Apache Dubbo Component

Java SDK (apache/dubbo)

Dubbo Version

Dubbo 3.3.4、 jdk 17

Steps to reproduce this issue

use dubbo-sample-master
use dubbo-samples-triple-grpc, the old protobuf file is follow:

syntax = "proto3";

option java_multiple_files = true;

package org.apache.dubbo.samples.tri.grpc;

message GreeterRequest {
  string name = 1;
}

message GreeterReply {
  string message = 1;
}

service Greeter{
 // key, the first letter is lowercase
  rpc greet(GreeterRequest) returns (GreeterReply);

  rpc biStream(stream GreeterRequest) returns (stream GreeterReply);

  rpc serverStream(GreeterRequest) returns (stream GreeterReply);

}

update protobuf file

syntax = "proto3";

option java_multiple_files = true;

package org.apache.dubbo.samples.tri.grpc;

message GreeterRequest {
  string name = 1;
}

message GreeterReply {
  string message = 1;
}

service Greeter{
 // key, Convert the first letter to uppercase
  rpc Greet(GreeterRequest) returns (GreeterReply);

  rpc biStream(stream GreeterRequest) returns (stream GreeterReply);

  rpc serverStream(GreeterRequest) returns (stream GreeterReply);

}

compile and run
Requests starting with uppercase or lowercase letters， call on http
The first http request detail (rpc method name is uppercase):

POST localhost:50053/org.apache.dubbo.samples.tri.grpc.Greeter/greet
Content-Type: application/json

{
  "name": "John"
}

What you expected to happen

Call 'localhost: 50053/org.apache.dubbo.samples.tri.grpc.Greeter/Greet'
Or 'localhost: 50053/org.apache.dubbo.samples.tri.grpc.Greeter/greet' via HTTP succeeded, do not all fail

Anything else

General proto file specifications, The first character of the RPC method name is capitalized, and we have a large number of proto files with history that use RPC method names starting with uppercase characters

Are you willing to submit a pull request to fix on your own?

Yes I am willing to submit a pull request on my own!

Code of Conduct

I agree to follow this project's Code of Conduct

The text was updated successfully, but these errors were encountered:

method name in proto is capitalized (apache#15291)

service Greeter{
 // key, Convert the first letter to uppercase
  rpc Greet(GreeterRequest) returns (GreeterReply);

  rpc biStream(stream GreeterRequest) returns (stream GreeterReply);

  rpc serverStream(GreeterRequest) returns (stream GreeterReply);

}

methods name biStream and serverStream do not comply with protobuf regulation: service names and method names should use TitleCase. see details at https://protobuf.dev/programming-guides/style/#services

zrlw · 2025-04-02T01:18:46Z

you might refer to this proto: https://github.com/apache/dubbo/blob/3.3/dubbo-rpc/dubbo-rpc-triple/src/main/proto/health.proto

service Health {
...
  rpc Check(HealthCheckRequest) returns (HealthCheckResponse);
...
  rpc Watch(HealthCheckRequest) returns (stream HealthCheckResponse);
}

i tested on current dubbo 3.3 branch and didn't find the issue.
here is my operations:

modify pom.xml of dubbo-demo-spring-boot-idl,
(1) add dependencies

    <dependency>
      <groupId>com.google.protobuf</groupId>
      <artifactId>protobuf-java-util</artifactId>
      <version>3.25.6</version>

(2) add plugins, set os.detected.classifier to windows-x86_64 since i test it on windows.
