코틀린 json parsing with jackson

https://github.com/FasterXML/jackson-module-kotlin

1. app level build.gradle 파일내 dependencies 안에 compile "com.fasterxml.jackson.module:jackson-module-kotlin:2.8.7" 추가 (버전은 변경될 수 있음)
2. jackson instance
    val mapper = jacksonObjectMapper()

3. json 데이터 예제
{
    "name": "DEMO",
    "version": 0,
    "server": {
        "url": "http://sarangnamu.net",
        "path": "/path"
    },
    "serverMap": {
        "map1": {
            "url": "http://map1.sarangnamu.net",
            "path": "/path"
        }
    }
}

4. data class 작성
data class Server(
    val name: String,
    val version: Int,
    val server: ServerInfo
    val serverMap: Map<String, ServerInfo>
)

data class ServerInfo(
    val url: String,
    val path: String
)

5. 파싱
val mapper = jacksonObjectMapper()
val serverInfo = mapper.readValue<Server>(jsonString)
val serverInfoString = mapper.writeValueAsString(serverInfo)

끝.
