如何在Wicket 1.5中禁用序列化？

Question

我想在我的Wicket应用中关闭序列化并将所有页面/会话信息存储在RAM中。我的应用程序的用户数量很少（通常为1）；我不需要集群部署；而且我需要在请求之间缓存一些不可序列化的数据。

有没有办法让Wicket不会自动尝试序列化我的页面/会话？我尝试了在https://cwiki.apache.org/confluence/display/WICKET/Page+Storage上使用HttpSessionDataStore的建议，但这没有任何效果。我仍然得到这样的堆栈跟踪：

SEVERE: Error serializing object class com.prosc.safetynet.Administer [object=[Page class = com.prosc.safetynet.Administer, id = 0, render count = 1]]
org.apache.wicket.util.io.SerializableChecker$WicketNotSerializableException: Unable to serialize class: com.prosc.safetynet.SafetyNetSession$1
Field hierarchy is:

您可以实现自己的IPageStore来将页面保留在内存中。
