RestTemplate

| import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.web.client.RestTemplate;
...
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
String jsonData = "{\"field1\":\"value1\",\"field2\":\"value2\"}";
HttpEntity<String> entity = new HttpEntity<>(jsonData, headers);
String url = "http://example.com/api/v1/resource";
String result = restTemplate.postForObject(url, entity, String.class);
