Force Jackson to add addional wrapping using annotations

I have the following class:

public class Message {
    private String text;

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }    
}

When converting the instance to JSON using Jackson by default I get:

{"text":"Text"}

I would like to get:

{"message":{"text":"Text"}}

Is there any JAXB / Jackson annotation I can use to achieve my goal?

As a workaround, I can wrap my class with another class:

public class MessageWrapper {
    private Message message;

    public Message getMessage() {
        return message;
    }

    public void setMessage(Message message) {
        this.message = message;
    }
}

or a more generic solution:

public class JsonObjectWrapper<T> {
    /**
     * Using a real map to allow wrapping multiple objects
     */
    private Map<String, T> wrappedObjects = new HashMap<String, T>();

    public JsonObjectWrapper() {
    }

    public JsonObjectWrapper(String name, T wrappedObject) {
        this.wrappedObjects.put(name, wrappedObject);
    }

    @JsonAnyGetter
    public Map<String, T> any() {
        return wrappedObjects;
    }

    @JsonAnySetter
    public void set(String name, T value) {
        wrappedObjects.put(name, value);
    }
}

Which can be used like so:

Message message = new Message();
message.setText("Text");
JsonObjectWrapper<Message> wrapper = new JsonObjectWrapper<Message>("message", message);

Is there any JAXB / Jackson annotation I can use to achieve my goal?

Thanks.
