Ribbon

This module includes a feign Target and Client adapter to take advantage of Ribbon.

Conventions

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.

RibbonModule

Adding RibbonModule overrides URL resolution of Feign's client, adding smart routing and resiliency capabilities provided by Ribbon.

Usage

instead of 

MyService api = Feign.create(MyService.class, "https://myAppProd-1234567890.us-east-1.elb.amazonaws.com");

do

MyService api = Feign.create(MyService.class, "https://myAppProd", new RibbonModule());

LoadBalancingTarget

Using or extending LoadBalancingTarget will enable dynamic url discovery via ribbon including incrementing server request counts.

Usage

instead of

MyService api = Feign.create(MyService.class, "https://myAppProd-1234567890.us-east-1.elb.amazonaws.com");

do

MyService api = Feign.create(LoadBalancingTarget.create(MyService.class, "https://myAppProd"));
