servlet-context.xml vs root-context.xml vs web.xml

servlet-context.xml

  • 요청과 관련된 객체
  • controller나, @(어노테이션), ViewResolver, Interceptor, MultipartResolve 설정

root-context.xml

  • view완 관련되지 않은 객체
  • Service, Repository(DAO), DB등 비즈니스 로직 설정

web.xml

  • 설정을 위한 설정 파일
  • WAS가 최초로 구동될 때, 각종 설정을 정의 (엔코딩)
  • xml파일을 인식하도록 각 파일을 가리켜 준다 (servlet, root-context.xml)

@data getter setter issue

lombok은 lib가 있어도 따로 설치해줘야함.
1 lombok lib가 있는 곳으로 nav
2 java -jar lombok-1.16.10.jar
3 다시 이클립스 실행 후 maven update, project clean.

setup gradle on existing project

1 check ver
2 add gradle nature
