gateway with routing

@EnableZuulServer is used when you want to build your own routing service and not use any Zuul prebuilt capabilities. An example of this would be if you wanted to use Zuul to integrate with a service discovery engine other than Eureka (for example, Consul). We’ll only use the @EnableZuulServer annotation in this book.

The Zuul proxy server is designed by default to work on the Spring products. As such, Zuul will automatically use Eureka to look up services by their service IDs and then use Netflix Ribbon to do client-side load balancing of requests from within Zuul.
