Java Server Push To Flex (ServerPush)

来源：互联网发布：java 线程 static 编辑：程序博客网时间：2024/06/03 06:12

在网上找了许多的Flex与java 通信做ServerPush 的例子，发现有许多不正确，今天就做了一小程序。希望对大家有用

1. Product 类

package com.east.flex.serverpush.entity;/** * 产品类 * @author East(张栋芳) * * 2010-6-12 */public class Product {private String month;private int profit;private int expenses;private int amount;public String getMonth() {return month;}public void setMonth(String month) {this.month = month;}public int getProfit() {return profit;}public void setProfit(int profit) {this.profit = profit;}public int getExpenses() {return expenses;}public void setExpenses(int expenses) {this.expenses = expenses;}public int getAmount() {return amount;}public void setAmount(int amount) {this.amount = amount;}}

2. ServerPushThread

package com.east.flex.serverpush.chart;import java.util.ArrayList;import java.util.List;import java.util.Random;import com.east.flex.serverpush.entity.Product;import flex.messaging.MessageBroker;import flex.messaging.messages.AsyncMessage;import flex.messaging.util.UUIDUtils;/** * 构造数据后台线程 * * @author East(张栋芳) * * 2010-6-13 */public class ServerPushThread extends Thread {public boolean running = true;@Overridepublic void run() {MessageBroker msgBroker = MessageBroker.getMessageBroker(null);String clientId = UUIDUtils.createUUID();while (running) {/* ============================== */// TODO do someing/* ============================== */List<Product> productList = getProductList();AsyncMessage msg = new AsyncMessage();msg.setDestination("serverpush");msg.setClientId(clientId);msg.setMessageId(UUIDUtils.createUUID());msg.setTimestamp(System.currentTimeMillis());/* 设置消息信息，发布到客户端去 */msg.setBody(productList);msgBroker.routeMessageToService(msg, null);try {Thread.sleep(10000);} catch (InterruptedException se) {}}}/** * 模拟数据信息 * * @return */public List<Product> getProductList() {List<Product> productList = new ArrayList<Product>();for (int i = 1; i < 7; i++) {Product p = new Product();Random random = new Random();//String month = i == 1 ? "Jan" : i == 2 ? "Fre" : "May";String month = i == 1 ? "January" : i == 2 ? "February" : i==3 ? "February":i==4 ? "April":i==5?"May":"June";p.setMonth(month);p.setProfit(random.nextInt(1000));p.setExpenses(random.nextInt(500));p.setAmount(random.nextInt(300));productList.add(p);}return productList;}}

3. ServerPushServer

package com.east.flex.serverpush.chart;/** * 服务发布类 * * @author East(张栋芳) * * 2010-6-13 */public class ServerPushServer {ServerPushThread serverPushThread;/** * 启动线程 */public void start() {serverPushThread = new ServerPushThread();serverPushThread.start();System.out.println("Server is start....");}/** * 停止线程 */public void stop() {serverPushThread.stop();System.out.println("Server is stop....");}}

4. messaging-config.xml

<?xml version="1.0" encoding="UTF-8"?><service id="message-service" class="flex.messaging.services.MessageService"> <adapters> <adapter-definition id="actionscript" class="flex.messaging.services.messaging.adapters.ActionScriptAdapter" default="true" />  </adapters> <default-channels> <channel ref="my-polling-amf"/> </default-channels> <default-channels><channel ref="my-streaming-amf"/><channel ref="my-polling-amf"/> </default-channels> <destination id="serverpush" channels="my-polling-amf" /> </service>

5. remoting-config.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="createProduct"><properties><source>com.east.flex.serverpush.CreateProduct</source></properties></destination><destination id="serverpushserver"><properties><source>com.east.flex.serverpush.chart.ServerPushServer</source></properties></destination></service>

6. Product.as

package com.east.flex.entity{import mx.rpc.remoting.RemoteObject;[RemoteClass(alias="com.east.flex.serverpush.entity.Product")]public class Product{public var month:String;public var profit:int;public var expenses:int;public var amount:int;public function Product(){}}}

7.ServerPushChart.mxml

<?xml version="1.0"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"><mx:Script>import com.east.flex.entity.Product</mx:Script> <mx:Script>  </mx:Script><mx:Consumer id="consumer" destination="serverpush" message="messageHandler(event)"/><mx:RemoteObject id="server" destination="serverpushserver" result="remoteServerCallback(event)"/>  <mx:SolidColor id="sc1" color="blue" alpha=".3"/> <mx:SolidColor id="sc2" color="red" alpha=".3"/> <mx:SolidColor id="sc3" color="green" alpha=".3"/>  <mx:Stroke id = "s1" color="blue" weight="2"/> <mx:Stroke id = "s2" color="red" weight="2"/> <mx:Stroke id = "s3" color="green" weight="2"/> <mx:Panel title="LineChart and AreaChart Controls Example" height="100%" width="100%" layout="absolute"> <mx:LineChart id="linechart" height="100%" width="1030" paddingLeft="5" paddingRight="5" showDataTips="true" x="0" y="0"> <mx:horizontalAxis> <mx:CategoryAxis categoryField="month"/> </mx:horizontalAxis> <mx:series> <mx:LineSeries yField="profit" form="curve" displayName="profit" lineStroke="{s1}"/> <mx:LineSeries yField="expenses" form="curve" displayName="expenses" lineStroke="{s2}"/> <mx:LineSeries yField="amount" form="curve" displayName="amount" lineStroke="{s3}"/> </mx:series> </mx:LineChart> <mx:Legend dataProvider="{linechart}" x="1038" y="0" width="107"/> <mx:Button id="autoOk" label="AutoRefresh" x="1038" y="87" width="107" click="consumer.subscribe()" enabled="{!consumer.subscribed}"/> <mx:Button id="cancel" x="1038" y="135" width="107" label="Cancel Auto " click="consumer.unsubscribe()" enabled="{consumer.subscribed}"/> <mx:Button id="cancel0" x="1038" y="187" width="107" label="Start Server" click="startServer(event)"/> <mx:Button id="cancel1" x="1038" y="237" width="107" label="Stop Server" click="stopServer(event)"/> </mx:Panel></mx:Application>
