开始集成eureka，服务端

1. pom.xml中添加

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>

2. 启动类

@SpringBootApplication
@EnableEurekaServer
public class ChilliApplication {
    public static void main(String[] args) {
        SpringApplication.run(ChilliApplication.class, args);
    }
}

3. 配置文件

server:
  port: 55580

spring:
  application:
    name: asfood-chilli
  profiles:
    active: dev

eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

logging:
  file: ./logs/chilli.log

4. 客户端配置

添加同样的pom依赖；

配置文件中添加

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:55580/eureka/

启动类添加注释：@EnableEurekaClient

至于@EnableEurekaClient和@EnableDiscoveryClient的区别可以百度，建议的是，使用eureka就用EnableEurekaClient。

可以通过访问eureka客户端查看已经注册的服务。
