@Configuration
public class RestTemplateConfig {

  @Bean
  public RestTemplate restTemplate() {
    RestTemplate restTemplate = new RestTemplate(new BufferingClientHttpRequestFactory(new
        SimpleClientHttpRequestFactory()));

    restTemplate.setInterceptors(Collections.singletonList(new RestTemplateFilter()));
    return restTemplate;
  }
}

Açıklaması şöyle

If we don’t initialise Rest Template with the BufferingClientHttpRequestFactory class, we will get an OK response to our requests but we will get a null value for the response body.

Açıklaması şöyle

In intercept method, the HTTP request is logged, including the HTTP method, URI and request body (if any), as well as the HTTP response, including status code, status text and response body (if any).
