jsp分页？该怎么处理

public class Serch extends ActionSupport{   private  String  bid;   private  String  bname;   private  int    number;   private int k;//储存最大页面数   private int pageNow=1; //页码数,初始为1   private int pageSize = 5 ; //页面行数    private int intRowCount;//总行数   private int intPageCount;//总页数   private int lastPage;   private int p=1;.....set/get;public String execute() throws Exception {    List list=new List();    java.util.List L=new  ArrayList();    L=list.list();    intRowCount=L.size();    System.out.println("链表的长度："+L.size());    if(L.size()%pageSize==0) //判断分多少页          this.lastPage=L.size()/pageSize;    else        this.lastPage=L.size()/pageSize+1;        this.setIntPageCount(this.lastPage);//存入总页数        if(this.pageNow<1)//如果当前页码是第一页在点第一页的时候也跳转到第一页        this.pageNow=1;    if(this.pageNow>this.lastPage)//同理只不过是最后一页        this.pageNow=this.lastPage;    /*     *      * 假设取其中20-25条     *      *      *      */  int startIndex=(this.pageNow-1)*pageSize;//截止条目开始，第20条  int endIndex=startIndex+pageSize;//截止条目结束     第25条    if(endIndex>=L.size())      endIndex=L.size();   L= L.subList(startIndex, endIndex);  System.out.println("执行");      ActionContext.getContext().put("list", L);    return  "success";}@Overridepublic void validate() {    // TODO Auto-generated method stub    super.validate();}}前台显示：共<s:property value="intRowCount"/>记录&nbsp;&nbsp;共<s:property value="intPageCount"/>页&nbsp;&nbsp;        第<s:property value="pageNow"/>页&nbsp;&nbsp; <s:url action="Serch.action" id="url">                <s:param name="pageNow">                    <s:property value="1" />                </s:param>            </s:url>  <s:a href="%{url}">首页</s:a>    &nbsp;&nbsp;              <s:url action="Serch.action" id="url">                <s:param name="pageNow">                    <s:property value="%{pageNow-1}" />                </s:param>            </s:url>  <s:a href="%{url}">上一页</s:a>    &nbsp;&nbsp; <s:url action="Serch.action" id="url">                <s:param name="pageNow">                    <s:property value="%{pageNow+1}" />                </s:param>            </s:url>  <s:a href="%{url}">下一页</s:a>    &nbsp;&nbsp;<s:url action="Serch.action" id="url">                <s:param name="pageNow">                    <s:property value="lastPage" />                </s:param>            </s:url>  <s:a href="%{url}">尾页</s:a>
