Grails从1.3.7升级到Grails 2.1.0。 Grails run-app已执行。没有错误。
调用webflow操作会抛出GrailsExceptionResolver错误。 grails webflow对象的状态不可序列化。我已经导航了所有类，以确保所有类都具有'可序列化'。
错误未识别未被序列化的对象，因此无法识别是否应使类字段成为瞬态而被序列化运行时忽略。

答案 0 :(得分：0)
找到了解决方案。 我的控制器服务是调用sessionFactory，它也需要是瞬态的。
代码更改： def sessionFactory =＆gt;瞬态sessionFactory。 不需要直接使任何域类变量瞬态。 解决了这个问题。
