channalservlet.java

一个简单的java web项目 基于servlet构建

package cn.dongsw.web;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Iterator;
import java.util.List;

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

import cn.dongsw.fw.BaseServlet;
import cn.dongsw.service.channal.ChannalService;

public class ChannalServlet extends BaseServlet  {
	
	private ChannalService service = new ChannalService();
	
	public void process(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		String parentId = request.getParameter("parentId");
		Integer level = Integer.parseInt(request.getParameter("level"));
		List list = service.findChnnalByParentId(parentId);
		Iterator it = list.iterator();
		PrintWriter out = null;
		response.setContentType("text/xml; charset=UTF-8");
		response.setHeader("Cache-Control", "no-cache");
		out = response.getWriter();
		level=level+1;
		out.println(level+"&<option selected=selected value='-1'>请选择--</option>");
		while(it.hasNext()){			
			Object[] obj = (Object[])it.next();
			out.println("<option value="+Long.parseLong((String)obj[0])+">"+(String)obj[1]+"</option>");
		}
		out.flush();
		out.close();
		//request.getRequestDispatcher("index.jsp").forward(request, response);
	}
