@Configuration
public class AppConfig{
    @Bean
    public RestTemplate customRestTemplate(){

        (3000);
        (3000);
        (3000);

        return new RestTemplate(httpRequestFactory);

    public HttpComponentsClientHttpRequestFactory customHttpRequestFactory() {
        return new HttpComponentsClientHttpRequestFactory();

    @Bean
    public RestTemplate customRestTemplate(){
        return new RestTemplate(customHttpRequestFactory());
    }
}

    {
        return restTemplateBuilder
