有可以复现的代码吗

朋友，您的邮件我已收到，我将以超光速回复您。

我这边复现不出来。 在我启动 go server 之后，在执行 samples 里面的 test 都是 passed

[Lvnszn]

https://github.com/apache/dubbo-go-samples/blob/master/integrate_test/generic/default/tests/integration/userprovider_test.go

测试代码

[Lvnszn]

复现出来了，上次写错配置了

[AlexStocks]

复现出来了，上次写错配置了

good news. reopen this issue.

[Lvnszn]

应用级 + 泛化调用 + local meta 模式会报错，获取不到接口。需要云兴佬哥帮忙确认一下是不是没有实现获取本地接口的逻辑。我这边看代码是没有实现。
remote 模式因为 zk 有个 bug，会连不上 zk，等那个 bug 修复在看看 remote 模式是不是 ok 的。

逸飞同学回复，在 pr #2168 已经把问题解掉了。
