Flex 与 Spring 集成
参考文档是 Spring BlazeDS Integration Reference Guide。spring已经提供了与flex的集成的支持，主要的jar包下载地址：http://www.springsource.com/download/community?project=Spring%20BlazeDS%20Integration
Flex与Spring集成的核心思想就是让Spring来管理 MessageBroker。如何集成？可以总结为三步。
1、首先，修改 web.xml文件，将之前配置的 MessageBrokerServlet 去掉改成spring的，
<servlet> <servlet-name>Spring MVC Dispatcher Servlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/config/web-application-config.xml </param-value> </init-param> <load-on-startup>1</load-on-startup></servlet><servlet-mapping> <servlet-name>Spring MVC Dispatcher Servlet</servlet-name> <url-pattern>/messagebroker/*</url-pattern></servlet-mapping>
2，新建文件 web-application-config.xml
<?xml version="1.0" encoding="GB2312" ?><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/flexhttp://www.springframework.org/schema/flex/spring-flex-1.0.xsd"><!-- Bootstraps and exposes the BlazeDS MessageBroker simplest form --><flex:message-broker id="_messageBroker" services-config-path="/WEB-INF/flex/services-config.xml"> <flex:mapping pattern="/messagebroker/*" /> <flex:exception-translator ref="myExceptionTranslator" /></flex:message-broker><!--上面配置是一种简单配置，另外一种更简单配置为：<flex:message-broker/>还有一种配置为：<bean id="mySpringManagedMessageBroker" class="org.springframework.flex.core.MessageBrokerFactoryBean"> <property name="servicesConfigPath" value="classpath*:flex/services-config.xml" /></bean>--><!-- Maps request paths at /* to the BlazeDS MessageBroker --><bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <value> /*=_messageBroker </value> </property></bean><!-- 下面这个Adapter似乎不用配置，因为我注释后照样可以使用 --><!--Dispatches requests mapped to a MessageBroker <bean class="org.springframework.flex.servlet.MessageBrokerHandlerAdapter" />--></beans>
3，写remoting-config.xml 文件：
<?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></service>
到目前为止，flex已经跟spring集成到一起了。
4、将spring的bean导出为flex的Destination。我们要在web-application-config.xml文件中增加。
有三种方式：
第一种：
<bean id="productService" class="flex.samples.product.ProductServiceImpl" /><flex:remoting-destination ref="productService" />
第二种：
<bean id="productService" class="flex.samples.product.ProductServiceImpl" > <flex:remoting-destination /></bean>
第三种：
<bean id="product" class="org.springframework.flex.remoting.RemotingDestinationExporter"> <property name="messageBroker" ref="_messageBroker"/> <property name="service" ref="productService"/> <property name="serviceId" value="productService"/> <property name="includeMethods" value="read, update"/> <property name="excludeMethods" value="create, delete"/> <property name="channels" value="my-amf, my-secure-amf"/></bean>
