From what I understand, if the `protocol` field isn’t set in `@DubboReference` , Dubbo will use the value from the config file — like `dubbo.consumer.protocol` or `dubbo.protocol.name` . And that works fine in most cases when `stub.event` is not involved.(In this issue, when I use `onconnect` , it automatically sets `stub.event` to `true` .) > > And that’s where my question comes in. Why is `stub.event` treated differently? When I use `onconnect` or `ondisconnect` , why do I have to explicitly set the `protocol` field in `@DubboReference` for it to work? It’s not really explained in the official docs, so I’m not sure if this is expected behavior or a bug. the correct configuration item is `dubbo.consumer.protocol: dubbo`. You can use it in the configuration file instead of setting it in the annotations. If you have set the `onconnect` or `ondisconnect` options，proxy clients need to perform service export to listen for local network events, the `export` process need the protocol value. can look at `org.apache.dubbo.rpc.proxy.wrapper.StubProxyFactoryWrapper#getProxy(org.apache.dubbo.rpc.Invoker<T>, boolean)` and `org.apache.dubbo.remoting.exchange.support.ExchangeHandlerAdapter#invoke` -- This is an automated message from the Apache Git Service.
