Flex消息例子(Producer和Consumer)

      不多说，直接上代码，关于Flex消息的信息详见Flex消息服务的文章

 

1.前台Flex代码：

 

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
	xmlns:s="library://ns.adobe.com/flex/spark"
	xmlns:mx="library://ns.adobe.com/flex/mx"
	minWidth="955" minHeight="600"
	creationComplete="application1_creationCompleteHandler(event)">
	
	<fx:Declarations>
		<mx:RemoteObject id="ro" destination="neAlarmProducer"
		endpoint="http://ip:8080/appname/messagebroker/amf"
		showBusyCursor="true"/>
	</fx:Declarations>
	
	<fx:Script>
		<![CDATA[
			import mx.controls.Alert;
			import mx.events.FlexEvent;
			import mx.messaging.ChannelSet;
			import mx.messaging.Consumer;
			import mx.messaging.channels.StreamingAMFChannel;
			import mx.messaging.events.ChannelEvent;
			import mx.messaging.events.ChannelFaultEvent;
			import mx.messaging.events.MessageEvent;
			import mx.messaging.events.MessageFaultEvent;
			import mx.rpc.remoting.RemoteObject;
			
			private var consumer:Consumer=new Consumer();
			
			protected function application1_creationCompleteHandler(event:FlexEvent):void
			{
				var myStreamingAMF:StreamingAMFChannel=new StreamingAMFChannel();
				myStreamingAMF.uri="http://ip:8080/appname/messagebroker/streamingamf";
				var channelSet:ChannelSet=new ChannelSet();
				channelSet.addChannel(myStreamingAMF);
				
				consumer.destination="testDataPush";
				consumer.subtopic="3d";
				
				consumer.channelSet=channelSet;
				consumer.addEventListener(MessageEvent.MESSAGE, messageHandler);
				consumer.addEventListener(ChannelFaultEvent.FAULT, fault);
				consumer.addEventListener(MessageFaultEvent.FAULT, fault2);
				
				consumer.subscribe();//订阅
			}
			
			
			
			private function fault(e:ChannelFaultEvent):void
			{
				trace(e.faultDetail, e.faultString);
			}
			
			private function fault2(e:MessageFaultEvent):void
			{
				trace(e.faultDetail, e.faultString);
			}
			
			private function messageHandler(event:MessageEvent):void
			{
				trace("-----messageHandler-");
				ta.text = ta.text + "获取的告警: " + event.message.body.description + " \n";
			}
			
			private function messageResult(event:MessageEvent):void
			{
				trace("-----messageResult-");				
			}
			
			private function connectHandler(event:ChannelEvent):void
			{
				trace("----connectHandler-");				
			}
			
			private function disconnectHandler(event:ChannelEvent):void
			{
				trace("----disconnectHandler-");				
			}
			
			protected function button1_clickHandler(event:MouseEvent):void
			{
				var ro:RemoteObject=new RemoteObject();
				ro.endpoint="http://ip:8080/appname/messagebroker/streamingamf";
				ro.destination="testPush";
				
				ro.test();
			}
		]]>
	</fx:Script>
	
	<s:Button label="test" click="button1_clickHandler(event)"/>
	<s:TextArea id="ta" x="10" y="42"/>
</s:Application>

 

 

2.message-config.xml中加入如下代码

    <destination id="testDataPush">  
        <properties>  
            <server>  
                <allow-subtopics>true</allow-subtopics>  
                <subtopic-separator>.</subtopic-separator>  
            </server>  
        </properties>  
        <channels>  
            <channel ref="my-polling-amf" />  
            <channel ref="my-streaming-amf" />  
        </channels>  
    </destination>  

 

3.service-config.xml中如果没有此通道，则加入此通道

    <channel-definition id="my-streaming-amf" class="mx.messaging.channels.StreamingAMFChannel">
    	<endpoint url="http://{server.name}:{server.port}/{context.root}/messagebroker/streamingamf" class="flex.messaging.endpoints.StreamingAMFEndpoint"/>
    </channel-definition>

 

4.spring配置文件中加入如下代码：

<!-- 定义 MessageBrokerFactoryBean 工厂 Bean 用于创建 MessageBroker，并为您的 Service Bean 提供绑定服务 -->
<bean id="_messageBroker" class="org.springframework.flex.core.MessageBrokerFactoryBean">  
   	<property name="servicesConfigPath" value="/WEB-INF/flex/services-config.xml" />  
</bean>
	
<!-- 引入 HandlerMapping 通过 MessageBrokerHandlerAdapter 将所有的 Servlet 请求 URL 映射到由 Spring 容器管理的 MessageBroker -->
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">  
	<property name="mappings">  
	       	<props>
	       		<prop key="/*amf*">_messageBroker</prop>
	       		<prop key="*.do">alarmShieldRuleController</prop>
	       	</props>
	</property> 
</bean> 
	
<bean id="defaultMessageTemplate" class="org.springframework.flex.messaging.MessageTemplate" /> 
	
<bean id="testPush" class="TestDataPush"><property name="messageTemplate" ref="defaultMessageTemplate"></property></bean>
	
<bean class="org.springframework.flex.servlet.MessageBrokerHandlerAdapter"/>
	
	
  

5.后台Java代码：

public class TestDataPush {  
    private MessageTemplate messageTemplate;  
    private AsyncMessage asyncMessage;  
  
    public TestDataPush() {  
        super();  
  
        String clientID = UUIDUtils.createUUID();  
        asyncMessage = new AsyncMessage();  
        asyncMessage.setDestination("testDataPush");  
        asyncMessage.setHeader("DSSubtopic", "3d");  
        asyncMessage.setClientId(clientID);  
        asyncMessage.setMessageId(UUIDUtils.createUUID());  
    }  
  
    public void test() {  
        System.out.println("test-------------------");  
        asyncMessage.setTimestamp(System.currentTimeMillis());  
        asyncMessage.setBody("test");  
        messageTemplate.getMessageBroker().routeMessageToService(asyncMessage, null);  
    }  
  
    public MessageTemplate getMessageTemplate() {  
        return messageTemplate;  
    }  
  
    public void setMessageTemplate(MessageTemplate messageTemplate) {  
        this.messageTemplate = messageTemplate;  
    }  
  
}

上传代码要负责，起码自己运行一下，明显错误就上传，是对他人的不负责，同样也是对自己的不负责。

<bean id="testPush" class="TestDataPush"><property name="messageTemplate" ref="defaultMessageTemplate"></property></bean>
这个bean是目的bean，可却缺少<flex:remoting-destination/>
