### Environment
* Dubbo version: 2.7.5
* Operating System version: windows10
* Java version: 1.8
### Steps to reproduce this issue
ProviderConfig
```
@Configuration
@EnableDubbo(scanBasePackages = "org.apache.dubbo.demo.provider")
@PropertySource("classpath:/spring/dubbo-provider.properties")
@ComponentScan
static class ProviderConfiguration {
@Bean
public RegistryConfig registryConfig() {
RegistryConfig registryConfig = new RegistryConfig();
registryConfig.setAddress("nacos://192.168.1.101:8848");
// 设置部分配置进入配置中心
registryConfig.setSimplified(true);
return registryConfig;
}
@Bean
public ConfigCenterConfig configCenterConfig() {
ConfigCenterConfig configCenterConfig = new ConfigCenterConfig();
configCenterConfig.setAddress("nacos://192.168.1.101:8848");
return configCenterConfig;
}
@Bean
public MetadataReportConfig metadataReportConfig() {
MetadataReportConfig metadataReportConfig = new
MetadataReportConfig();
metadataReportConfig.setAddress("nacos://192.168.1.101:8848");
return metadataReportConfig;
}
}
```
when enabled `setSimplified(true)`, nacos services name is `providers::::`
because
NacosRegistry.java
```
private String getServiceName(URL url) {
return getServiceName(url, url.getParameter(CATEGORY_KEY,
DEFAULT_CATEGORY));
}
private String getServiceName(URL url, String category) {
return category + SERVICE_NAME_SEPARATOR + url.getColonSeparatedKey();
}
```
URL.java
```
/**
* The format is "{interface}:[version]:[group]"
* @return
*/
public String getColonSeparatedKey() {
StringBuilder serviceNameBuilder = new StringBuilder();
append(serviceNameBuilder, INTERFACE_KEY, true);
append(serviceNameBuilder, VERSION_KEY, false);
append(serviceNameBuilder, GROUP_KEY, false);
return serviceNameBuilder.toString();
}
```
when enabled `setSimplified(true)`, interface will not register to
Registry。please see
