org.springframework.beans.factory.UnsatisfiedDependencyException on Cloud Rest Client with Netflix Ribbon

I am getting a org.springframework.beans.factory.UnsatisfiedDependencyException while running SpringClientSideRibbonApplication.java class. I think there is no error but I don't know why this exception comes. Please help me. I am using STS IDE.

MyConfiguration.java

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import com.netflix.client.config.IClientConfig;
import com.netflix.loadbalancer.IPing;
import com.netflix.loadbalancer.IRule;
import com.netflix.loadbalancer.PingUrl;
import com.netflix.loadbalancer.WeightedResponseTimeRule;
public class MyConfiguration {
@Autowired
IClientConfig ribbonClientConfig;   
@Bean
public IPing ribbonPing(IClientConfig config) {
    return new PingUrl();
}

@Bean
public IRule ribbonRule() {
  return new WeightedResponseTimeRule();
}


}

SpringClientSideRibbonApplication.java

package com.javasampleapproach.ribbon;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.ribbon.RibbonClient;

@SpringBootApplication
@RibbonClient(name = "helloworld", configuration = 
MyConfiguration.class)
public class SpringClientSideRibbonApplication {

public static void main(String[] args)
{
    SpringApplication.run(SpringClientSideRibbonApplication.class, 
args);
}
}

WebController.java

package com.javasampleapproach.ribbon;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
@RestController
public class WebController {
@LoadBalanced
@Bean
RestTemplate restTemplate() {
    return new RestTemplate();
}
@Autowired
RestTemplate restTemplate;
@RequestMapping("/helloworld")
public String home() {      
    return  
this.restTemplate.getForObject("http://helloworld/greeting", 
String.class);
}
}
