Question

我有一个YAML文件，如下所示：

---
name:
  storage:
    documentfiles:
      username: rafa
      password: hello

我正在尝试获取最后两个username和password值。我目前的代码如下。我正在使用Map来存储YAML值，但由于当map.get()任何超过name的内容时有多个子项，因此它会给我一个空值。如果我map.get(name)我得到{storage={documentfiles={username=rafa, password=hello}}}有谁知道我如何才能正确获取用户名和密码？

public Map grabYaml(){
    Yaml reader = new Yaml();

    InputStream inputStream = getClass().getClassLoader().getResourceAsStream(yamlFileName);
    Map map = (Map) reader.load(inputStream);

    return map;
}

像这样的东西

public class Test {

    public Map grabYaml() throws IOException {
        Yaml reader = new Yaml();

        InputStream inputStream = new FileInputStream(new File(yamlFileName));
        Map map = (Map) reader.load(inputStream);

        return map;
    }

    public static void main(String[] args) throws IOException {
        Map storage = (Map) new Test().grabYaml().get("name");
        Map documentfiles = (Map)storage.get("storage");
        Map userData = (Map) documentfiles.get("documentfiles");

        System.out.println(userData.get("username"));
        System.out.println(userData.get("password"));
    }
}

YAML值无法正确返回
