重要提示：WEB应用服务器要用tomcat6,blazeds和tomcat7有兼容性问题。
1、先创建一个web工程整合Flex，如果不会参考：
http://huanggua12353719.iteye.com/blog/2295720
2、我的工程名为test，在services-config.xml的channels节点内加入
<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"/>
<properties>
<idle-timeout-minutes>0</idle-timeout-minutes>
<max-streaming-clients>10</max-streaming-clients>
<server-to-client-heartbeat-millis>5000</server-to-client-heartbeat-millis>
<user-agent-settings>
<user-agent match-on="MSIE" kickstart-bytes="2048" max-streaming-connections-per-session="1"/>
<user-agent match-on="Firefox" kickstart-bytes="2048" max-streaming-connections-per-session="1"/>
</user-agent-settings>
</properties>
</channel-definition>
3、在messaging-config.xml的service节点内加入
<destination id="tick-data-feed">
<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>
4、在java文件目录src/com包下创建Tick.java
package com;
import java.math.BigDecimal;
import java.util.Date;
public class Tick {
private BigDecimal askPrice;
private BigDecimal bidPrice;
private BigDecimal midPrice;
private Date tickTime;
private String seqno;
public String getSeqno() {
return seqno;
}
public void setSeqno(String seqno) {
this.seqno = seqno;
}
public BigDecimal getAskPrice() {
return askPrice;
}
public void setAskPrice(BigDecimal askPrice) {
this.askPrice = askPrice;
}
public BigDecimal getBidPrice() {
return bidPrice;
}
public void setBidPrice(BigDecimal bidPrice) {
this.bidPrice = bidPrice;
}
public BigDecimal getMidPrice() {
return midPrice;
}
public void setMidPrice(BigDecimal midPrice) {
this.midPrice = midPrice;
}
public Date getTickTime() {
return tickTime;
}
public void setTickTime(Date tickTime) {
this.tickTime = tickTime;
}
}
5、在java文件目录src/com包下创建DaemonMessage.java
package com;
import java.math.BigDecimal;
import java.util.Date;
import flex.messaging.MessageBroker;
import flex.messaging.messages.AsyncMessage;
import flex.messaging.util.UUIDUtils;
public class DaemonMessage
{
private static FeedThread thread;
//开始传递消息
public void startSendMessage(String flags)
{
if (thread == null)
{
thread = new FeedThread();
thread.start();
}
}
//停止消息发布
public void stopSendMessage(String flags)
{
thread.running=false;
thread=null;
}
public static class FeedThread extends Thread
{
public boolean running = true;
public void run()
{
MessageBroker msgBroker = MessageBroker.getMessageBroker(null);
String clientID = UUIDUtils.createUUID();
System.out.println("clientID="+clientID);
int i = 0;
while (running)
{
//异步消息
Tick tick = new Tick();
tick.setAskPrice(new BigDecimal("100"));
tick.setBidPrice(new BigDecimal("100"));
tick.setMidPrice(new BigDecimal("100"));
tick.setTickTime(new Date());
tick.setSeqno(String.valueOf(i));
System.out.println(i);
AsyncMessage msg = new AsyncMessage();
msg.setDestination("tick-data-feed");
msg.setHeader("DSSubtopic", "tick");
msg.setClientId(clientID);
msg.setMessageId(UUIDUtils.createUUID());
msg.setTimestamp(System.currentTimeMillis());
msg.setBody(tick);
msgBroker.routeMessageToService(msg, null);
i++;
try {
Thread.sleep(1000);
} catch (InterruptedException e) {}}}
}
}
6、在flex文件目录flex_src下创建Tick.as
package
{
[RemoteClass(alias="com.Tick")]
[Bindable]
public class Tick
{
public function Tick()
{
}
public var askPrice:Number;
public var bidPrice:Number;
public var midPrice:Number;
public var tickTime:Date;;
public var seqno:String;
}
}
7、在flex主文件test.mxml的内容改成
<?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">
<fx:Script>
<![CDATA[
import mx.controls.Alert;
import mx.messaging.Channel;
import mx.messaging.ChannelSet;
import mx.messaging.Consumer;
import mx.messaging.events.MessageEvent;
import mx.rpc.events.ResultEvent;
private var myConsumer:Consumer = new Consumer();
//直接利用Remote来进行远程的消息调用
//开始订阅消息
protected function rbt_clickHandler(event:MouseEvent):void
{
// TODO Auto-generated method stub
//利用远程调用来触发开始工作
subMessage.startSendMessage("start");
//准备开始订阅消息
myConsumer.destination = "tick-data-feed";
//这里也要与后台的主题名称必须相同 www.it165.net
myConsumer.subtopic = "tick";
myConsumer.channelSet = new ChannelSet(["my-streaming-amf"]);
myConsumer.addEventListener(MessageEvent.MESSAGE, remote_messageHandler);
myConsumer.subscribe();
}
//获取订阅的消息，以文本来显示显示
private function remote_messageHandler(event:MessageEvent):void
{
var tick:Tick = event.message.body as Tick;
demot.text = tick.seqno;
}
//退订该消息
protected function cbr_clickHandler(event:MouseEvent):void
{
subMessage.stopSendMessage("stop");
myConsumer.unsubscribe(false);
}
protected function subMessage_resultHandler(event:ResultEvent):void
{}
]]>
</fx:Script>
<fx:Declarations>
<!--用来启动消息发布 -->
<mx:RemoteObject id="subMessage" destination="RemoteMessage"
result="subMessage_resultHandler(event)"> </mx:RemoteObject>
</fx:Declarations>
<s:TextArea x="445" y="42" width="257" id="demot"/>
<s:Button x="445" y="210" label="订阅消息Remote" id="rbt" click="rbt_clickHandler(event)"/>
<s:Button x="597" y="207" label="退订消息R" id="cbr" click="cbr_clickHandler(event)"/>
</s:Application>
8、在remoting-config.xml文件service节点中加入
<destination id="RemoteMessage">
<properties>
<source>com.DaemonMessage</source>
</properties>
</destination>
9、配置完之后的目录如下：
10、如果bin-debug目录下没有生成相应的html文件。右键工程-》属性-》Flex编译器-》生成HTML包装器文件（H）,去掉勾选，点应用，再勾选上就应用 。testmxml相对应的html文件就出现了。
11、启动工程，访问http://localhost:8080/test/test/test.html
如果出现404错误，打开test.mxml随便编辑（不能修改代码，可以在末尾添加一个空格，删除一个空格），目的是让工程重新生成对应的html文件，保存。再访问。如果成功出现
12、点击订阅消息Remote空白框里会出现1、2、3、4 ...不停的在变，点击退订消息R,数字不再变，部署成功。
13、如果这样还不行，可以留言，大家讨论一下。
