public class MyConfiguration {
#Autowired
IClientConfig ribbonClientConfig;
#Bean
public IPing ribbonPing(IClientConfig config) {
return new PingUrl();
}
#Bean
public IRule ribbonRule() {
return new WeightedResponseTimeRule();
}
}

#RibbonClient(name = "helloworld", configuration =
MyConfiguration.class)
public class SpringClientSideRibbonApplication {
public static void main(String[] args)
{
SpringApplication.run(SpringClientSideRibbonApplication.class,
args);
}
}
