.put('百', 100);chineseToArabic.put('千', 1000);chineseToArabic.put('万', 10000);int result = 0;int temp = 0;int lastUnit = 1;for (char ch : chineseNumber.toCharArray()) {int num = chineseToArabic.getOrDefault(ch, -1);if (num != -1) {if (num >= 10) { // it's a unit like 十，百，千，万if (temp == 0) {temp = 1;}result += temp * num;temp = 0;lastUnit = num;} else {temp = temp * 10 + num;}}}result += temp * lastUnit;return result;}});for (LegLists lists : legLists) {System.out.println(lists);}}static class LegLists {/*** 赛段名称*/private String legName;public LegLists(String legName, String description) {this.legName = legName;this.description = description;}/*** 对应的是第几赛段（截图文字描述用）*/private String description;public String getLegName() {return legName;}public void setLegName(String legName) {this.legName = legName;}public String getDescription() {return description;}public void setDescription(String description) {this.description = description;}@Overridepublic String toString() {return "LegLists{" +"legName='" + legName + '\'' +", description='" + description + '\'' +'}';}}下面是我抽出来的工具类，用于提取汉字中的中文数字，并转成数字：
public class ChineseNumber {public static int extractNumber(String s) {Matcher matcher = Pattern.compile("[零一二三四五六七八九十百千万]+").matcher(s);if (matcher.find()) {return chineseNumberToInt(matcher.group());}return 0;}public static int chineseNumberToInt(String chineseNumber) {Map<Character, Integer> chineseToArabic = new HashMap<>();chineseToArabic.put('零', 0);chineseToArabic.put('一', 1);chineseToArabic.put('二', 2);chineseToArabic.put('三', 3);chineseToArabic.put('四', 4);chineseToArabic.put('五', 5);chineseToArabic.put('六', 6);chineseToArabic.put('七', 7);chineseToArabic.put('八', 8);chineseToArabic.put('九', 9);chineseToArabic.put('十', 10);chineseToArabic.put('百', 100);chineseToArabic.put('千', 1000);chineseToArabic.put('万', 10000);int result = 0;int temp = 0;int lastUnit = 1;for (char ch : chineseNumber.toCharArray()) {int num = chineseToArabic.getOrDefault(ch, -1);if (num != -1) {if (num >= 10) { // it's a unit like 十，百，千，万if (temp == 0) {temp = 1;}result += temp * num;temp = 0;lastUnit = num;} else {temp = temp * 10 + num;}}}result += temp * lastUnit;return result;}
}剩下的排序就简单了
