json between object (codehaus.jackson)

지정한 depth 까지만 object 로 변환하고 나머지는 기존 json string 을 유지해야 할 경우

String test_obj = "{\"title\":\"타이틀\",\"location\":\"회의실\",\"contact\":[\"김과장\",\"이과장\",\"박과장\"]}";

System.out.println(test_obj);

ObjectMapper mapper = new ObjectMapper();

Map<String,Object> sample_map = new HashMap<String,Object>();

sample_map.put("test", "value");

sample_map = mapper.readValue(test_obj, new TypeReference<HashMap<String,JsonNode>>(){});

for(Entry<String, Object> entry : sample_map.entrySet()) {

String key = entry.getKey();

Object value = entry.getValue();

System.out.println(String.format("[key : %s] - [value : %s]", key,value));

}

{"title":"타이틀","location":"회의실","contact":["김과장","이과장","박과장"]}

[key : title] - [value : "타이틀"]

[key : location] - [value : "회의실"]

[key : contact] - [value : ["김과장","이과장","박과장"]]
