Creating GSON Object

问题:

How do I create a json Object using Google Gson? The following code creates a json object which looks like {"name":"john"}

JsonObject jsonObject = new JsonObject();
jsonObject.addProperty("name", "john");

How do I create a jSon Object like this one?

{"publisher":{"name":"john"}}

回答1:

JsonObject innerObject = new JsonObject();
innerObject.addProperty("name", "john");

JsonObject jsonObject = new JsonObject();
jsonObject.add("publisher", innerObject);

Just an FYI: Gson is really made for converting Java objects to/from JSON. If this is the main way you're using Gson, I think you're missing the point.

回答2:

Figured it out how to do it correctly using Java Objects.

Creator creator = new Creator("John");
new Gson().toJson(creator);

Implementation of Creator java class.

public class Creator {

    protected String name;

    protected HashMap<String, String> publisher = new HashMap<String, String>();

    public Creator(String name){
            publisher.put("name", name);
    }
}
