아래의 dependency 추가 후 class 생성

ConnectionRunner

package com.web;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.stereotype.Service;

import com.web.jdbc.util.JDBCConnecttionManager;

@Service
public class ConnectionRunner implements ApplicationRunner{

	@Autowired
	private JDBCConnecttionManager connecttionManager;
	
	@Override
	public void run(ApplicationArguments args) throws Exception {
		// TODO Auto-generated method stub
		System.out.println("컨넥션 매니저 : " + connecttionManager.toString());
	}
}

Spring Boot Starters 사용

• 스타터는 필요한 라이브러리들을 관련된 것띠리 묶어서 마치 팩키지처럼 제공
  따라서 프로젝트에 사용하고 싶은 모듈이 있으면 그 모듈에 해당하는 스타터만
  의존성 추가하면 됨

BoardAutoConfiguration

package com.web.jdbc.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.web.jdbc.util.JDBCConnecttionManager;

@Configuration
public class BoardAutoConfiguration {

해당 프로젝트 내 src/main/ 에 resources 폴더 추가
그 안에 META-INF 폴더 추가

---

spring.factories

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.web.jdbc.config.BoardAutoConfiguration

추가 후 properties 확인후 Maven clean > install
target 폴더에 P04_board-spring-boot-starter-0.0.1-SNAPSHOT.jar 생김

---

P04 pom.xml 에서

	<groupId>com.web</groupId>
	<artifactId>P04_board-spring-boot-starter</artifactId>
	<version>0.0.1-SNAPSHOT</version>

복사 후

P03 pom.xml 에 dependency 로 추가

Maven Dependencies 확인 해 보면 가장 아래에 P04가 추가되어 있는 것을 확인 가능
