[21일차] spring MVC 예제 - 4 (MultiActionController)

전체소스를 따로 제공하지 않음.
MultiActionController가 어떻게 구현하는지만 알고 넘어감.
다음 강좌(?)에서 MultiActionController를 이용하여 게시판(CRUD)을 구현

BoardController.java

package controller; import java.util.List; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import logic.BoardLogic; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.multiaction.MultiActionController; import vo.BoardVO; public class BoardController extends MultiActionController {  private BoardLogic boardLogic;    public void setBoardLogic(BoardLogic boardLogic) {   this.boardLogic = boardLogic;  }      //boardList  public ModelAndView boardList(HttpServletRequest request, HttpServletResponse response) throws Exception{   List<BoardVO> boardList = boardLogic.getBoardList();      for(int i=0; i<boardList.size(); i++){    BoardVO boardVo = boardList.get(i);    System.out.println(i + " : " + boardVo.getTitle());   }   ModelAndView modelAndView = new ModelAndView("board/boardList");   modelAndView.addObject("boardList", boardList);      return modelAndView;  }      //boardDetail  public ModelAndView boardDetail(HttpServletRequest request, HttpServletResponse response) throws Exception{   int boardSeq = Integer.parseInt(request.getParameter("boardIdx"));      BoardVO boardDetail = boardLogic.getBoardDetail(boardSeq);      ModelAndView modelAndView = new ModelAndView("board/boardDetail");   modelAndView.addObject("boardDetail", boardDetail);      return modelAndView;  }      //boardUpdate  public ModelAndView boardUpdate(HttpServletRequest request, HttpServletResponse response) throws Exception{   int boardSeq = Integer.parseInt(request.getParameter("boardIdx"));      BoardVO boardVo = boardLogic.getBoardDetail(boardSeq);      ModelAndView modelAndView = new ModelAndView("board/boardUpdate");   modelAndView.addObject("boardVo", boardVo);      return modelAndView;  }      //boardDelete  public ModelAndView boardDelete(HttpServletRequest request, HttpServletResponse response) throws Exception{      //구현부분      return null;  }   }

※ MultiActionController 클래스
  - MultiActionController 클래스를 계승한 리퀘스트 컨트롤러(위에서는 BoardController)는 복수의 리퀘스트에 대해서 각각의 처리를 하나의 클래스에 기술하고 리퀘스트 별로 할당할 수 있음.
  - MultiActionController 클래스를 계승한 경우의 호출 메소드 시그너쳐

public ModelAndView methodName(HttpServletRequest request, HttpServletResponse response) throws Exception{   ... ... }

  - 리퀘스트 URL과 메소드를 관련 짓기 위해서는 스프링 MVC가 제공하는 MethodNameResolver 인터페이스를 이용한다.(위 예제에서는 MethodNameResolver 인터페이스의 구현 클래스인 PropertiesMethodNameResolver 클래스 이용)
  - 서블릿명-servlet.xml의 설정파일에 리퀘스트 URL과 메소드의 관련성을 정의(아래 xml 참조)
