마. Controller 에서 JSP 선택하기 위한 prefix 와 suffix 설정
# 현재코드
- 다음과 같은 문제가 있음.
return "/WEB-INF/views/hello.jsp"; <== 경로가 길다. 확장자가 jsp 로 고정되어있음.
# 수정코드
return "hello"; <== 파일명만 지정.
추가로 application.properties 에 파일경로와 확장자 정보를 알려줌.
# application.properties 에서 설정
# jsp 의 경로와 확장자 지정
spring.mvc.view.prefix=/WEB-INF/views/
