c++ - 点燃 C++ : serialization class not found in cache store

Question

我正在尝试使用缓存存储来实现持久性。我已经使用二进制类型模板实现了用户定义对象的序列化。但是仍然在 spring xml 中配置 cassandra 缓存存储时。我收到类似反序列化器未找到或类 ID 未找到预期的错误。我什至尝试过文档中可用的二进制配置，但它没有用。有人可以帮助解决这个问题。

错误代码:

如果您只有 C++ 类的定义，您可能需要在 CacheConfiguration 上设置 storeKeepBinary。另外，您可能想看看 this ticket ，因为 Cassandra 商店存在一些问题。它似乎处于“补丁可用”状态，因此修复似乎很快就会成为大师。
