자바 스프링 게시판(@Controller, @RequestMapping을 이용하여 Controller변경) Spring 게시판 구현

자바 스프링 게시판(@Controller, @RequestMapping을 이용하여 Controller변경)  

Spring 게시판 구현(게시판 컨트롤러 변경, @Controller, @RequestMapping)

:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 

1.     시작하기

 

지금까지 게시판에서 사용했던 BoardMultiController를 Spring2.5이상에서 지원하는 @Controller, @RequestMapping, @RequestParam을 이용하여 변경하자.

 

2, 4번과 같이 두 개의 파일을 수정하자.

 

1. 기존 BoardMultiController.java

2. 새로 작성할 BoardMultiController.java

3. 기존 action-servlet.xml

4. 새로 작성할 action-servlet.xml

 

 

 

1. 기존 BoardMultiController.java

 

package onj.board.controller;

import java.io.PrintWriter;
import java.util.Enumeration;
import java.util.List;

public class BoardMultiController extends MultiActionController {
 private BoardService boardService;

 public void setBoardService(BoardService boardService) {
  this.boardService = boardService;
 }

 // 게시판 리스트 보기, 페이징 기능은 구현 안함

   out.println("<script>history.go(-1);</script>");
   return null;
  } else {
   return new ModelAndView("redirect:/list.html");
  }
 }

 // 게시물상세보기에서 답변 클릭시 호출되어 답변달 reply.jsp로 연결
 public ModelAndView reply(HttpServletRequest req, HttpServletResponse res) throws Exception {

  String seq = req.getParameter("seq");

  // 답변달 게시물 내용을 reply.jsp 넘긴다.
  ModelAndView mav = new ModelAndView("reply",   //view이름
                                "reply",   //readContent가 넘기는 boardDTO의 이름, reply.jsp에서 사용
                                boardService.readContent(seq));
 
  return mav;
 }

 // 답글 저장
 public ModelAndView replyok(HttpServletRequest req, HttpServletResponse res)
   throws Exception {
