如何使用snakeyaml获取yaml文件中的所有子项(及其子项)

import org.yaml.snakeyaml.Yaml;

import java.util.Map;
import java.util.List;
import java.io.InputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;

public class YamlParser {
    public static void main(String[] args) {
        Yaml yaml = new Yaml();
        try {
            InputStream inputStream = new FileInputStream("path/to/your/yaml/file.yaml");
            Map<String, Object> obj = yaml.load(inputStream);
            printMap("", obj);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }

    private static void printMap(String prefix, Map<String, Object> map) {
        for (Map.Entry<String, Object> entry : map.entrySet()) {
            String key = prefix.isEmpty() ? entry.getKey() : prefix + "." + entry.getKey();
            Object value = entry.getValue();
            if (value instanceof Map) {
                printMap(key, (Map<String, Object>) value);
            } else if (value instanceof List) {
                printList(key, (List<Object>) value);
            } else {
                System.out.println(key + ": " + value);
            }
        }
    }

    private static void printList(String prefix, List<Object> list) {
        for (int i = 0; i < list.size(); i++) {
            String key = prefix + "[" + i + "]";
            Object value = list.get(i);
            if (value instanceof Map) {
                printMap(key, (Map<String, Object>) value);
            } else if (value instanceof List) {
                printList(key, (List<Object>) value);
            } else {
                System.out.println(key + ": " + value);
            }
        }
    }
}
