horizonzy opened a new issue #8176:
URL: https://github.com/apache/dubbo/issues/8176
### Environment
* Dubbo version: 3.0
### Steps to reproduce this issue
start dubbo-demo-triple ApiProvider's main.
### There are two problem
1.metadataService is inner service at dubbo, it need dubbo protocol to
export, but dubbo-demo-triple module didn't import dubbo-rpc-dubbp dependency.
2.This module use old coding model, it use serviceConfig.export directly,
didn't use DubboBootStrap to start. The old coding model exist problem, it's
can't add registryConfig to configManager, so didn't use registryConfig as
metadataReportConfig.
At 3.0, we need metadataReport to do service name mapping.
If there is an exception, please attach the exception trace:
```
java.lang.IllegalStateException: the metadata report was not inited.
