如何使用snakeyaml获取yaml文件中的所有子级（及其子级）

Question

所以我和蛇怪打过交道。我知道如何使用java yaml.load(inputStream)获取它们的密钥；返回字符串和对象的hashmap。为了演示，我有一个包含值的yaml文件：

player:
  randie:
    score: 4

当我使用

File file = new File("test")
FileInputStream stream = new FileInputStream(file);

Map<String, Object> map = yaml.load(stream);

for (String str : map.keySet()) {
   System.out.println(map.get(str));
}

{randie={score=4}}

Answer 1

public class Result {
    private Player player;

    public Player getPlayer() {
        return player;
    }

    public void setPlayer(Player player) {
        this.player = player;
    } 
}

public class Player {
    private Randie randie;

    public Randie getRandie() {
        return randie;
    }

    public void setRandie(Randie randie) {
        this.randie = randie;
    } 
}

public class Randie {
    private int score;

    public int getScore() {
        return score;
    }

    public void setScore(int score) {
        this.score = score;
    } 
}

public class YamlDataInterpreter {

    public static void main(String[] args) {
        YamlDataInterpreter intepreter = new YamlDataInterpreter();
        intepreter.interpretYaml();
    }

    public void interpretYaml() {
        InputStream stream = this.getClass().getClassLoader()
            .getResourceAsStream("data.yml");

        Yaml yaml = new Yaml();
        Result res = yaml.loadAs(stream, Result.class);
        System.out.println(res.getPlayer().getRandie().getScore());
    }
}
