jboss memcacehd kryo flex

Question

我有一个jboss 5.1，我正在尝试使用memcached和kryo序列化来实现会话复制。一切都很好，但我的应用程序中有一个页面，它的左侧有一些flex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了，无法解决这些问题。请帮帮忙

要序列化您的HTTPSession，您需要序列化HttpFlexSession，而它可能是不可序列化的(或者您正在通过禁用serializable对象上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序列化的HttpFlexSessionSerializer.java，然后你应该能够用kryo来序列化你的flex会话。
