도도의 초록누리

* 웹 서버: Apache Tomcat 9

  - JSP/Servlet 기초 이해력

* 라이브러리: Maven(메이븐)

* Spring 프레임워크없이, JSP/Servlet 기반으로 MVC2를 직접 구현할 수 있는 수준

운영체제: Microsoft Windows 10

개발환경: Spring Tool-Suite 4-4.7.2. Release (Eclipse 기반 개발)

웹 서버: apache-tomcat-9.0.37-windows-x64

의외로 쉽게 MVC 프로젝트가 생성되는 것을 확인할 수 있다.

참고로 com.springMVC1.web으로 작성하면, 태스트 배포 주소는 "홈페이지주소:8080/web"이 된다.

정정: 

(1) HomeController.class -> BoardController.class로 변경 (탈자)
(2) Welcome home: The ..... -> Welcome board: The...로 변경

적용 대상: Eclipse IDE 기반의 프로그램 (사용가능) // 웹 프로젝트의 예

- 문자 집합(Character Set): 사람이 사용하는 문자를 컴퓨터가 이해하는 기호로 표현하기 위해 문자를 각 코드(숫자)에 매칭 시킨 것

  컴퓨터에서 문자를 처리하려면 인코딩, 디코딩 과정이 필요하다.
  (예: 컴퓨터라는 게 아날로그, 디지털 이런 형태가 있다고 하면 흔히 1,0로 구성되어 있기 때문이다. - 쉽게 이해를 돕기 위해서 작성함.)

- 인코딩(Encoding)/부호화: 각 문자를 특정 기호로 변환.

  ex) 유니코드를 UTF-8로 인코딩

- 디코딩(Decoding)/복호화: 변환된 기호를 다시 문자로 변환
