DetailController.java

package controller; import java.util.HashMap; import java.util.Map; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import logic.Board; import org.springframework.web.bind.RequestUtils; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.AbstractController; import vo.BoardVO; public class DetailController extends AbstractController {    private Board board = null;    public void setBoard(Board board) {   this.board = board;  }    @Override  protected ModelAndView handleRequestInternal(HttpServletRequest req,    HttpServletResponse res) throws Exception {   // TODO Auto-generated method stub      int boardIdx = RequestUtils.getIntParameter(req, "boardIdx");        BoardVO boardDetail = board.getBoardDetail(boardIdx);   Map model = new HashMap();   model.put("boardDetail", boardDetail);      ModelAndView modelAndView = new ModelAndView();   modelAndView.setViewName("detail");   modelAndView.addAllObjects(model);      return modelAndView;  } }

.AbstractController 클래스
  -Controller 인터페이스를 구현항 추상 클래스
  -다음과 같은 프로퍼티 설정이 가능

프로퍼티	디폴트	설명
supportedMethods	GET, POST	.허가하는 리퀘스트 메소드를 정의 .쉼표 구분으로 복수 지정 가능 .위반 시 Request MethodNotSupported Exception throw
requireSession	False	.Session의 존재가 필수인지 아닌지를 지정 .Session이 확인되지 않을 경우에는 SessionRequired Exception throw
cacheSession	-1	.HTTP header에 기재하는 cache의 유효 기간을 초단위로 지정 .'0' : No-cache .'-1' : cache header를 작성하지 않음
synchronizeOnSession	False	.HttpSession 오브젝트 상에서 handleRequestInternal()메소드의 호출을 동기화할지 안 할지는 지정

*** 위 프로퍼티에 관해서는 나중에 따로 정리를 하겠음.
