spring+blazeds集成

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：

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，
Java代码
<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
Java代码
<?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：
Java代码
<?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：

Java代码
<bean id="productService" class="flex.samples.product.ProductServiceImpl" />  
<flex:remoting-destination ref="productService" /> 


第二种：

Java代码
<bean id="productService" class="flex.samples.product.ProductServiceImpl" >  
     <flex:remoting-destination />  
</bean> 

第三种：

Java代码
<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>
