flex 学习篇 Spring BlazeDS Integration的使用

 

 

到目前为止，网上的大部分内容都是旧的，然后各位网友都在拼命的复制黏贴那些旧内容，导致新的东西几乎被覆盖掉，甚至误导了新手，把旧的配置当成新的来用。

 Top 2. 把请求映射到Spring管理的MessageBroker,请求映射必须在3个地方被配置：

1. DispatcherServlet mapping in web.xml（在web.xml配置DispatcherServlet）

2. HandlerMapping in the Spring WebApplicationContext（配置SimpleUrlHandlerMapping标签）

3. Channel definitions in the BlazeDS services-config.xml
   
   

   <!-- Map all /messagbroker requests to the DispatcherServlet for handling -->
   <servlet-mapping>
       <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
       <url-pattern>/messagebroker/*</url-pattern>
   </servlet-mapping>  

使用这个标签<flex:message-broker />时，相当于默认调用

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

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

注：When using the message-broker config tag, a SimpleUrlHandlerMapping is installed that by default maps all incoming DispatcherServlet requests to the Spring-managed MessageBroker using a /*path pattern.
必须在BlazeDS 的services-config.xml文件中调整管道定义的映射。

<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"/>
    <properties>
        <polling-enabled>false</polling-enabled>
    </properties>
</channel-definition>
