무중단 배포 구현하기 - (3)

스프링부트(Springboot) 프로젝트 설정
HealthCheck 컨트롤러 생성
application.yml 세팅

[7] 스프링부트(Springboot) 프로젝트 설정

스프링부트 gradle로 프로젝트 생성 및 진행한다
buid.gradle > 아래 코드 추가(build 시 plain 스냅샷 생성 방지 위함)

jar {
	enabled = false
}

build.gradle의 dependencies 설정

  
dependencies {
	implementation 'javax.xml.bind:jaxb-api:2.3.1'
	implementation 'org.springframework.cloud:spring-cloud-starter-aws:2.2.6.RELEASE'

	//validation
	implementation 'org.springframework.boot:spring-boot-starter-validation'


	// JWT
	compileOnly group: 'io.jsonwebtoken', name: 'jjwt-api', version: '0.11.5'
	runtimeOnly group: 'io.jsonwebtoken', name: 'jjwt-impl', version: '0.11.5'
	runtimeOnly group: 'io.jsonwebtoken', name: 'jjwt-jackson', version: '0.11.5'


	// Security
	implementation 'org.springframework.boot:spring-boot-starter-security'

	runtimeOnly 'com.h2database:h2'
	implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
	implementation 'org.springframework.boot:spring-boot-starter-validation'
	implementation 'org.springframework.boot:spring-boot-starter-web'
	compileOnly 'org.projectlombok:lombok'
	developmentOnly 'org.springframework.boot:spring-boot-devtools'
	annotationProcessor 'org.projectlombok:lombok'
	testImplementation 'org.springframework.boot:spring-boot-starter-test'

	implementation 'mysql:mysql-connector-java:8.0.27'

[8] HealthCheck 컨트롤러 생성

그린서버나 블루 서버가 실행될 때 잘 돌아가고 있는지 아래와 같이 확인 용도로 사용한다
green 서버 실행시
blue 서버 실행시
HealthCheckController 파일

  
package com.sparta.eroomprojectbe.domain.member.controller;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.Map;
import java.util.TreeMap;
@RestController
public class HealthCheckController {
    @Value("${server.env}")
    private String env;
    @Value("${server.port}")
    private String serverPort;
    @Value("${server.serverAddress}")
    private String serverAddress;
    @Value("${serverName}")
    private String serverName;
    @GetMapping("/health")
    public ResponseEntity<?> healthCheck() {
        Map<String, String> responseData = new TreeMap<>();
        responseData.put("serverName", serverName);
        responseData.put("serverPort", serverPort);
        responseData.put("serverAddress", serverAddress);
        responseData.put("env", env);
        return ResponseEntity.ok(responseData);
    }
    @GetMapping("/env")
    public ResponseEntity<?> getEnv() {
        return ResponseEntity.ok(env);
    }
}

시큐리티 설정(본 프로젝트는 WebSecurityConfig)

[9] application.yml 세팅

기본 설정 (각각 다른 파일에 있는 내용이 아니라 ---로 한 파일 내에서 구분 가능)
로컬 그룹은 로컬호스트의 8080 포트로 잡힌다
블루, 그린 그룹은 각각 public ip의 8080,8081 포트로 잡힌다

  
spring:
  profiles:
    active: local
    group:
      local: local, common, secret
      blue: blue, common, secret
      green: green, common, secret
server:
  env: blue

local 서버 설정

  
spring:
  config:
    activate:
      on-profile: local
kakao:
  redirect-uri: ---
server:
  port: 8080
  serverAddress: localhost

serverName: local_Server

local이 active 돼있을 때
blue 서버 설정

  
spring:
  config:
    activate:
      on-profile: blue
kakao:
  redirect-uri: ---
server:
  port: 8080
  serverAddress: 44.219.159.74

blue가 active 돼있을 때

green 서버 설정

  
spring:
  config:
    activate:
      on-profile: green
kakao:
  redirect-uri: ---
server:
  port: 8081

common 공통 파일 설정

  
spring:
  config:
    activate:
      on-profile: common
kakao:
  client-id: ---
  client-secret: ---

secret과 관련된 모든 파일
