이번에는 Spring Legacy Project로 Spring MVC Project를 생성했을 때, Resources 폴더에 등록하여 Junit5에서 태스트했을 때 사용하는 방법에 대해서 소개하려고 한다.
간단하지만, 의외로 처음 셋팅을 시도했을 때, 오류가 많이 생긴다.
글 제목에는 Beans가 적혀져 있지만, 따로 Beans 용어를 소개하진 않겠다.
이 코드를 해독하거나 태스트를 해 보면, Bean의 감을 잠시 맛볼 수는 있다.
* IDE: Eclipse 2020-06
* Framework: Spring Framework 4.2.4
* Spring-core
* Spring-tx
* Spring-jdbc
* Spring-test
* AspectJ
* AspectJWeaver
* 출력 결과
JUnit5와 Spring Framework 4.2.4 Releases의 조합으로 태스트를 하였다.
그림 1. 출력 결과 - 콘솔
그림 2. 태스트 결과
1. 프로젝트 구성도
아래의 그림은 프로젝트 구성도이다.
주로 작업할 코드는 "TestUnit.java", "applicationContext.xml", "db.properties", "pom.xml"이다.
그림 3. 프로젝트 구성도
2. Java Compiler, Build Paths, Project Factes
/src/main/webapp/WEB-INF/lib에 oracle JDBC.jar(ojdbc.jar) 파일 넣어주기
* Java Compiler - compiler compliance level 1.8
* Build Path - JUnit 5, JRE System Library (JavaSE 1.8) 등
- Add Jar로 ojdbc.jar 파일 등록해주기
* Project Factes - Java : 1.8

* 맺음글(Conclusion)
연속해서 /src/main/webapp/WEB-INF/spring/root-context.xml 등의 작업을 소개하면 이해가 되지 않을 수 있어서 핵심 위주로 간단하지만,
중요한 키 포인트를 위주로 정리하였다.
환경 셋팅 관련해서 허공에 삽질을 적게 하였으면 하는 바람이다.
