Ajax Struts JSP Apache CSS

最近做了个用ajax分页的简单例子，供一些初学者参看，事先声明，本人也是初学者，写的不好，也很粗略，请见谅啊

我是以最简单的商品列表为例子（商品名，商品价格，商品图片）数据库用的是My Sql 并运用了struts,hibernate

------------------------------------------------------------------------

jsp页面（main.jsp）：

<%@ page language="java" pageEncoding="utf-8" import="java.util.List,com.fy.pojo.Goods"%>

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>
<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html:html lang="true">
<%
   String temp = (String)request.getAttribute("temp");
   if(temp == null || "".equals(temp)){
     response.sendRedirect("/ajaxFY/main.do?method=getCount");
   }else{
   List goodsList = (List)request.getAttribute("goodsList");
   int count = (Integer)request.getAttribute("count");
   int pageCount = (count-1)/3+1;
   Goods goods = null;
%>
<head>

    <html:base />

    <title>main.jsp</title>

action（MainAction）：

/**
* 得到商品的数量
* @param mapping
* @param form
* @param request
* @param response
* @return
*/
public ActionForward getCount(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
  int count = goodsService.getCount();
  List goodsList = goodsService.getGoods(0,3);
  request.setAttribute("temp", "temp");
  request.setAttribute("count", count);
  request.setAttribute("goodsList", goodsList);
  return new ActionForward("/main.jsp");
}

/**
* 得到商品
* @param mapping
* @param form
* @param request
* @param response
* @return
*/
public ActionForward getGoods(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
  int firstResult = Integer.parseInt(request.getParameter("firstResult"));
  List goodsList = goodsService.getGoods(firstResult,3);
  Goods goods = null;
  PrintWriter out = null;
  response.setCharacterEncoding("utf-8");
  try {
   out = response.getWriter();
  } catch (IOException e1) {
   e1.printStackTrace();
  }
  for(int i=0;i<goodsList.size();i++){
   goods = (Goods)goodsList.get(i);
   out.print("<table>");
   out.print("<tr>");
   out.print("<td>商品名：</td>");
   out.print("<td>"+goods.getGoodsName()+"</td>");
   out.print("</tr>");
   out.print("<tr>");
   out.print("<td>商品价格：</td>");
   out.print("<td>$"+goods.getPrice()+"</td>");
   out.print("</tr>");
   out.print("<tr>");
   out.print("<td >商品图片：</td>");
   out.print("<td><img src='/ajaxFY/picture/"+goods.getPicture() +"' height='100' width='100'></img></td>");
   out.print("</tr>");
   out.print("</table><hr>");
  }
  out.flush();
  out.close();
  return null;
}
}
