SpringMVC Template (4.* version) 환경설정 참고

[SpringMVC/MyBatis] Spring MVC Project 환경설정

[ 환경 설정 ] 1. Spring Legacy Project 프로젝트 생성 > 'Spring MVC Project' 선택 > 프로젝트 명 작성 (작성한 프로젝트 이름이 실제 브라우저상 보이는 서버프로그램 url 이 된다 *주로 프로젝트 명을 쓴다..

[ Spring MVC Template의 디렉토리 계층 구조 ]

/src/main/java - model, controller

/src/main/resources : MyBaits 설정파일 (mapper.xml), log4j.xml

* MyBatis 설정파일은 영속성 계층에 속하기 때문에 관례적으로 resource 폴더에 둔다.

/src/main/webapp/WEB-INF : DD(web.xml), Spring 설정파일(spring-model.xml, spring-web.xml)

/src/main/webapp/WEB-INF/views : 모든 jsp들

*webapp/WEB-INF 아래에 DD와 Spring설정파일을 두는 이유 : FrontController 패턴을 정확하게 지키기 위해서

→ 모든 클라이언트의 요청을 하나의 진입점으로 받아, DispatcherServlet을 거친 후 응답하게 하기 위해서이다 (보안성 향상)

: 모든 요청에 공통된 정책을 부여한다.

/src/test/java: - test class (Junit test)

/src/test/resources : test를 위한 sql파일들,log4j.xml

Maven pom 설정

나의 개발환경에 맞게 몇가지 버전 수정 및 추가를 해주었다. (주석으로 기재되었습니다!)

Spring configure 설정 - spring 설정이 여러개 !

spring설정을 model과 web으로 구분하여 분리

* namespace에서 'context' 체크

* typeAliasesPackage 설정 시, project명을 기재해주어 경로설정에 주의한다.
