jsp的一套pager-taglib的使用總結

1，使用前的條件

①,jar包:pager-talib

2,實作

①,jsp頁面:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@ taglib uri="/struts-tags" prefix="s"%>

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<%@ taglib uri="http://jsptags.com/tags/navigation/pager" prefix="pg"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<title>this is the test pagination jsp</title>

.goodsDiv{

positon:relative;

width:100px;

height:30px;

border:1px;

}

</style>

</head>

<body>

<s:iterator value="pageList" id="goods" status="s">

</s:iterator>

<pg:pager items="${total}" url="goodAction!findPage" maxPageItems="5" export="offset,currentPageNumber=pageNumber" >

<pg:index>

<pg:first><a href="${pageUrl}" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" ><nobr>[首頁]</nobr></a></pg:first>

<pg:prev><a href="${pageUrl}" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" >前一頁</a></pg:prev>

<pg:pages>

<c:choose>

<c:when test="${currentPageNumber eq pageNumber}">

<font color="red">${pageNumber }</font>

</c:when>

<c:otherwise>

<a href="${pageUrl}" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" >${pageNumber}</a>

</c:otherwise>

</c:choose>

</pg:pages>

<pg:next><a href="${pageUrl}" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" >下一頁</a></pg:next>

<pg:last><a href="${pageUrl}" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" ><nobr>[尾頁]</nobr></a></pg:last>

</pg:index>

</pg:pager>

</body>

</html>

②,action中的實作

package com.ibm.action;

import java.util.ArrayList;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.ServletActionContext;

import com.ibm.bean.Goods;

import com.ibm.dao.GoodDao;

import com.opensymphony.xwork2.ActionSupport;

public class GoodAction extends ActionSupport {

private static final long serialVersionUID = -1740926729732013381L;

private GoodDao goodDao = new GoodDao();

private List<Goods> goodsList = goodDao.loadAll();// ��Ʒ��

private List<Goods> pageList = new ArrayList<Goods>();// ÿҳҪ��ʾ��Ʒ��

private Integer total = goodsList.size();// ��Ʒ��

private Integer offset;// �ӵڼ��ݿ�ʼ��

public Integer getTotal() {

return total;

}

public void setTotal(Integer total) {

this.total = total;

}

public String findPage() {

HttpServletRequest request = ServletActionContext.getRequest();

if (request.getParameter("pager.offset") == null) {

offset = 0;

System.out.println("findPage:================================"+"if");

} else {

offset = Integer.parseInt(request.getParameter("pager.offset"));

System.out.println("findPage:================================"+"else");

}

// 5��ʾÿҳ��ʾ5��,�ο�ҳ�� maxPageItems="5"��Ƕ�Ӧ��

pageList = goodDao.loadPage(offset, 5);

return "findPage";

}

public List<Goods> getPageList() {

return pageList;

}

public void setPageList(List<Goods> pageList) {

this.pageList = pageList;

}

public Integer getOffset() {

return offset;

}

public void setOffset(Integer offset) {

this.offset = offset;

}

③,dao裡面傳資料,自己用的測試的dao

package com.ibm.dao;

import java.util.ArrayList;

import java.util.List;

import com.ibm.bean.Goods;

public class GoodDao {

public List<Goods>loadAll(){

List<Goods> goods=new ArrayList<Goods>();

Goods goods1=new Goods(1,"food",1);

Goods goods2=new Goods(2,"food",2);

Goods goods3=new Goods(3,"food",3);

Goods goods4=new Goods(4,"food",4);

Goods goods5=new Goods(4,"food",4);

Goods goods6=new Goods(4,"food",4);

Goods goods7=new Goods(4,"food",4);

Goods goods8=new Goods(4,"food",4);

Goods goods9=new Goods(4,"food",4);

Goods goods10=new Goods(4,"food",4);

Goods goods11=new Goods(4,"food",4);

goods.add(goods1);

goods.add(goods2);

goods.add(goods3);

goods.add(goods4);

goods.add(goods5);

goods.add(goods6);

goods.add(goods7);

goods.add(goods8);

goods.add(goods9);

goods.add(goods10);

goods.add(goods11);

return goods;

}

@SuppressWarnings("unchecked")

public List<Goods> loadPage(int offser,int pagesize){

List<Goods> goods=new ArrayList<Goods>();

Goods goods1=new Goods(1,"food",1);

Goods goods2=new Goods(2,"food",2);

Goods goods3=new Goods(3,"food",3);

Goods goods4=new Goods(4,"food",4);

Goods goods5=new Goods(4,"food",4);

Goods goods6=new Goods(4,"food",4);

Goods goods7=new Goods(4,"food",4);

Goods goods8=new Goods(4,"food",4);

Goods goods9=new Goods(4,"food",4);

Goods goods10=new Goods(4,"food",4);

Goods goods11=new Goods(4,"food",4);

goods.add(goods1);

goods.add(goods2);

goods.add(goods3);

goods.add(goods4);

goods.add(goods5);

goods.add(goods6);

goods.add(goods7);

goods.add(goods8);

goods.add(goods9);

goods.add(goods10);

goods.add(goods11);

return goods;

}

④,javabean

package com.ibm.bean;

import java.io.Serializable;

public class Goods implements Serializable{

private static final long serialVersionUID = 4359412889831254896L;

private Integer id;

private String goodName;

private Integer goodType;

public Goods(Integer id, String goodName, Integer goodType) {

super();

this.id = id;

this.goodName = goodName;

this.goodType = goodType;

}

public Integer getId() {

return id;

}

public void setId(Integer id) {

this.id = id;

}

public String getGoodName() {

return goodName;

}

public void setGoodName(String goodName) {

this.goodName = goodName;

}

public Integer getGoodType() {

return goodType;

}

public void setGoodType(Integer goodType) {

this.goodType = goodType;

}
