• 소스 코드 : https://github.com/yewon-Noh/spring-cloud/tree/main/spring-cloud-nexflix

1) Eureka Server 설정

dependency 추가

<!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-netflix-eureka-server -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
    <version>4.1.0</version>
</dependency>

 

메인 클래스에 @EnableEurekaServer 어노테이션 추가하여 Eureka Server 임을 알려준다.

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerTestApplication {

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

}

 

기본 설정을 추가한다.

bootstrap.yml

spring:
  application:
    name: discovery-service

 

application.yaml

server:
  port: 8761
  
eureka:
  client:
    register-with-eureka: false
    fetch-registry: false

• eureka.client
  • register-with-eureka (default=true)
    • eureka server를 registry에 등록할지 여부
  • fetch-registry (default=true)
    • registry에 있는 정보들을 가져올지 여부

 

localhost:8761 에 들어가면 Eureka Dashboard를 볼 수 있다.

 

 

2) Eureka Client 설정

dependency 추가

<!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-netflix-eureka-client -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    <version>4.1.0</version>
</dependency>

 

메인 클래스에 @EnableDiscoveryClient 어노테이션을 추가하여 Eureka Client 임을 알려준다.

@SpringBootApplication
@EnableDiscoveryClient
public class EurekaClientTestApplication {

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

}

 

설정을 추가한다.

bootstrap.yml

spring:
  application:
    name: eureka-client-test

 

application.yaml 에 기본 설정을 해준다.

server:
  port: 8080

eureka:
  client:
    fetch-registry: true
    register-with-eureka: true
    service-url:
      defaultZone: <http://127.0.0.1:8761/eureka>

• eureka.client
  • service-url.defaultZone
    • eureka server를 명시한다.

 

Eureka Dashboard 에서 서비스가 등록된 것을 확인할 수 있다.
