설치환경

1.Help -Eclipse Market place
2. find 에서 sts 갬석
3. 인스톨
4. 대쉬보드만 풀기
5. confirm클릭
6. accept 후 finish 클릭
7. 무조건 동의하고 넘기기

• 특정목적을 지닌 프로그램 개발 시 개발에 필요한 기본 구조와 기능을 만들어 놓은 개발 가이드의 형태.
  추가 세팅

스프링 폴더 설명

서버올리기

1.톰캠 오른쪽 마우스 클릭후 add and remove
2.TestS add 하기

Spring workflow( 스프링 동작순서)

굉장히 중요하니 일단 암기하자 !!
