Axon Framework将序列化您的整个Saga类，以便在事件出现后能够处理这些事件。因此，你在传奇中放置的任何全局字段都将被序列化。那里的连载传奇保存在"传奇商店"中。您可以阅读佐贺的参考指南->有关此方面的更多详细信息，请参阅基础结构。
此外，Axon Framework使用了几个可以配置的Serializer层。这些层是"；事件"消息，"；以及"；"通用"；，您可以在参考指南中找到。默认情况下，使用XStreamSerializer，因为它是"；反射性质"；确保所有内容都可以反序列化。
然而，随着JDK17的出现，许多类被关闭，无法进行反射访问。我很有信心，这是围绕XStream你面临的困境。从异常中可以清楚地看出。
你大致可以做两件事：
- 删除无法序列化的特定类。请注意，特别是您在Saga中连接的服务应该是
transient，因为这些服务在其他方面都是反序列化的 - 将
XStreamSerializer替换为JacksonSerializer
这使得XStream作为默认Serializer不太理想。遗憾的是，改变这一点对Axon Framework用户来说是一个突破性的改变，所以框架仍然坚持XStream。
