分页栏,,DAO层的代码分页代码:


DAO层的代码分页代码:public PageModel findByPageModel(String hql,PageModel pm) {        pm.setTotalCount(this.getHibernateTemplate().find(hql).size());        pm.setGoToHref(ServletActionContext.getRequest().getServletPath().replace("/",""));        int totalCount = pm.getTotalCount();        int pageSize = pm.getPageSize();        int totalPage = (totalCount+pageSize-1)/pageSize ;        int currentPage = pm.getCurrentPage() ;        pm.setTotalPage(totalPage);        int offset = (currentPage-1)*pageSize;        pm.setList(this.getSession().createQuery(hql).setFirstResult(offset).setMaxResults(pageSize).list());        return pm;    }分页的JAVABEAN:public class PageModel {    private int currentPage;    private int pageSize;    private int totalCount;    private int totalPage;    private List list ;    private String goToHref;    public int getCurrentPage() {        if(currentPage<=0) currentPage=1;        return currentPage;    }    public void setCurrentPage(int currentPage) {        this.currentPage = currentPage;    }    public int getPageSize() {        if(pageSize<=0) pageSize=10;        return pageSize;    }    public void setPageSize(int pageSize) {        this.pageSize = pageSize;    }    public int getTotalCount() {        return totalCount;    }    public void setTotalCount(int totalCount) {        this.totalCount = totalCount;    }    public int getTotalPage() {        return totalPage;    }    public void setTotalPage(int totalPage) {        this.totalPage = totalPage;    }    public List getList() {        return list;    }    public void setList(List list) {        this.list = list;    }    public String getGoToHref() {        return goToHref;    }    public void setGoToHref(String goToHref) {        this.goToHref = goToHref;    }}JSP页面:<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><link rel="stylesheet" type="text/css" href="<%=basePath %>findByHql/pagingBar/css/pagingBar.css">    <input type="button" class="firstPage commonPage"  alt="首页"   title="首页"/>    <input type="button" class="beforePage commonPage" alt="上一页" title="上一页"/>    <input type="button" class="nextPage commonPage"   alt="下一页" title="下一页"/>    <input type="button" class="lastPage commonPage"   alt="尾页"   title="尾页" />    <input type="hidden" id="currentPage" value="${requestScope.pm.currentPage }" />    <input type="hidden" id="totalPage"  value="${requestScope.pm.totalPage }" />    <input type="hidden" id="goToHref"   value="${requestScope.pm.goToHref }" />    <span class="cp">当前第${requestScope.pm.currentPage }页</span>    <span class="tc"> 相关资讯:${requestScope.pm.totalCount }条</span>    <span class="ps">每页${requestScope.pm.pageSize }条 </span>    <span class="tp">共${requestScope.pm.totalPage}页</span><script type="text/javascript" src="<%=basePath%>js/jquery.js"></script><script type="text/javascript">    (function($) {        var currentPage = parseInt($('#currentPage').val());        var totalPage = parseInt($('#totalPage').val());        var toHref = $('#goToHref').val();        $('.firstPage').bind('click', function() {            goToHref(1);        });        $('.nextPage').bind('click', function() {            if (currentPage >= totalPage)                goToHref(totalPage);            else                goToHref(currentPage + 1);        });        $('.beforePage').bind('click', function() {            if (currentPage <= 1)                goToHref(1);            else                goToHref(currentPage - 1);        });        $('.lastPage').bind('click', function() {            goToHref(totalPage);        });        function goToHref(cp) {            document.location.href = toHref+"?currentPage=" + cp;        }    })(jQuery)</script>CSS:下面有几张图片需要自己找.../*点击栏*/.commonPage{    width: 16px;    height: 16px;    border: none;    cursor: pointer;}.firstPage{    background: url("../images/page-first.png") no-repeat;}.nextPage{    background: url("../images/page-next.png") no-repeat;}.beforePage{    background: url("../images/page-prev.png") no-repeat;}.lastPage{    background: url("../images/page-last.png") no-repeat;}/*显示栏*/.cp,.tc,.ps,.tp{    font-size: 14px;}在action中调用DAO层的方法,给currentPage和pageSize设置初始值,然后就返回一个list到你分页的页面迭代,以后就直接嵌套在分页页面中就行//该片段来自于http://byrx.net
