내가 필요한건 result 값만 필요함.

@GetMapping("/api/coordinatesToAddress")
public ResponseEntity restTemplateTest(@RequestParam String point) {

    String url = "http://api.vworld.kr/req/address";
    UriComponents uri = UriComponentsBuilder.fromHttpUrl(url)
            .queryParam("service", "address")
            .queryParam("request", "getAddress")
            .queryParam("key", "key값")
            .queryParam("crs", "epsg:4326")
            .queryParam("point", point)
            .queryParam("type", "BOTH")
            .build();

    ResponseEntity<String> resultAPI = restTemplate.exchange(uri.toString(), HttpMethod.GET, null, String.class);

 	JSONParser parser = new JSONParser();
    JSONObject parse = (JSONObject) parser.parse(resultAPI.getBody());
    JSONObject response = (JSONObject) parse.get("response");
    JSONArray result = (JSONArray) response.get("result");
    JSONObject roadName = (JSONObject) result.get(0);
    JSONObject structure = (JSONObject) roadName.get("structure");
    String roadText = (String) roadName.get("text");

    ....
}
