Flex&iBatis&Hibernate&Spring—师徒奶茶系统V1总结

来源：互联网发布：微商必备软件编辑：程序博客网时间：2024/05/02 03:16

昨晚只睡了两个小时来改进这个属于我们“下午茶”师徒群的同学们。主要是用Flex做前端，Java做后台。其实整个系统搭建起来很容易，因为Flex&Java应该说是我最熟悉的吧。为了快速和友好的交互，当然还是用这个。不过这次比较傻的是，前几天实现的用户列表的增删查改是用iBatis，主要原因是想基于以前一个简单的测试项目，前面几篇博文中有详细的介绍。可是，昨晚抽风又想用Hibernate了。这样就是说我需要两个信道“AMF”和“RTMP”。所以就会出现一些问题。不过还好，最后发现问题应该是AMF信道的配置。Channel当时临时写在了客户端代码里面。其实应该写在一个properties或者xml文件中去读取的。好了吧。废话不多说。上代码。首先是客户端代码。主要的AS:

 <mx:Script>        <![CDATA[        import mx.controls.DateField;        import control.print.FormPrintView;        import mx.managers.PopUpManager;        import vo.User;        import mx.collections.ArrayCollection;        import mx.rpc.events.ResultEvent;        import mx.rpc.events.FaultEvent;        import mx.utils.ArrayUtil;            import mx.controls.Alert;            import control.showGoods;            import mx.printing.PrintDataGrid;import mx.printing.FlexPrintJob;import control.*;            [Bindable]            private var users:ArrayCollection;            [Bindable]            private var myUser:User=new User();                        private function selectedDGrid():void{            userName.text=userdg.selectedItem.username;            password.text=userdg.selectedItem.password;            company.text=userdg.selectedItem.company;            note.text=userdg.selectedItem.note;            }                        private function getAllUsers_resultHandler(event:ResultEvent):void{                users = event.result as ArrayCollection;            }                        private function getUserByCompanyName_resultHandler(event:ResultEvent):void            {                users = event.result as ArrayCollection;            }                        private function getUsersByQuery_resultHandler(event:ResultEvent):void            {                users = event.result as ArrayCollection;                            }                        private function insertUser():void{             myUser.username=userName.text;              myUser.password=password.text;              myUser.company=company.text;              myUser.note=note.text;              user.insertUser(myUser);              Alert.show("save a user named : "+userName.text,"SAVE!");            }                        private function clearTexts():void{            userName.text='';            password.text='';            company.text='';            note.text='';            }                                    private function updateUser():void{                 var uu:User=userdg.selectedItem as User;             uu.username=userName.text;              uu.password=password.text;              uu.company=company.text;              uu.note=note.text;              user.updateUser(uu);              Alert.show("update a user!","UPDATE!");            }                        private function deleteUser():void{             user.deleteUser(userdg.selectedItem.id);             Alert.show("delete a user named : "+userdg.selectedItem.username,"DELETE!");            }                        private function faultHandler(event:FaultEvent):void            {                Alert.show(event.fault.faultString, "Error");            }                        public function doPrint():void {           var printJob:FlexPrintJob = new FlexPrintJob();           if (printJob.start()) {               var thePrintView:FormPrintView= new FormPrintView();               Application.application.addChild(thePrintView);               thePrintView.width=printJob.pageWidth;               thePrintView.height=printJob.pageHeight;               thePrintView.myDataGrid.dataProvider=userdg.dataProvider;               thePrintView.showPage("single");               if(!thePrintView.myDataGrid.validNextPage)               {                   printJob.addObject(thePrintView);               }               else               {                   thePrintView.showPage("first");                   printJob.addObject(thePrintView);                   thePrintView.pageNumber++;                   while(true)                   {                       thePrintView.myDataGrid.nextPage();                       thePrintView.showPage("last");                       if(!thePrintView.myDataGrid.validNextPage)                       {                           printJob.addObject(thePrintView);                           break;                       }                       else                       {                           thePrintView.showPage("middle");                           printJob.addObject(thePrintView);                           thePrintView.pageNumber++;                       }                   }               }               Application.application.removeChild(thePrintView);           }           printJob.send();       }                               ]]>    </mx:Script>

AS一如往常，木有什么特别。下面是远程调用的RemoteObject 调用实现：

 <mx:RemoteObject  id="user" destination="userservice"  channelSet="{channelSet}" fault="faultHandler(event)" source="com.qiyun.spritis.pojo.User">        <mx:method name="getAllUsers" result="getAllUsers_resultHandler(event)"/>        <mx:method name="getUserByCompanyName" result="getUserByCompanyName_resultHandler(event)">            <mx:arguments>                <arg1> {companies.selectedItem.data}</arg1>            </mx:arguments>        </mx:method>        <mx:method name="updateUser" >        <mx:arguments>        <arg1>        {myUser}        </arg1>        </mx:arguments>         </mx:method>        <mx:method name="insertUser">        <mx:arguments>        <arg1>        {myUser}        </arg1>        </mx:arguments>         </mx:method>        <mx:method name="deleteUser" >        <mx:arguments>        <arg1>        {userdg.selectedItem.id}        </arg1>        </mx:arguments>         </mx:method>            </mx:RemoteObject>

后面就是一些界面代码，没有太大参考价值，这里把图贴出来吧。

以上是ibatis和Spring的部分。下面是Hibernate。用了LCDS的data-management.重要的客户端代码是这一行：

<mx:DataService id="hib_good" destination="hibernate_goods" autoCommit="true" />

另外，关键的配置在客户端的data-management-config.xml里面：

<?xml version="1.0" encoding="UTF-8"?><service id="data-service"     class="flex.data.DataService">    <adapters>        <adapter-definition id="actionscript" class="flex.data.adapters.ASObjectAdapter" default="true"/>        <adapter-definition id="java-dao" class="flex.data.adapters.JavaAdapter"/>    </adapters><default-channels>        <channel ref="my-rtmp"/>    </default-channels>         <destination id="hibernate_goods"><adapter ref="java-dao" /><properties><use-transactions>true</use-transactions><source>flex.data.assemblers.HibernateAssembler</source><scope>application</scope><metadata><identity property="id" /></metadata><network><paging enabled="false" pageSize="10" /><throttle-inbound policy="ERROR" max-frequency="500" /></network><server><fill-method><name>fill</name><params>java.util.List</params></fill-method><hibernate-entity>com.qiyun.spritis.pojo.Goods</hibernate-entity><update-conflict-mode>property</update-conflict-mode><delete-conflict-mode>object</delete-conflict-mode><fill-configuration><use-query-cache>false</use-query-cache><allow-hql-queries>true</allow-hql-queries></fill-configuration></server></properties></destination></service>

hibernate部分列表的页面图片如下：

到这里就差不多了。Java代码很简单，没有复杂的逻辑。这个就是5个小时做出来的师徒奶茶订阅系统。以后和徒儿们一起喝奶茶就可以用这个了。Flex的魅力是无穷的，不过最近在学习JS和CSS还有些前端的东西。后续一点点分享出来吧。
