Spring Webflow序列化生产中的麻烦 [英] Spring webflow serialization trouble in production
本文介绍了Spring Webflow序列化生产中的麻烦的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个grails应用程序，通过webflow以正确的方式做一些事情.因此，一切都在开发模式下顺利进行，我可以完成注册，并且对象可以正常序列化.但是，然后，在生产模式下，使用ssl部署在tomcat 7上时，当需要持久存储数据时会出现以下错误.简而言之，序列化是行不通的.请帮助，我目前不知道.配置的唯一区别是，我在生产中强制使用Spring安全性的https.
I have a grails app doing some stuff in the right way with webflow. So everything goes right in development mode, i can finish the registration and objects are serialized normally. But then, in production mode, deployed on a tomcat 7 with ssl, the following error appears when it's time to persist datas. In a nutshell the serialization don't work. Please help, i have no idea at the moment. The only difference of configuration is that i force https with spring security in production.

问题似乎与以下JIRA 问题有关.
请尝试在问题注释中提及的解决方法.
Please try the workaround mentioned in the issue comments.
如果您在表单中使用的命令/域对象未实现可序列化，则将显示此错误.
If your command/domain object used in your form doesn't implement serializable such an error will be displayed.
确保所有对象(域，命令，模型对象)涉及流范围(您的带有webflow的向导)实现可序列化.
Make sure that ALL objects(domain, commands, model objects) involved in the flow scope (your wizard with webflow) implement serializable.
