AS一如往常，木有什麼特別。下面是遠程調用的RemoteObject 調用實現：
<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>
後面就是一些界面代碼，沒有太大參考價值，這裏把圖貼出來吧。
以上是ibatis和Spring的部分。下面是Hibernate。用了LCDS的data-management.重要的客戶端代碼是這一行：
<mx:DataService id="hib_good" destination="hibernate_goods" autoCommit="true" />
另外，關鍵的配置在客戶端的data-management-config.xml裏面：
<?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部分列表的頁面圖片如下：
到這裏就差不多了。Java代碼很簡單，沒有複雜的邏輯。這個就是5個小時做出來的師徒奶茶訂閱系統。以後和徒兒們一起喝奶茶就可以用這個了。Flex的魅力是無窮的，不過最近在學習JS和CSS還有些前端的東西。後續一點點分享出來吧。
