闲的无聊，用spring3的mvc写了一个google的分页，这个小列子是基于注解的控制部分如下package com.my.google;

import java.util.ArrayList;import java.util.List;import java.util.Map;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import com.my.common.Dispatcher; /**  * @author 姜绵岳 * @version 创建时间：2011-4-9 下午05:02:51  * 一个类似google的分页的Action */@Controllerpublic class GoogleController{	/**	 * 一个类似谷歌的分页	 * @return	 */	@RequestMapping("/google")	public String google(HttpServletRequest request,HttpServletResponse response){		String pageNum=request.getParameter("page");	//当前页		int page=0;		if(null==pageNum||"".equals(pageNum)){			page=1;		}else{			page=Integer.parseInt(pageNum);		}		String forwardUrl="google.do?page=";		List
    
      list=new ArrayList
     
      ();	//存放模拟数据		for(int i=0;i<126;i++){			list.add("name xuehan "+i);		}		Dispatcher dispath=new Dispatcher();		Map map=dispath.getDispatch(forwardUrl, page, 10, list);		request.setAttribute("list",map.get("list"));		request.setAttribute("tag",map.get("tag"));		return "google";	}}

      {	/**	 * action调用分页方法 参数：forwordUrl 分页url,page当前页数,count每页显示条数,list要分页的集合	 */	public Map getDispatch(String forwardUrl, int page, int count, List
