Two services registered with eureka, using feign call each other, with zuul as a gateway

The purpose of this demo is to use have two services able to call each other without hard-coding their location in code.

To do this:

• Create a Eureka server
• Create first service, register with eureka
• Create second service, register with eureka
• Create a feign client in first service, to call second service
• Create a feign client in second service, to call first service
• (Optional) Create a zuul gateway, so the brower/client only calls one host

This is a multiproject... project
eurekaserver - Eureka server demo
eurekafeign-firstservice - First service demo
eurekafeign-gateway - Zuul gateway demo
eurekafeign-secondservice - Second service demo

Open each project, run the project, go to the following urls to test:
http://localhost:8761/ -- See eureka with all of the instances running
http://localhost:8765/api/firstservice/querySecondService?name=John -- Using the feign client in first service to call second service
http://localhost:8765/api/secondservice/queryFirstService?name=John -- Using the feign client in second service to call first service
