java - 如何在snakeyaml中隐藏bean类型

Question

此代码将输出：（YAML）

--- !!org.test.bean.Person

地址：4011 16th Ave S

......

无论如何都可以隐藏我的bean类型（org.test.bean.Person）！？（更喜欢使用snakeyaml 配置...我找不到它..）

谢谢！！

public static void dumpYAML(){
    Constructor constructor = new Constructor(Person.class);
    TypeDescription personDescription = new TypeDescription(Person.class);
    personDescription.putListPropertyType("phone", Tel.class);
    constructor.addTypeDescription(personDescription);

    Yaml yaml = new Yaml(constructor);
    Person person = (Person) yaml.load(makeYAML());

    DumperOptions options = new DumperOptions();
    options.setDefaultFlowStyle(DumperOptions.FlowStyle.BLOCK);
    options.setCanonical(false); // display bean member attribute
    options.setExplicitStart(true); // display --- start

    yaml = new Yaml(options);
    String output = yaml.dump(person);
    System.out.println(output);
}

Answer 1

使用org.yaml.snakeyaml.representer.Representer, 设置Tag.MAP隐藏根标签。

Representer representer = new Representer();
representer.addClassTag(Person.class, Tag.MAP);

Answer 2

您可以将 Representer 扩展为“偷偷地”注入任何未注册的 bean 类作为 Map。

public class MapRepresenter extends Representer {

    @Override
    protected MappingNode representJavaBean(Set<Property> properties, Object javaBean) {
        if (!classTags.containsKey(javaBean.getClass()))
            addClassTag(javaBean.getClass(), Tag.MAP);

        return super.representJavaBean(properties, javaBean);
    }

}
