[JSON] Build Nested ObjectNode

다음과 같이 object가 중첩된 json을 만들어 보자.

{
    "employee": {
        "company": "MyCom",
        "teams": {
            "team1": {
                "name": "AAAA",
                "location": "sector-a"
            },
            "team2": {
                "name": "BBBB",
                "location": "sector-b"
            }
        }
    }
}

Jackson 코드는 아래와 같다.

ObjectMapper mapper = new ObjectMapper();
ObjectNode root = mapper.createObjectNode();

ObjectNode employee = root.putObject("employee");

emplyee.put("compayn", "MyCom");

ObjectNode teams = employee.putObject("teams");

ObjectNode team1 = teams.putObject("team1");
team1.put("name", "AAAA");
team1.put("location", "sector-a");

ObjectNode team2 = teams.putObject("team2");
team2.put("name", "BBBB");
team2.put("location", "sector-b");
