1. 리스트보기에서 본문 미리보기용 서블릿(ajax)

package onj.board.ajaxpreview;

import java.io.IOException;

import java.io.PrintWriter;

import javax.servlet.ServletException;

import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import onj.board.service.BoardService;

import onj.board.service.BoardServiceHelper;

//Servlet3.0이상, Tomcat7 이상에서는 애노테이션으로 서블릿 정의가 가능하다.

@WebServlet(urlPatterns = "/preView")

public class ContentPreview extends HttpServlet {

protected void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {

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

req.setCharacterEncoding("utf-8");

res.setContentType("text/html; charset=utf-8");

res.setHeader("Cache-Control",  "no-cache");

BoardService boardService = BoardServiceHelper.getBoardService(getServletContext());

PrintWriter out = res.getWriter();

out.println("<pre>" + boardService.preView(seq) + "<pre>");

}

}

2. Spring AOP용 Aspect클래스

package onj.board.aop;

import onj.board.dao.BoardDAO;

import onj.board.dao.LoggingDAO;

import org.aspectj.lang.JoinPoint;

import org.aspectj.lang.annotation.Aspect;

import org.aspectj.lang.annotation.AfterReturning;

import org.springframework.beans.factory.annotation.Autowired;

@Aspect

public class LoggingAspect {

@Autowired

private LoggingDAO loggingDAO;

@Autowired

private BoardDAO boardDAO;

// 사후충고(반드시 정상 리턴 후 호출)

// BoardDAOImpl의 모든메소드중 파라미터가 1개 있는 메소드가 충고받을 포인트컷

// 본 게시판에는 리스트보기와 , getSql() 만 메소드 파라미터가 없어 충고 적용 안됨

@AfterReturning(pointcut="execution(* onj.board.dao.BoardDAOImpl.*(*))", returning="result")

public void logAfterReturning(JoinPoint joinPoint) {

System.out.println("<<<<<<<<< DAO 로깅 충고 실행");

loggingDAO.writeLog(joinPoint.getSignature().getName(), boardDAO.getSql());

}

}

3. 컨트롤러
