Axon 抱怨 com.thoughtworks.xstream.converters.ConversionException：調用方法失敗

Question

我正在嘗試將 mysql 與 JPA 一起用於軸突事件存儲，我遇到了這個問題，它對我使用 InMemoryEventStorageEngine。

我已經用軸突服務器和 InMemoryEventStorageEngine 試過了，它的工作原理。

任何幫助都非常感謝謝謝

Answer 1

@dawit你得到解決方案還是解決它

Answer 2

正如@Steven 提到的序列化僅在您嘗試將事件存儲在數據庫中時才有效，並且您可以在配置應用程序屬性中輕松配置事件序列化，我能夠使用此配置解決它

axon.serializer.general = jackson
axon.serializer.events = jackson
axon.serializer.messages =Jackson
