I have reproduced this problem, and the problem can be more specific:
The Triple protocol is not working on Spring integrated with Dubbo.

使用注解引用时，再次指定protocol=tri，解决
@DubboReference(providedBy = "feedback-provider", check = false, protocol = "tri")
private HelloService helloService;
看起来是provider配置里services key 为`interface:protocol`的原因（"com.example.feedback.api.service.HelloService:tri"）。
但是不知道为什么在注解引用时，并没有把dubbo.protocol.name=tri这个信息加到后面，需要在reference里再次指定

@feng996 I have found the cause of the problem which is not related to `dubbo-spring-boot-starter` as I first thought.
The source is in `org.apache.dubbo.config.metadata.ServiceInstanceHostPortCustomizer`, let's have a look:
```java
@Override
public void customize(ServiceInstance serviceInstance) {
String host = null;
int port = -1;
// ......
Set<URL> urls = writableMetadataService.getExportedServiceURLs();
if (CollectionUtils.isNotEmpty(urls)) {
ApplicationModel applicationModel = serviceInstance.getApplicationModel();
String preferredProtocol = applicationModel.getCurrentConfig().getProtocol();
// The default value of preferredProtocol is dubbo.
if (preferredProtocol != null) {
for (URL exportedURL : urls) {
// The protocol of exportedURL is tri
// because of tri != dubbo, the host and port will not be assigned values.
if (preferredProtocol.equals(exportedURL.getProtocol())) {
host = exportedURL.getHost();
port = exportedURL.getPort();
break;
}
}
} else {
URL url = urls.iterator().next();
host = url.getHost();
port = url.getPort();
}
// If not the port of instace > 0, the application instance will not be registered to RegistryCenter(like Nacos, Zookeeper).
// As a result, the consumer can't find the avaliabe providers when our settging is registry-mode=instance
if (serviceInstance instanceof DefaultServiceInstance) {
DefaultServiceInstance instance = (DefaultServiceInstance) serviceInstance;
instance.setHost(host);
instance.setPort(port);
}
}
}
```
For the moment, if you want both consumer and provider to force using `Application Discovery` in tri protocol, just change one line config of provider as follows:
```yaml
dubbo:
application:
metadata-type: remote
register-mode: instance
protocol: tri <==== HERE, set preferredProtocol as tri
```
But, Dubbo official also needs to do two things for further promotion:
1. Complete the docs: [Triple协议迁移指南](https://dubbo.apache.org/zh/docs/migration/migration-triple/) as soon as possible
2. The logic of preferredProtocol was not user-friendly, we maybe should optimize it.
