responseentity, String to json

return type 이 ResponseEntity 일때

<200 OK,{id=11111, senderId=trusted-server, brandId=MYBRAND, type=TEMPLATE, senderIp=192.168.0.1, templateId=1017, players=[{id=1270218, playerId=newplayer, brandId= MYBRAND, isRead=null, messageId=11111}], messageParams=[{id=745210, name=nickname, value=class, messageId=11111}, {id=745211, name=BonusAmount, value=1, messageId=11111}]},{X-Content-Type-Options=[nosniff], X-XSS-Protection=[1; mode=block], Cache-Control=[no-cache, no-store, max-age=0, must-revalidate], Pragma=[no-cache], Expires=[0], X-Application-Context=[Hermes:swagger,dev:8080], Content-Type=[application/json;charset=UTF-8], Transfer-Encoding=[chunked], Date=[Thu, 22 Nov 2018 17:27:06 GMT]}>

이런식으로 리턴된다. 이걸 Json 형식으로 바꾸려면,

Object responseEntity = messageService.sendMessageRelease(new Long(3));
ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
String json = ow.writeValueAsString(responseEntity);

JsonNode resultObjectList = bpJsonHttpMessageConverter.getObjectMapper().readTree(json);

이때 json 값을 확인해 보면,

{

  "headers" : {

    "X-Content-Type-Options" : [ "nosniff" ],

    "X-XSS-Protection" : [ "1; mode=block" ],

    "Cache-Control" : [ "no-cache, no-store, max-age=0, must-revalidate" ],

    "Pragma" : [ "no-cache" ],

    "Expires" : [ "0" ],

    "X-Application-Context" : [ "Hermes:swagger,dev:8080" ],

    "Content-Type" : [ "application/json;charset=UTF-8" ],

    "Transfer-Encoding" : [ "chunked" ],

    "Date" : [ "Thu, 22 Nov 2018 17:27:06 GMT" ]

  },

  "body" : {

    "id" : 11111,

    "senderId" : "trusted-server",

    "brandId" : "MYBRAND",

    "type" : "TEMPLATE",

    "senderIp" : "192.168.0.1",

    "templateId" : 1017,

    "players" : [ {

      "id" : 1270218,

      "playerId" : "newplayer",

      "brandId" : "MYBRAND",

      "isRead" : null,

      "messageId" : 11111


    } ],

    "messageParams" : [ {

      "id" : 745210,

      "name" : "nickname",

      "value" : "class",

      "messageId" : 11111


    }, {

      "id" : 745211,

      "name" : "BonusAmount",

      "value" : 1,

      "messageId" : 11111

    } ]

  },

  "statusCode" : "OK",

  "statusCodeValue" : 200


}

좋군.
