Question

我有一个grails应用程序以正确的方式使用webflow做一些事情。所以一切都在开发模式下，我可以完成注册，对象正常序列化。但是，在生产模式下，使用ssl部署在tomcat 7上，当需要持久保存数据时会出现以下错误。简而言之，序列化不起作用。请帮忙，我现在不知道。配置的唯一区别是我强制https在生产中使用spring security。

Answer 1

<强>更新

看起来这个问题可能与the following JIRA问题有关。

请尝试问题评论中提到的解决方法。

如果表单中使用的命令/域对象未实现可序列化，则会显示此类错误。

确保流范围中涉及的所有对象（域，命令，模型对象）（带有webflow的向导）实现可序列化。

Answer 2

 <hibernate-configuration> <session-factory name="sessionFactory">
