Using Ribbon load balancing in spring cloud and autowiring the annotated interface - spring

Question

We are new to spring-cloud and struck with Ribbon Client dependencies. The code is working fine with FeignClient but using RibbonClient annotations resulting in application start fail.please find the code below.

The Ribbon annotated interface.
import org.springframework.cloud.netflix.ribbon.RibbonClient;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
//#FeignClient(url="http://localhost:7000",name="customer") //works fine
#RibbonClient(name="customer") //Autowiring fails
public interface AccountFeign {
#GetMapping(value="/fetchcustomerdetails/{id}")
public Account fetchCustomerDetailsUsingFeign(#PathVariable("id") int id);
}
The Controller as follows.
#RestController
public class AccountResource {
#Autowired
AccountFeign accountFeign; //Fails with RibbonClient annotation
}
We are invoking web-service in another microservice which can be seen from the attributes of FeignClient and works fine but the Autowiring of the interface fails when used with the RibbonClient annotation. can someone help us understand please. Thanks in advance.
