我有一个 jboss 5.1 AS，我在其中尝试使用 memcached 和 kryo 序列化实现会话复制。一切正常，但我的应用程序中有一个页面，它的左侧有一些弹性功能。当我在 GUI 中单击此页面时，kryo 序列化失败并显示以下堆栈跟踪：

Caused by: com.esotericsoftware.kryo.SerializationException: Unable to serialize object of type: flex.messaging.HttpFlexSession

我已经被困了很多天，无法解决问题。请帮忙

要序列化您的 HTTPSession，您需要序列化 ​​HttpFlexSession，它可能是不可序列化的（或者您通过禁用 Serializable 对象的序列化来使用严格的 kryo 配置）。

您应该向 kryo 提供一个类来序列化 HttpFlexSession：

Kryo kryo = new Kryo();
kryo.register(HttpFlexSession.class, new HttpFlexSessionSerializer(kryo));

然后你需要实现应该扩展 Serializer 的 HttpFlexSessionSerializer.java 然后你应该能够用 kryo 序列化你的 flex 会话。
