    • [Spring] 01-6. 컨트롤러 구현 및 전체적인 실행과정
      프로그래밍/Spring 2015. 9. 11. 11:24
      반응형


      SPRING 3.0버전부터는 @Controller Annotation을 이용해서 컨트롤러 Class를 구현하도록 권장하고 있으며 기존의 Controller Interface와 AbstractController Class, AbstractCommandController Class 등은 이제 고전 컨트롤러 (ClassicController)로 불리고 있다.


      @ModelAttribute Annotation을 이용해서 커맨드 객체의 모델 이름을 지정했다면, 뷰 Code에서는 다음과 같이 해당 모델 이름을 사용해서 커맨드 객체에 접근할 수 있다.

      제목 : ${command.title}
