文章描述了一个在使用Dubbo框架时遇到的异常情况，具体表现为`java.io.StreamCorruptedException:invalidstreamheader:77D30000`。该问题与序列化有关，特别是客户端和服务端的`dubbo.protocol.serialization`配置不一致导致。解决方案是确保两端配置相同，并推荐使用成熟的序列化方式如json。此外，文章还提到当客户端使用服务端未知的子类作为参数时，会导致类型转换异常，需避免这种情况并保持接口定义的一致性。

java.io.StreamCorruptedException: invalid stream header: 77D30000 ; Decode rpc invocation failed
