톰캣 서버 세팅

apache-tomcat-9.0.35 다운로드

https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.35/bin/

Index of /dist/tomcat/tomcat-9/v9.0.35/bin

archive.apache.org

Window > Preference > Server 검색 > Runtime Environments

원래 있던거 지워주고 Add.. Apache Tomcat v9.0 선택하고 Apply and Close

아래의 Server 창에서 세팅을 마저 해준다.

포트번호 8181로 설정한것은 오라클서버가 8181이므로 겹치지 않게 하기 위함이다.

New project > Dynamic Web Project를 선택해서 새 프로젝트 생성한다.

Spring Lib 추가

해당프로젝트 폴더의 WebContent > WEB-INF > lib 에 SpringLib 복사해서 넣는다.

WEB-INF에 Spring Bean Configuration File 생성한다.

Java Resources > Libraries > Web App Libraries > org.springframework.web.servlet-3.1.4.RELEASE.jar > org.springframework.web.servlet.handler > SimpleUrlHandlerMapping.class 선택해서 경로복사(Copy Qualified Name)

DispatcherDispatcherServlet가 불려지면서 SpringController-servlet.xml파일로 간다.

(FrontController가 DipspatcherServlet)

Controller는 Service를 Service는 Dao를 불러줘야한다.

Controller는 Service의 , Service는 Dao의 생성자와 Setter 메소드를 가져야한다.

Controller -> Service -> Dao -> Mybatis

DB연동을 위한 .jar파일을 라이브러리 폴더에 추가

한글 인코딩을 위한 filter 작성

메인페이지

web.xml

--> FrontController가 DispatcherServlet으로 대체

(매핑작업, 페이지 이동 작업,

서버가 켜지면 *.do가 들어오고 DispatcherServlet을 찾음

servlet-name은 아무거나 해도 되지만, beans파일과 이름이 같아야함

[정리] *** MVC - FrontController : Spring MVC ***

FrontController: DispatcherServlet

1-1) DispatcherServlet는 FrontController 역할을 하지만, 웹 요청 URL과 Command 맵핑한 정보를 관리하는 기능을 가지고 있지 않다.
1-2) DispatcherServlet은 HandlerMapping을 참조하고 처리를 컨트롤러에게 맡긴다.

FrontController-Map : HandlerMapping interface
2-1) BeanNameUrlHandlerMapping
2-2) SimpleUrlHandlerMapping : 요청 URL을 일괄처리한다.
2-3) ClassNameHandlerMapping

FrontController-Command Pattern : 각각의 Controller에 해당되는 클래스(인터페이스)를 상속받아 구현한다.
3-1) Controller
3-2) AbstractController
3-3) AbstractControllerController
3-4) SimpleFormController
3-5) MultiActionController : 해당 URL에서 함수를 찾는다.

FrontController-String viewPage : View interface
4-1) InternalResourceView : 예제에서는 ModelAndView 사용.
4-2) JstlView
4-3) VelocityView
4-4) MappingJacksonJsonView

FrontController-forward(request, response) : ViewResolver interface
5-1) InternalResourceViewResolver
5-2) ResourceBundleViewResolver
5-3) VelocityViewResolver
