blazeDS集成spring的remote访问

上一篇我只是简单实用blazeds创建了一个实例，大多数开发中，都是结合spring的spring BlazeDS Integration来进行开发。首先你要去官方网站上下载个jar包，我这里提供了我项目中的所有jar包的打包供你测试本示例实用，当然里面有很多多余jar包。项目中所有jar包地址（如地址问题，请联系博主）。
集成开始，当然你要创建一个web项目，然后配置web.xml如下，这个就多添加了个spring的servlet，来代替"flex.messaging.MessageBrokerServlet"这个servlet。
1 <?xml version="1.0" encoding="UTF-8"?> 2 <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> 3 <web-app> 4 5 <display-name>BlazeDS Spring Integration Application</display-name> 6 <description>BlazeDS Spring Integration Application</description> 7 8 <!-- Http Flex Session attribute and binding listener support --> 9 <listener> 10 <listener-class>flex.messaging.HttpFlexSession</listener-class> 11 </listener> 12 13 <listener> 14 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 15 </listener> 16 17 <!-- Spring Dispatcher Servlet --> 18 <servlet> 19 <servlet-name>flex</servlet-name> 20 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 21 <init-param> 22 <param-name>contextConfigLocation</param-name> 23 <!-- 就是你项目中的‘applicationContext.xml’，作用一样 --> 24 <param-value>/WEB-INF/flex-servlet.xml</param-value> 25 </init-param> 26 <load-on-startup>1</load-on-startup> 27 </servlet> 28 29 <servlet-mapping> 30 <servlet-name>flex</servlet-name> 31 <url-pattern>/messagebroker/*</url-pattern> 32 </servlet-mapping> 33 34 <welcome-file-list> 35 <welcome-file>index.html</welcome-file> 36 <welcome-file>index.jsp</welcome-file> 37 </welcome-file-list> 38 39 40 </web-app>
然后修改/WEB-INF/flex-servlet.xml这个配置文件，为了使用 Spring BlazeDS Integration 的 tag，增加命名空间flex。我还是文件内容全部贴上，说明写到注释里面吧。
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:flex="http://www.springframework.org/schema/flex" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 6 xsi:schemaLocation=" 7 http://www.springframework.org/schema/beans 8 http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 9 http://www.springframework.org/schema/flex 10 http://www.springframework.org/schema/flex/spring-flex-1.5.xsd 11 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 12 13 <context:component-scan base-package="com.bing"> 14 </context:component-scan> 15 <!-- 请求路由给 MessageBroker --> 16 <flex:message-broker> 17 <flex:message-service default-channels="my-streaming-amf,my-longpolling-amf,my-polling-amf,my-amf" /> 18 </flex:message-broker> 19 <!-- <flex:message-broker /> --> 20 <!-- 定义 Bean，并用 remoting-destination tag 把它暴露给 Flex，因为我用了annotation的方式，所以下面的注解掉了 --> 21 <!-- <bean id="myService" class="com.bing.service.MyServiceImpl" /> 22 <flex:remoting-destination ref="myService" /> --> 23 </beans>
然后修改/WEB-INF/flex/services-config.xml这个配置文件,默认的话这个文件夹是有四个文件的（services-config.xml、remoting-config.xml、proxy-config.xml、messaging-config.xml），集成spring后，其他三个都没有什么用了，我删掉了。

基本的配置差不多都好了，当然你得加入jar包。下面就开始编写代码部分。代码是网上拷贝的，自己懒得写了。
创建实体类，模拟用，其实你可以这返回一句话。
1 package com.bing.vo; 2 3 public class MyEntity { 4 private String frstName; 5 private String lastName; 6 private String emailAddress; 7 8 public String getFirstName() { 9 return frstName; 10 } 11 12 public void setFirstName(String frstName) { 13 this.frstName = frstName; 14 } 15 16 public String getLastName() { 17 return lastName; 18 } 19 20 public void setLastName(String lastName) { 21 this.lastName = lastName; 22 } 23 24 public String getEmailAddress() { 25 return emailAddress; 26 } 27 28 public void setEmailAddress(String emailAddress) { 29 this.emailAddress = emailAddress; 30 } 31 }
