[GitHub] [dubbo-go] flycash commented on issue #110: FAQ

Nacos Registry:  using Java internal class name as the interface value will cause registry failed.

The service configuration looks like:
```yml
services:
  "UserProvider":
    protocol : "dubbo"
    # 相当于dubbo.xml中的interface
    interface : "com.ikurento.user.UserProvider$UserService"
    loadbalance: "random"
    warmup: "100"
    cluster: "failover"
    methods:
    - name: "GetUser"
      retries: 1
      loadbalance: "random"
```
The key point is that the value `com.ikurento.user.UserProvider$UserService` contains symbol '$" which is not allowed in nacos server. The response from nacos server is 'dom name can only have these characters: 0-9a-zA-Z-._:, current: DEFAULT_GROUP@@providers:com.ikurento.user.UserProvider$UserService
'

You should rename the interface to avoid the problem.
