Question

如果Akka序列化失败，我们应该怎么办，因为它无法找到混合特征之一？

使用案例类TestResult(config: TestConfiguration)构造消息。但是，由于使用SORM从数据库中获取TestConfiguration，因此实际类型为TestConfiguration with Persisted，因此出错。

我尝试使用mixoutPersisted进行混音，但它不起作用。也许是因为TestConfiguration在其字段中包含另一个Entity，但我不确定mixoutPersisted是否已经处理过这个问题。

此处有完整堆栈跟踪

使用Akka 2.3.12和SORM 0.3.18

Answer 1

这看起来两台机器中的JAR都不一样。 Java Serialization只发送对象的属性，而不是代码，所以如果一方找不到类，通常意味着接收端的CLASSPATH内容与发送端的CLASSPATH不匹配。

Akka中的序列化错误
