This module includes a feign Target and Client adapter to take advantage of Ribbon.
This integration relies on the Feign Target.url() being encoded like https://myAppProd where myAppProd is the ribbon client or loadbalancer name and myAppProd.ribbon.listOfServers configuration is set.
Adding RibbonClient overrides URL resolution of Feign's client, adding smart routing and resiliency capabilities provided by Ribbon.

MyService api = Feign.builder().target(MyService.class, "https://myAppProd-1234567890.us-east-1.elb.amazonaws.com");do
MyService api = Feign.builder().client(new RibbonClient()).target(MyService.class, "https://myAppProd");Using or extending LoadBalancingTarget will enable dynamic url discovery via ribbon including incrementing server request counts.
