本文主要学习Flex跟spring如何集成。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

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/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/flex
http://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>
