프로젝트 생성 & 환경 설정

만약 Spring MVC Project가 없을 경우에 워크스페이스에

.metadata\.plugins\org.springsource.ide.eclipse.commons.content.core

https-content.xml
0.02MB

해당 파일을 넣을 것

Next로 가서 패키지 이름 생성 해줄것 (kr.or.ddit)

라이브러리 설정 - JAVA

라이브러리 설정 - 서버

톰캣 설정

서버 설정

톰캣 설정 후

포트 80변경
주소 설정

Project Facets 설정

속도 빠르게하는법

pom.xml 변경

pom.xml
메이븐(maven)은 프로젝트를 생성하고 라이브러리를 관리하고 빌드하는 것까지 프로젝트의
라이프 사이클을 관리하는 소프트웨어.
즉, 자동으로 라이브러리를 사용할 수 있게 해줌

java버전과 스프링프레임워크 버전 변경

pom.xml이 수정되면 Maven빌드를 통해 변경된 Maven 내용을 프로젝트에 반영해야 함

apply

해당 console이 뜨면 정상적으로 pom.xml이 업데이트된 것을 확인할 수 있다
