leavemessage.java

这个网上商城系统项目是我之前发过类似的一个大的整合

package servlet;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;

import javabean.LeaveWord;
import javabean.Member;
import javabean.Orders;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import dao.RegisterDAO;

public class LeaveMessage extends HttpServlet {
	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		request.setCharacterEncoding("gbk");
		response.setContentType("text/html;charset=gbk");
		PrintWriter out = response.getWriter();
		RegisterDAO dao = new RegisterDAO();
		
		//留言管理
		Object obj = request.getSession().getAttribute("userName");
		if(obj == null){
			response.sendRedirect("/EShopping/sorry.jsp");
		}else {
			//根据自己的名字查
			String userName = (String)obj;
			Member member = dao.ToModRegister(userName);
			int memberid = member.getId();
			String sql = "select * from leaveword where memberid=" + memberid;
			ArrayList<LeaveWord> arrayList = dao.ListLeaveWord(sql);
			
			request.setAttribute("arrayList", arrayList);
			request.getRequestDispatcher("/leaveword.jsp").include(request, response);
		}
		
		out.flush();
		out.close();
	}

	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		this.doGet(request, response);
	}

}
