如何在一个 Spring Boot 应用程序中的不同端口上运行 api-gateway(Netflix Zuul) 和 Eureka Server

Question

I have a Spring Boot application which is EurekaServer as well as ZuulServer . My questions are:

• Is it possible to run both servers on different ports?
• If possible then, what should be the application configuration?

I have attached the configuration which I tried, but it's not giving me the desired output.

@SpringBootApplication
@EnableZuulProxy
@EnableEurekaServer
public class AppApiGatewayApplication {

    public static void main(String[] args) {
        SpringApplication.run(AppApiGatewayApplication.class, args);
    }

}

spring:
  application:
    name: gateway

server:
  port: 8001

eureka:
  instance:
   hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://localhost:9090/eureka/       

Answer 1

You can try like below

server:
  port: ${appPort:8880}
  additionalPorts: 8882,8883

# Spring MVC actuator endpoints available via /admin/info, /admin/health, ...
server.servlet-path: /
management:
  context-path: /admin
  port: 8881 

The best way to design microservice is to have separate EurekaServer and register your ZuulServer to Eureka. Please refer below link
