Flex 的spring+BlazeDS整合注意事项

弄了一天,终于把spring+BlazeDS整合好了。
首先阅读了：spring的官方文档【Spring BlazeDS Integration Reference Guide】。
http://static.springsource.org/spring-flex/docs/1.0.x/reference/html/index.html
好多页，慢慢看。
但是按照整个文档，一步一步走下来，还是不行，经过多次尝试，终于可以了，现在把心得写下来，仅供参考。
本来我的j2ee工程是 extjs+spring2.56+hibernate3.3的，因为需要就整合flex，这时就需要BlazeDS了，
需要下：org.springframework.flex-1.0.0.RELEASE.jar。
还有flex需要 /WEB-INF/flex/整个目录。

注意点：
1,写spring blazeds配置文件:spring-context-80-BlazeDS.xml
内容如下：

<?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/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 -->
	<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <value>
                /messagebroker/*=_messageBroker
            </value>
        </property>
    </bean>

	<!-- Dispatches requests mapped to a MessageBroker -->
	<bean class="org.springframework.flex.servlet.MessageBrokerHandlerAdapter"/>

	<!-- Bootstraps and exposes the BlazeDS MessageBroker -->
	<bean id="_messageBroker" class="org.springframework.flex.core.MessageBrokerFactoryBean" /><bean id="flex_base_service" class="com.ria.conn.amf.service.impl.FlexBaseService"/>
<bean id="flex_base_service_000" class="org.springframework.flex.remoting.RemotingDestinationExporter">
	<property name="messageBroker" ref="_messageBroker"/>
<property name="service" ref="flex_base_service"/>
	
	<property name="channels">   
		<list>
			<value>my-amf</value>
			<value>my-secure-amf</value>
			<value>my-polling-amf</value>
			<value>my-streaming-amf</value>
		</list>   
	</property>
</bean>
</beans>

2,web.xml里面 修改url的拦截器为spring.

	<servlet> 
        <servlet-name>SpringMVCDispatcherServlet</servlet-name> 
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
        <init-param> 
            <param-name>contextConfigLocation</param-name> 
            <param-value>
                   classpath:/applicationContext*.xml 
                classpath*:/spring-context-80-BlazeDS.xml
                /WEB-INF/applicationContext*.xml
            </param-value> 
        </init-param> 
        <load-on-startup>2</load-on-startup> 
    </servlet> 
	<!-- Map all /messagbroker requests to the DispatcherServlet for handling -->
	<servlet-mapping>
		<servlet-name>SpringMVCDispatcherServlet</servlet-name>
		<url-pattern>/spring/*</url-pattern>
	</servlet-mapping>

3,修改/WEB-INF/flex/services-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<services-config>
	<!-- 注册SpringFactory工厂 -->
	<factories> 
		<factory id="my-flexfactory4spring" class="com.ria.common.flex.spring.FlexSpringFactory"/> 
	</factories>
    <services>
        <service-include file-path="remoting-config.xml" />
        <service-include file-path="proxy-config.xml" />
        <service-include file-path="messaging-config.xml" />
    	<!-- 下面这个设置很重要，是应用的(全局的)参数，否则spring+blazeDS整合没法用.    	Application level default channels. Application level default channels are 
    	necessary when a dynamic destination is being used by a service component
    	and no ChannelSet has been defined for the service component. In that case,
    	application level default channels will be used to contact the destination.
        -->   
        <default-channels>
           <channel ref="my-amf"/>
        </default-channels>
    </services>

    <security>
        <login-command class="flex.messaging.security.TomcatLoginCommand" server="Tomcat"/>
        <!-- Uncomment the correct app server
        <login-command class="flex.messaging.security.TomcatLoginCommand" server="JBoss">
		<login-command class="flex.messaging.security.JRunLoginCommand" server="JRun"/>        
        <login-command class="flex.messaging.security.WeblogicLoginCommand" server="Weblogic"/>
        <login-command class="flex.messaging.security.WebSphereLoginCommand" server="WebSphere"/>
        -->

        <!-- 
        <security-constraint id="basic-read-access">
            <auth-method>Basic</auth-method>
            <roles>
                <role>guests</role>
                <role>accountants</role>
                <role>employees</role>
                <role>managers</role>
            </roles>
        </security-constraint>
         -->
    </security>

    <channels>
		<!-- 以下的 spring_messagebroker 串正好是 web.xml里面的拦截URL串,以前是messagebroker,被 blazeds servlet拦截,现在是被spring+BlazeDS servlet拦截 -->
        <channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel">
            <!--endpoint url="http://{server.name}:{server.port}/{context.root}/messagebroker/amf" class="flex.messaging.endpoints.AMFEndpoint"/-->

        </channel-definition>

    </channels>

    <logging>
        <target class="flex.messaging.log.ConsoleTarget" level="Debug">
            <properties>
                <prefix>[BlazeDS] </prefix>

    <system>
        <redeploy>
            <enabled>false</enabled>
            <!--

            <watch-file>{context.root}/WEB-INF/flex/services-config.xml</watch-file>
            <watch-file>{context.root}/WEB-INF/flex/proxy-config.xml</watch-file>

             -->
        </redeploy>
    </system>

</services-config>

4,修改/WEB-INF/flex/remoting-config.xml

<?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>
    <!-- flex spring service在这里注入，flex调用如下：
		<mx:RemoteObject id="srv" destination="productService"/>
		<mx:Button label="Update" click="srv.updateProduct(product)"/>
		下面意思是说flex客服端在调用id为"productService" destination 的时候,
		在spring工厂中寻找id为productDAOBean的bean。
		其中：channels="my-amf"可以不要，因为缺省的channel就是它。
	-->
	<destination id="commonService" channels="my-amf">
		<properties>
			<!-- 这里指向service-config.xml里定义的工厂id -->
			<factory>my-flexfactory4spring</factory>
			<!-- 这里定义了spring的bean name -->
			<source>flex_base_service</source>
		</properties>
	</destination>
	
</service>

注意点，就这些.
