分页控件

该分页控件分成了客户端与服务端两部分：

<?xml version="1.0" encoding="utf-8"?><s:HGroup xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx"><fx:Declarations></fx:Declarations><fx:Metadata>[Event(name="page_change",type="common.dividePage.PageEvent")]</fx:Metadata><fx:Script></fx:Script><s:Button id="topPageBtn" label="首页" click="topPageBtn_clickHandler(event)"/><s:Button id="lastPageBtn" label="上一页" enabled="{page.cur-1>0}" click="lastPageBtn_clickHandler(event)"/><s:ComboBox id="pageComBox"width="40"change="pageComBox_changeHandler(event)"/><s:Button id="nextPageBtn" label="下一页" enabled="{enabledNext(page.cur+1,page.total/page.size+1)}" click="nextPageBtn_clickHandler(event)"/><s:Button id="bottomPageBtn" label="尾页" click="bottomPageBtn_clickHandler(event)"/></s:HGroup>

事件代码：

package common.dividePage{import backdcms.Page;import flash.events.Event;public class PageEvent extends Event{private var _page:Page;public static const PAGECHANGE:String="page_change";public function PageEvent(type:String, page:Page){this.page=page;super(type);}public function get page():Page{return _page;}public function set page(value:Page):void{_page=value;}}}

分页对象，包括封装了起始页，页数，总条数，返回结果等：

package backdcms{import mx.collections.ArrayCollection;[RemoteClass(alias="com.backdcms.model.Page")] [Bindable] public class Page { private var _cur:int=1; private var _size:int=6; private var _total:int=1; private var _result:ArrayCollection;public function Page() { } public function get result():ArrayCollection{return _result;}public function set result(value:ArrayCollection):void{_result = value;}public function get cur():int{ return _cur; } public function set cur(pData:int):void{ _cur=pData; } public function get size():int{ return _size; } public function set size(pData:int):void{ _size=pData; } public function get total():int{ return _total; } public function set total(pData:int):void{ _total=pData; } } }

服务端分页对象代码：

/** * */package com.backdcms.model;import java.util.List;/** * @author Administrator * */public class Page {private int cur = 1;private int size = 6;private Integer total = 1;private List result;public int getCur() {return this.cur;}public void setCur(int cur) {this.cur = cur;}public int getSize() {return this.size;}public List getResult() {return result;}public void setResult(List result) {this.result = result;}public void setSize(int size) {this.size = size;}public Integer getTotal() {return this.total;}public void setTotal(Integer total) {this.total = total;}}

业务代码：

@Overridepublic Page findTusers(Page page) {page.setTotal(this.getRows());page.setResult(tuserDao.getPagesEntity(page, "from Tuser"));page.setTotal(getRows());return page;}@Overridepublic Integer getRows() {return tuserDao.getRows("select count(*) from Tuser");}

Dao层的实现

@Overridepublic List<T> getPagesEntity(Page page, final String hql) {Session session = getSession();Query query = session.createQuery(hql);query.setFirstResult((page.getCur() - 1) * page.getSize());query.setMaxResults(page.getSize());return query.list();// final int size1 = page.getSize();// final int startRow = (page.getCur() - 1) * page.getSize();// return this.getHibernateTemplate().executeFind(new// HibernateCallback() {// public List doInHibernate(Session session)// throws HibernateException {// Query query = session.createQuery(hql);// query.setFirstResult(startRow);// query.setMaxResults(size1);// return query.list();// }// });}public Integer getRows(String sql) {Session session = getSession();// Query query = session.createSQLQuery(sql);Number number = ((Number) session.createQuery(sql).iterate().next());return number.intValue();}
