| 1. 파이썬 설치하기 (0) | 2017.01.11 |
윈도우에서 파이썬(Python)을 설치하는 방법입니다.
먼저 http://www.python.org/ 홈페이지에 접속합니다.
Downloads 메뉴를 클릭하면 파이썬을 다운로드 받을 수 있습니다.
2017년 1월 현재 최신버전은 Python 3.6.0과 2.7.13입니다.
파이썬의 3.X버전과 2.X 버전의 차이가 크기때문에 두개 모두 사용하고 있습니다.
이 블로그에서는 3버전에 대해 포스팅 할 예정이므로 이 블로그를 참고하실 분은 3버전을 다운받아 주시길 바랍니다.
설치파일을 실행한 상태 입니다.
Install Now를 클릭해 주시면 아래 사진과 같이 설치를 시작합니다.
설치가 완료되었으면 Close를 눌러 완료합니다.
이제 파이썬 사용을 위한 준비가 끝났습니다.

STS(스프링) 에서 한글이 깨지는 이유는 기본 인코딩이 MS949로 되어 있어서 한글이 깨진다.
인코딩을 모두 UTF-8로 변경을 해주어야 한글이 깨지지 않는다.
먼저 Window - Preferences 로 들어가준다.
CSS, HTML, JSP 항목에서 Encoding 항목을 ISO 10646/Unicode(UTF-8)로 변경해 준다.
General -> Workspace의 Text file encoiding 을 UTF-8로 바꿔준다.
General -> Web Brower에서 New를 누른후 Chrome을 설정한다.
Location은 Chrome이 설치된 위치를 지정한다.
Spring Legacy Project로 새로운 Project를 생성한다.
Project Name을 입력하고, Spring MVC Project를 선택한후 Next를 누른다.
네모칸을 채운후 Finish를 누른다.
처음 프로젝트를 생성하면 빨간색 X표가 뜨는데 자동으로 설치가 된 후에 x표가 사라진다.
