04第四讲商品信息录入功能实现

1、商场 VIP 消费情况查询系统商品信息录入功能实现一、添加商品信息录入窗口按钮事件处理效果预览：二、添加表单text:商品信息录入modityAddfunction commodityAdd() /创建一个windowvar commodityAddWindow = new Ext.Window( titlt:商品信息录入,width:400,height:300, modal:true);commodityAddWindow.show();/创建表单var formPanel = new Ext.form.FormPanel( bodyStyle:padding-left:50px, wid

2、th:400,frame:true, labelAlign:right, monitorValid:true, items:new Ext.form.TextField( id:commodityName, name:commodityName,fieldLabel:商品名称, minLength:2,minLengthText:商品名称长度不能小于2个字符, maxLength:12,maxLengthText:商品名称长度不能大于12个字符, allowBl:false,blText:商品名称不能为空),new Ext.form.NumberField( id:price,name:pri

3、ce, fieldLabel:商品价格,allowNegative : false,/不允许输入负数 nanText :请输入有效的整数,/无效数字提示 allowDecimals : true,/允许输入小数 maxValue : 10000000,/最大值minValue : 0,/最小值mext:商品价格不能小于0元, maxText:商品价格不能大于0元,效果预览：allowBl:false,blText:商品价格不能为空),new Ext.form.NumberField( id:agio,name:agio, fieldLabel:商品折扣,allowNegative : fals

4、e,/不允许输入负数 nanText :请输入有效的整数,/无效数字提示 allowDecimals : true,/允许输入小数 maxValue : 1,/最大值minValue : 0,/最小值mext:商品折扣不能小于0,maxText:商品折扣不能大于0, allowBl:false,blText:商品折扣不能为空),buttons:text:添加,formBind:true,handler:function(),text:重置,handler:function() formPanel.getForm().reset(););三、商品信息 PO 类、1.PO 类文件以及接口类pack

5、age com.ibeifeng.po;import java.util.HashSet; import java.util.Set;/* commodity entity. author MyEclipse Persistence Tools*/public class Commodityimplements java.io.Serializable / Fieldsprivateeger commodityId; private String commodityName; private Double price;private Double agio;private Set consum

6、es = new HashSet(0);/ Constructors/* default constructor */ public Commodity() /* full constructor */public Commodity(String commodityName, Double price, Double agio, Set consumes) modityName = commodityName; this.price = price;this.agio = agio; this.consumes = consumes;/ Property acsorspublicegermo

7、dityId() returnmodityId;public voidmodityId(eger commodityId) modityId = commodityId;public StringmodityName() returnmodityName;public voidmodityName(String commodityName) modityName = commodityName;public Double getPrice() return this.price;public void setPrice(Double price) this.price = price;2.文件

8、public Double getAgio() return this.agio;public void setAgio(Double agio) this.agio = agio;public Set getConsumes() return this.consumes;public void setConsumes(Set consumes) this.consumes = consumes;3.接口4.实现类代码略。四、商品录入Action.package com.ibeifeng.action;package com.ibeifeng.; import java.util.List;i

9、mport cmodity;publicerface Commoditypublic sic final String PRICE = price;public abstract void save(Commodity transientInstance); public abstract void delete(Commodity persistentInstance); public abstract Commodity findById(java.lang.eger id); public abstract List findByExle(Commodity instance);publ

10、ic abstract List findByProperty(String propertyName, Object value); public abstract ListmodityName(Object commodityName); public abstract List findByPrice(Object price);public abstract List findByAgio(Object agio); public abstract List findAll();public abstract Commodity merge(Commodity detachedInst

11、ance); public abstract void attachDirty(Commodity instance);public abstract void attachClean(Commodity instance);import java.util.List;import comodity;import cmodity;import com.opensymphony.xwork2.ActionSupport;public class CommodityAddActionextendionSupport private String commodityName;private Doub

12、le price; private Double agio; privatesucs; private String msg;private Commoditycommodity;public StringmodityName() return commodityName;public voidmodityName(String commodityName) modityName = commodityName;public Double getPrice() return price;public void setPrice(Double price) this.price = price;

13、public Double getAgio() return agio;public void setAgio(Double agio) this.agio = agio;publicics() return sucs;public void setSucs(sucs) thics = sucs;public String getMsg() return msg;public void setMsg(String msg) this.msg = msg;public Commoditymodity() return commodity;public voidmodity(Commodityco

14、mmodity) modity= commodity;public String execute() throws Exception List commodities = commmodityName(commodityName);/判断用户名是否存在 if(commodities.size() = 0) /如果不存在，则直接保存Commodity commodity = new Commodity();modityName(commodityName); commodity.setPrice(price); commodity.setAgio(agio);commodity.save(co

15、mmodity); sucs = true;msg = 商品录入成功;四、配置文件applicationContext.xmlPROPAGATION_REQUIRED else sucs = false;msg = 该商品名称已经存在，请输入其他商品名称!;return thiCS;struts.xml五、提交处理效果预览：formPanel.getForm().submit( url:commodityAdd.action,waitMsg:请稍等,正在添加!,sucs:function(form, action)Ext.MessageBox.alert(成功,action.result.msg);,failure:function(form, action)Ext.MessageBox.alert(失败,action.result.msg);)commodity添加后清空以前的数据。f
