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：
2,web.xml里面 修改url的拦截器为spring.
3,修改/WEB-INF/flex/services-config.xml
4,修改/WEB-INF/flex/remoting-config.xml
注意点，就这些.

内容如下：

<value>my-polling-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

4,修改/WEB-INF/flex/remoting-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service"

<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.
