我如何使序列化器也打印原始报价？

而不是使用高级API。引用规范：

标量样式是一个表示细节，不得用于传达内容信息，但为了标记解析的目的区分普通标量除外。

final Yaml yaml = new Yaml();
final Iterator<Event> events = yaml.parse(new StreamReader(new UnicodeReader(
        new FileInputStream(new File("test.yml"))).iterator();

final DumperOptions yamlOptions = new DumperOptions();
final Emitter emitter = new Emitter(new PrintWriter(System.out), yamlOptions);
while (events.hasNext()) emitter.emit(events.next());
