[Spring Batch] 프로젝트 생성

https://start.spring.io/

Spring Initializr 를 통한 스프링 부트 프로젝트 생성

프로젝트 의존성

• Lombok
• Spring Web
• JDBC API
• Spring Data JPA
• MySQL Driver
• Spring Batch

Gradle

패키지 생성 : 앞으로 여러 클래스 작성을 위해

• batch
• config
• controller
• entity
• repository
• schedule

패키지 생성

2개의 데이터 베이스 연결

1. meta_db

• 배치 작업의 진행 사항 및 내용에 대한 메타데이터를 기록하는 테이블을 위한 DB

2. data_db

• 배치 작업 데이터용 DB

데이터베이스 연결 변수 application.yml
