@CodingAdai hi,我这边跑了dubbo-go-samples里的一个例子，发现是可以用group+version进行调用的，具体地址在：https://github.com/apache/dubbo-go-samples/tree/master/rpc/dubbo
java服务端的配置：
<img width="1268" alt="image" src="https://user-images.githubusercontent.com/20033804/212850144-ba312d7f-4c60-4e8b-929c-7231afd7f660.png">
golang客户端的配置：
<img width="572" alt="image" src="https://user-images.githubusercontent.com/20033804/212850343-b24861e5-bbc8-440c-9337-e09e97c75f94.png">
指定version可以调用到不同的函数。所以你调用失败应该是哪里的配置有问题，可以对比下你的demo和这个例子，后面我抽空再看下你上面的demo。

> 我这边确认了，dubbo协议下与Java互通没有该问题， 但在triple（dubbo3）协议下， 因dubbo go consumer在调用时version和group参数设置不正确，造成 provider 返回 service not found 报错。我这边来修复它。
good news. thank you. please go on.

补充下这个问题：
代码demo：https://github.com/CodingAdai/java-go-dubbo.git （Go consumer call Java provider on triple）
加version之后，Java提供者收到请求后，会返回service not found，grpc status =13，debug level 关键日志如下：

之前感觉是dubbo-go可能有问题，根据自己debug和日志，估计是dubbo java可能有问题，因为dubbogo是正确请求了。源码理解不够， @zhaoyunxing92
@ZLBer 你们有时间看下，有需要的话， dingtalk @我 。如果确认是Dubbo java 可能有问题的话，我再到dubbo java那边提下。

好的，我对比测试下，我用的dubbo java 不是v3.0.3，我看下是否为我用的版本有相应问题。

我这边确认了，在triple协议下， 因dubbo go consumer在调用时version和group参数设置不正确造成 provider 返回 service not found 报错，我这边来修复它。
