BlazeDs + Spring 整合

在Flex + BlazeDS + java 整合完成的基础上

1. 修改web.xml配置文件。原来是通过blazeds拦截，现在改成用spring 拦截。

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"><web-app>    <display-name>BlazeDS</display-name>    <description>BlazeDS Application</description>    <!-- Http Flex Session attribute and binding listener support -->    <listener>        <listener-class>flex.messaging.HttpFlexSession</listener-class>    </listener>     <!-- 定义 spring flex 集成的配置，使用单独的配置文件。        不使用在一个applicatonContext.xml中import springFlex.xml的方法         spring flex 一定要用DispatcherServlet 方法。不能用ContextLoaderListener -->    <servlet>        <servlet-name>MessagebrokerServlet</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>/WEB-INF/applicationContext.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>        <!-- Map /spring/* requests to the DispatcherServlet -->    <servlet-mapping>        <servlet-name>MessagebrokerServlet</servlet-name>        <url-pattern>/messagebroker/*</url-pattern>    </servlet-mapping>    <!-- 定义 spring flex 集成的配置  结束-->    <welcome-file-list>        <welcome-file>index.html</welcome-file>        <welcome-file>index.htm</welcome-file>    </welcome-file-list>    <!-- for WebSphere deployment, please uncomment -->    <!--    <resource-ref>        <description>Flex Messaging WorkManager</description>        <res-ref-name>wm/MessagingWorkManager</res-ref-name>        <res-type>com.ibm.websphere.asynchbeans.WorkManager</res-type>        <res-auth>Container</res-auth>        <res-sharing-scope>Shareable</res-sharing-scope>    </resource-ref>    --></web-app>

2. 添加Spring配置文件：applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:flex="http://www.springframework.org/schema/flex" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-2.5.xsdhttp://www.springframework.org/schema/flex http://www.springframework.org/schema/flex/spring-flex-1.5.xsd"><!-- spring 配置文件来定义 --><flex:message-broker><flex:message-service default-channels="my-amf, my-polling-amf" /></flex:message-broker><bean id="hello" class="test.HelloWord"><flex:remoting-destination/></bean></beans>

3.Flex客户端调用

<?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"   creationComplete="application1_creationCompleteHandler(event)"><fx:Script><![CDATA[import mx.controls.Alert;import mx.events.FlexEvent;import mx.rpc.events.FaultEvent;import mx.rpc.events.ResultEvent;protected function application1_creationCompleteHandler(event:FlexEvent):void{ro.getName("XOXOXO");}protected function ro_resultHandler(event:ResultEvent):void{Alert.show(event.result as String);}protected function ro_faultHandler(event:FaultEvent):void{Alert.show(event.fault.faultString);}]]></fx:Script><fx:Declarations><s:RemoteObject id="ro"result="ro_resultHandler(event)"fault="ro_faultHandler(event)"destination="hello"/></fx:Declarations></s:Application>

* 启动服务器，开始运行，弹出 发送失败。原因是因为没有定义endpoint的，但是有不希望在Flex客户端中硬编码写入endpoint。怎么解决呢？

1. 先在Flex项目中添加一个编译参数：-services "D:\carsonsoft\commhome\webapps\DLUvsServer\WEB-INF\flex\services-config.xml"

2. 在services-config.xml中添加默认的通道和端点：

<services><service-include file-path="remoting-config.xml" /><service-include file-path="proxy-config.xml" /><service-include file-path="messaging-config.xml" /><default-channels><channel ref="my-amf" /></default-channels></services>

Spring + BlazeDS 整合完毕。很简单吧。不过我整合的时候发了将近一天。走了不少弯路呀。
