Flex与Java中的Object交互

作者：shehun1 编辑：王玉圆 2011-08-18 00:05 来源：专家�

　修改Flex主文件：BlazObject.mxml，在其中调用java类，代码如下：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" minWidth="955" minHeight="600">

    <mx:Script>
        <![CDATA[
            import com.flex.model.SpeakUser;

            import mx.controls.Alert;
            import mx.rpc.events.ResultEvent;

            public function remotingHelloJavaFlex():void
            {

                var user:SpeakUser = new SpeakUser();

                user.userName = nameInputTxt.text;
                user.userMail = txtUserMail.text;
                user.userPwd = txtPwd.text;
                user.userTel = txtTel.text;


                someOneCome.speak(user);
                someOneCome.addEventListener(ResultEvent.RESULT,getRoHelloRes);
            }

            private function getRoHelloRes(e:ResultEvent):void{
                Alert.show(e.result.toString());
            }

            private function failed():void{
                Alert.show("cuowu");
            }
        ]]>
    </mx:Script>

    <mx:Button label="JAVA Object + FLEX 通信" click="remotingHelloJavaFlex();" x="142" y="234"
               fontSize="12" width="209"/>
    <mx:Label text="姓名" x="121" y="55" fontSize="15"/>
    <mx:TextInput id="nameInputTxt" x="170" y="55"/>
    <mx:Label x="121" y="103" fontSize="15" text="密码："/>
    <mx:TextInput id = "txtPwd" x="170" y="106"/>
    <mx:Label x="121" y="145" fontSize="15" text="电话："/>
    <mx:Label x="121" y="187" fontSize="15" text="邮箱："/>
    <mx:TextInput id="txtTel" x="170" y="148"/>
    <mx:TextInput id="txtUserMail" x="170" y="190"/>

    <mx:RemoteObject destination="someOneComeDes" id="someOneCome" endpoint="/BlazDSObject/messagebroker/amf" fault="failed()" />

</mx:Application>

在这里，Flex是通过AMF协议与Java对象进行交互的，其中endpoint定义了影射文件的消息协议，这个文件来自/WEB-INF/flex/services-config.xml中，影射对象的位置是通过remoting-service.xml影射的代码如下：

<channel-definition id="my-secure-amf" class="mx.messaging.channels.SecureAMFChannel">
            <endpoint url="https://{server.name}:{server.port}/{context.root}/messagebroker/amfsecure" class="flex.messaging.endpoints.SecureAMFEndpoint"/>
            <properties>
                <add-no-cache-headers>false</add-no-cache-headers>
            </properties>
        </channel-definition>

remoting-service.xml

<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service"
    class="flex.messaging.services.RemotingService">

    <adapters>
        <adapter-definition id="java-object" class="flex.messaging.services.remoting.adapters.JavaAdapter" default="true"/>
    </adapters>

    <default-channels>
        <channel ref="my-amf"/>
    </default-channels>

    <destination id="someOneComeDes">
        <properties>
            <source>
                com.cx.action.IntroduceOneself
            </source>
        </properties>
    </destination>

</service>