创建service接口类及其实现类。
package com.bing.service; public interface MyService { String getMyEntities(); }
1 package com.bing.service; 2 3 import java.util.ArrayList; 4 import java.util.List; 5 6 import org.springframework.flex.remoting.RemotingDestination; 7 import org.springframework.flex.remoting.RemotingInclude; 8 import org.springframework.stereotype.Component; 9 10 import com.bing.vo.MyEntity; 11 import com.thoughtworks.xstream.XStream; 12 @Component("myService") 13 @RemotingDestination(channels = { "my-amf" }) 14 public class MyServiceImpl implements MyService { 15 16 @Override 17 @RemotingInclude 18 public String getMyEntities() { 19 List<MyEntity> list = new ArrayList<MyEntity>(); 20 MyEntity entity = new MyEntity(); 21 entity.setFirstName("Hello"); 22 entity.setLastName("World"); 23 entity.setEmailAddress("hello@world.com"); 24 list.add(entity); 25 MyEntity entity2 = new MyEntity(); 26 entity2.setFirstName("你好"); 27 entity2.setLastName("jone"); 28 entity2.setEmailAddress("hello@space.com"); 29 list.add(entity2); 30 XStream x=new XStream(); 31 x.alias("vo", MyEntity.class); 32 System.out.println(x.toXML(list)); 33 return x.toXML(list); 34 } 35 36 }
后台代码基本搞定，就是返回一个xml的对象字符串。中间用了一下Xstream这个jar工具。发布一下项目到tomcat下，然后启动看看……
前台就简单了，打开flash builder，创建一个flash项目，和上一篇例子基本一样。不过这里我把输出的路径改到tomcat下了。
然后编写成徐代码：进行测试
1 <?xml version="1.0" encoding="utf-8"?> 2 <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 3 xmlns:s="library://ns.adobe.com/flex/spark" 4 xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"> 5 <fx:Script> 6 <![CDATA[ 7 import mx.controls.Alert; 8 import mx.messaging.ChannelSet; 9 import mx.messaging.channels.StreamingAMFChannel; 10 import mx.messaging.messages.IMessage; 11 import mx.rpc.events.FaultEvent; 12 import mx.rpc.events.ResultEvent; 13 14 15 private function dotest():void { 16 //var myStreamingAMF:StreamingAMFChannel = new StreamingAMFChannel("my-amf", "/blazedsfirst/messagebroker/amf"); 17 18 /* var myStreamingAMF:StreamingAMFChannel=new StreamingAMFChannel(); 19 var channelSet:ChannelSet=new ChannelSet(); 20 channelSet.addChannel(myStreamingAMF); 21 remoteObject.channelSet=channelSet;*/ 22 remoteObject.getMyEntities(); 23 } 24 // Handle the recevied message. 25 private function resultHandler(event:ResultEvent):void { 26 Alert.show(event.result.toString()); 27 } 28 29 // Handle a message fault. 30 private function faultHandler(event:FaultEvent):void { 31 Alert.show("Received fault: " + event.fault); 32 } 33 34 ]]> 35 </fx:Script> 36 <fx:Declarations> 37 <s:RemoteObject id="remoteObject" 38 destination="myService" 39 result="resultHandler(event);" 40 fault="faultHandler(event);"/> 41 42 43 </fx:Declarations> 44 45 <s:layout> 46 <s:VerticalLayout gap="0" horizontalAlign="center" paddingTop="50"/> 47 </s:layout> 48 <s:Label text="测试spring集成remote"/> 49 <s:Button label="Send" click="dotest();"/> 50 51 52 </s:Application>
直接运行进行测试，弹出结果如下：
<list> <vo> <frstName>Hello</frstName> <lastName>World</lastName> <emailAddress>hello@world.com</emailAddress> </vo> <vo> <frstName>你好</frstName> <lastName>Space</lastName> <emailAddress>hello@space.com</emailAddress> </vo> </list>
下一篇我将介绍一下，push推送技术,如何利用spring和blazeds实现。
