How serialize an object as a value to ObjectNode in Jackson?

Question

I'm using jackson to serialize my object as json. I'm using following code:

ObjectMapper mapper = new ObjectMapper();
JsonNodeFactory nodeFactory = new JsonNodeFactory(false);
ObjectNode resNode = new ObjectNode(nodeFactory);

SimpleModule simpleModule = new SimpleModule();
simpleModule.addSerializer(ApplicationVersion.class, new SingleApplicationSerializer());
mapper.registerModule(simpleModule);
JsonNode appObject = mapper.valueToTree(appVersion);

resNode.put("status", true);
resNode.put("appObject", appObject);     //This put method is deprecated.

But I saw the put method with JsonNode overload is deprecated.Why following overload of put method is deprecated:

public JsonNode put(String fieldName, JsonNode value);

What is the alternative for that?

Also I tried this:

String jsonStr = mapper.writeValueAsString(appVersion);
resNode.put("status", true);
resNode.put("appObject", jsonStr);

But this method puts double quote (") around appObject value as a string value.

They added a new method for these actions. ObjectNode.put(String, JsonNode)

Try instead resNode.set("appObject", appObject);.
