import import org.springframework.web.client.RestTemplate;

public class CustomRestTemplateCustomizer implements RestTemplateCustomizer {

    @Override
    public void customize(RestTemplate restTemplate) {
        HttpHeaders headers = new HttpHeaders();
        headers.add("Custom-Header", "Custom-Value");
        restTemplate.setInterceptors(Collections.singletonList(new CustomHeaderInterceptor(headers)));
    }
}

}
