오늘의 코딩 포인트

1. eureka 클라우드 서버 만들어 배포

 

• build.gradle 확인

plugins {
	id 'java'
	id 'org.springframework.boot' version '3.3.3'
	id 'io.spring.dependency-management' version '1.1.6'
}

group = 'com.oracle'
version = 'version.1.0'

java {
	toolchain {
		languageVersion = JavaLanguageVersion.of(17)
	}
}

repositories {
	mavenCentral()
}

ext {
	set('springCloudVersion', "2023.0.3")
}

dependencies {
	implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-server'
	testImplementation 'org.springframework.boot:spring-boot-starter-test'
	testRuntimeOnly 'org.junit.platform:junit-platform-launcher'
}

dependencyManagement {
	imports {
		mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
	}
}

tasks.named('test') {
	useJUnitPlatform()
}

 

• OBootMsaDiscoveryServiceApplication

@SpringBootApplication
@EnableEurekaServer
public class OBootMsaDiscoveryServiceApplication {

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

}

 

• application.yml

server:
  port: 8761
  
spring:
  application:
    name: service-discovery
    
eureka:
  client:
    register-with-eureka: false 
    # 클라이언트가 eureka 서비스에 자신을 등록하지 않음
    fetch-registry: false 
    # 레지스트리 정보를 클라이언트 로컬에 캐싱하지 않음
    # eureka 클라이언트가 eureka 서비스에 등록시 설정 가능
