How can we send get request with data-urlencode body using RestTemplate Spring Boot

Question

Requirement is to send notification with auth token. And to get token we have been provided below curl command. I need to implement curl equivalent code to get the token so that I can use that token while sending the notification. I have implemented but it is not working whereas curl command is working fine. Please check below curl command and implemented code.

**CURL Command **

curl --location --request GET 'https://test.appleexpress.com/orderservicesapi/token' --header 'Content-Type: application/x-www-form-urlencoded' --header 'Cookie: visid_incap_2670687=PgVnXOJwTveM+f+unLbHivuZr2QAAAAAQUIPAAAAAAAGR2Wbz5NgMv8yRX/u7VZP' --data-urlencode 'username=3062:HONGKONGWISE' --data-urlencode 'password=mjtwj2v7YfsUstu' --data-urlencode 'grant_type=password'

**Implemented Code **

public void getToken() throws UnsupportedEncodingException {

        String username = "3062:HONGKONGWISE";
        String password = "mjtwj2v7YfsUstu";
        String grantType = "password";
        String params = "username=" + URLEncoder.encode(username, "UTF-8") +
                "&password=" + URLEncoder.encode(password, "UTF-8") +
                "&grant_type=" + URLEncoder.encode(grantType, "UTF-8");

        ResponseEntity<String> responseEntity = null;
        RestTemplate restTemplate = utils.getClientTimeOutInRestTemplate();
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
        headers.set("Cookie", "visid_incap_2670687=PgVnXOJwTveM+f+unLbHivuZr2QAAAAAQUIPAAAAAAAGR2Wbz5NgMv8yRX/u7VZP");
        HttpEntity<String> entity = new HttpEntity<>(params,headers);


        try {
            log.info("RMS_SERVER : getToken : Authorization API : {}", authUrl);
            log.info("RMS_SERVER : getToken : Sendind Request to authorization API : {}", entity);

            responseEntity = restTemplate.exchange(authUrl, HttpMethod.GET, entity, String.class);

            if (responseEntity.getStatusCode().is2xxSuccessful() && null != responseEntity.getBody()) {
                log.info("RMS_SERVER : getToken : Response of authorization API is: {}", responseEntity.getBody());
                String authRequest = responseEntity.getBody();
                JSONObject jsonAuthRequest = new JSONObject(authRequest);
                this.setAuthtoken(jsonAuthRequest.getString(ACCESS_TOKEN));
                log.info("RMS_SERVER : getToken : Token successfully received ");
            } else {
                log.error("RMS_SERVER : getToken : Token not received ");
            }
        } catch (HttpStatusCodeException e) {
            log.error(String.format("RMS_SERVER : getToken : HttpStatusCodeException Occurred Caused By: %s : Status Code : %s ", e.getResponseBodyAsString(), e.getStatusCode()));
            throw new AppException(e.getResponseBodyAsString(), e.getStatusCode());
        } catch (ResourceAccessException e) {
            log.error(String.format("RMS_SERVER : getToken : ResourceAccessException Occurred Caused By: %s", e.getLocalizedMessage()));
            throw new AppException(e.getLocalizedMessage(), HttpStatus.INTERNAL_SERVER_ERROR);
        } catch (RestClientException e) {
            log.error("RMS_SERVER : getToken : Received exception while sending Request to authorization API: %s" + e.getLocalizedMessage());
            throw new AppException(e.getLocalizedMessage(), HttpStatus.INTERNAL_SERVER_ERROR);
        }
    }

I tried to implement the code but not succeeded getting below error. Auth API:- https://test.appleexpress.com/orderservicesapi/token
