【问题描述】：
我们有一个现有的（没有 Spring）Flex/BlazeDS 应用程序，我们正在迁移它以使用 Spring BlazeDS 集成。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
我已经从 web.xml 中删除了 flex 配置，而是加载了 Spring。 当 Spring 应用上下文只包含时
<flex:message-broker/>
一切都很好，应用程序继续运行。
问题是当我定义一个消息目的地时，如下：
<flex:message-destination id="BlazeDs2" />
抛出以下错误，非常感谢任何帮助：

从我今天通过 Eclipse 调试看到的情况来看，我认为抛出异常是因为未设置 SERVICE ADAPTER 属性（忘记它是代理上的属性还是目标上的属性）。现在的问题是：我如何声明一个服务适配器 bean（或在 flex messinging-config.xml 中获得对那个的引用）？我在文档中没有看到任何这样的例子，或者有必要引用服务适配器，但似乎确实如此。非常感谢任何帮助，谢谢！
