and see #5978
dubbo supported it after 2.7.7
nacos's groupName can be set by `dubbo.registry.group`.
so,you can call `RegistryConfig#setGroup` to set nacos's groupName.
just like this:
```java
RegistryConfig registryConfig = new RegistryConfig("nacos://127.0.0.1:8848");
registryConfig.setGroup("parking");
```

see`https://github.com/apache/dubbo-samples/blob/master/1-basic/dubbo-samples-api/src/main/java/org/apache/dubbo/samples/client/Application.java`
i think dubbo app maybe not started,add`DubboBootstrap.getInstance().reference(reference).start();` and tries again,please.

i found it.
see #5349
nacos's groupName is not dubbo's group.
you must register provider to `DEFAULT_GROUP` group.
