我们正在迁移使用Spring BlazeDS Integration的现有（无Spring）Flex / BlazeDS应用程序。在Maven pom中，依赖于 spring-flex-core 1.5.2.RELEASE ，这带来了 Spring 3.0.5-RELEASE 和 BlazeDS 4.0 .0.14931
我已从web.xml中删除了flex配置，而是加载了Spring。 当Spring应用程序上下文包含
时<flex:message-broker/>
一切都很棒，应用程序继续运行。
问题是当我定义消息目的地时，如下所示：
<flex:message-destination id="BlazeDs2" />
抛出以下错误，非常感谢任何帮助：

请提供您的services-config.xml 和 web.xml。
同时，in the doc部分7.3到7.6提供了有关消息目的地的有用信息。

Please change your exposed bean tag to "remoting-destination" from "message-destination",
e.g:-
<flex:remoting-destination ref="myService" />
Make sure your "web.xml" file looks like somewhat this
"<web-app>
<display-name>dzone-server</display-name>
<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/application-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Map /spring/* requests to the DispatcherServlet -->
<servlet-mapping>
<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
<url-pattern>/spring/*</url-pattern>
</servlet-mapping>
</web-app>"
