How to Disable Ribbon and just use FeignClient in Spring Cloud

Question

I am aware that we can force FeignClient to use OkHttp instead of Ribbon by providing the url Ex. @FeignClient(url="serviceId", name="serviceId")

I want the OkHttpClient to be used even when just the name is provided. Ex. @FeignClient(name="serviceId")

As per the spring cloud documentation "if Ribbon is enabled it is a LoadBalancerFeignClient, otherwise the default feign client is used."

How can I disable ribbon so that the default feign client will be used.

I had the same question but my setup is a bit different and I did not get it working in my case (using spring-cloud-starter-openfeign with spring mvc style annotations).

FYI: I needed a custom client with an SSLSocketFactory and ended up just creating the bean for the client and keeping the url on @FeignClient

 @Bean
 public Client myClient() {
     return new Client.Default(getSSLSocketFactory(), new NoopHostnameVerifier());
 }

However, we do have projects using spring-cloud-starter-feign where the URL is not provided on the annotation. Not sure if the config below is complete (I did not set it up) but it might point you in the right direction...

dependencies

compile("org.springframework.cloud:spring-cloud-starter-feign") {
    exclude group: 'org.springframework.cloud', module: 'spring-cloud-starter-ribbon'
    exclude group: 'org.springframework.cloud', module: 'spring-cloud-starter-archaius'
}

config

@Configuration
@Import(FeignClientsConfiguration.class) // org.springframework.cloud.netflix.feign.FeignClientsConfiguration
public class MyConfig {

    @Value("${client.url}")
    private String url;    

    @Bean
    public MyClient myClient(final Decoder decoder, final Encoder encoder, final Client client) {
        return Feign.builder().client(client)
            .encoder(encoder)
            .decoder(decoder)
            .target(MyClient.class, url);
    }
}
