We will use Spring Initializr (http://start.spring.io) to set up a new project for Zuul API Gateway. The following screenshot shows the GroupId, ArtifactId, and Dependencies to be selected:

The next step is to enable Zuul proxy on the Spring Boot application. This is done by adding the @EnableZuulProxy annotation on the ZuulApiGatewayServerApplication class. The following snippet shows the details:

    @EnableZuulProxy
    @EnableDiscoveryClient
    @SpringBootApplication
    public class ZuulApiGatewayServerApplication {

We will run Zuul Proxy on port 8765. The following snippet shows the configuration needed in application.properties:

    spring.application.name=zuul-api-gateway
    server.port=8765
    eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka

We are configuring the port for Zuul proxy and connecting it to the Eureka Name server as well.
