java - 为什么 Java 值对象作为 Generic Flex 对象返回？

Question

我会尽量提供详细信息。

我正在使用 Flex(Cairngorm 2)/Java/Hibernate 创建 CRM 应用程序。我遇到的基本问题是:

我在 Java 中有一个 Customer 类，它有一个 Address 类的 ArrayList。我在 Flex 中有一个 Customer 类，它有一个 ArrayCollection of Address 类。

当我为客户调用远程对象时，我在 Flex 中取回了一个客户对象，但是 ArrayCollecion 对象的数据类型是对象而不是地址。

如果我尝试调用地址类列表，我会得到相同的结果。如果我尝试调用客户类列表，我会在 Flex 中获得客户类列表。

将 tomcat 6 与以下 jar 一起使用:

antlr-2.7.6.jar               
flex-messaging-proxy.jar
backport-util-concurrent.jar  
flex-messaging-remoting.jar

Answer 1

您应该在 SWF 中的某处引用您的 Address 类。最好的方法是在主应用程序中声明一个字段:

private var references:Object = {addressClass:Address, someOtheClass:SomeOtherClass};

问题是 ActionScript 中的 ArrayCollection 没有类型引用(Java 中的泛型)。所以类的字节码不包含在 SWF 中。
