Code example

RabbitMQ Configuration

@Configuration
class RabbitConfig {

    @Bean("paymentRequestQueue")
    fun requestQueue(): Queue =
        Queue(AMQPConstants.QUEUE_PAYMENT_REQUESTS)

    @Bean("paymentResponseQueue")

        }

    @Bean
    fun rabbitTemplate(conFactory: ConnectionFactory): RabbitTemplate {
        val rabbitTemplate = RabbitTemplate(conFactory)
        rabbitTemplate.messageConverter = ProtobufMessageConverterAMQP(
            PaymentResponse.getDefaultInstance()
        )
        return rabbitTemplate
    }
}

Consumer

@Component
class PaymentRequestConsumer {
    @Autowired
    lateinit var responseProducer: PaymentResponseProducer

    @RabbitListener(queues = [AMQPConstants.QUEUE_PAYMENT_REQUESTS])
    suspend fun process(
        @Header(AmqpHeaders.CHANNEL) channel: Channel,
        @Header(AmqpHeaders.DELIVERY_TAG) deliveryTag: Long,
        @Payload requestMsg: PaymentRequest
    ) {
        println("Processed request! ${requestMsg.id}")
        responseProducer.paymentRespond(paymentResponse {
            id = 1
            status = PaymentResponse.Status.SUCCESSFUL
        })
        channel.basicAck(deliveryTag, false)
    }
}

Producer

@Component
class PaymentResponseProducer {
    @Autowired
    private lateinit var template: RabbitTemplate

    @AsyncPublisher(
        operation = AsyncOperation(
            channelName = AMQPConstants.QUEUE_PAYMENT_RESPONSES
        )
    )
    @AmqpAsyncOperationBinding
    fun paymentRespond(response: PaymentResponse) {
        template.convertAndSend(AMQPConstants.QUEUE_PAYMENT_RESPONSES, response)

Welcome to Springwolf. Thanks a lot for reporting your first issue. Please check out our contributors guide and feel free to join us on discord.

Hi @slava110
Thank you for the detailed report.

Enabling the debug logs will potentially add a bit more context: https://www.springwolf.dev/docs/faq#show-debug-output-in-the-logs

Can you share the payload PaymentResponse class? I suspect some recursive structure, which regardless should be handled by Springwolf.

Hi. Thank you for quick response.
Here is my log after changing SpringWolf's logging level to DEBUG:

PaymentResponse class is generated using ProtoBuf schema so it would be difficult to read generated mess :x
It also extends GeneratedMessage class available here
Here is my protobuf definition as well as PaymentResponse class generated from this definition:

payment.proto

syntax = "proto3";

package model;

option java_package = "com.microdelivery.model";

message PaymentRequest {
  int32 id = 1;
  int32 userId = 2;
  string paymentMethod = 3;
  repeated Good goods = 4;
}

message Good {
  int32 id = 1;
  uint64 price = 2;
}

message PaymentResponse {
  int32 id = 1;
  Status status = 2;
  string redirectUrl = 3;

  enum Status {
    SUCCESSFUL = 0;
    FAILED = 1;
    ABORTED = 2;
    UNAVAILABLE = 3;
  }
}

To generate this mess I'm using com.google.protobuf:protobuf-kotlin:4.28.3
I'm using ProtoBuf because I need to communicate with other microservices written in other languages (for our university project). It generates classes automatically using same format (.proto files) for everyone. If you happen to know what else I can use to achieve something like that - I'd like to know c:

Thank you, we will have to look into it.
Actually, on second thought, it is interesting that the protobuf causes a stackoverflow for avro, which is different wire protocol.

In case you want to experiment, debug and contribute:
We have a basic protobuf example project, probably with similar dependencies: https://github.com/springwolf/springwolf-core/blob/master/springwolf-examples%2Fspringwolf-kafka-example%2Fsrc%2Fmain%2Fproto%2FExamplePayloadProtobufDto.proto
Just fork springwolf-core, put your proto file inside the file above and create a consumer/producer as you have done. Whether it is kafka or rabbitmq likely does not matter for this.

Hi. I've tested both my and your schema in https://github.com/springwolf/springwolf-core/tree/master/springwolf-examples/springwolf-amqp-example project
I've added protobuf dependencies from kafka module, copied your proto from kafka module, tried running the server, copied my own proto, tried running the server again.
It didn't produce error immediately, however, it crashed after some time (or maybe after some time after I try to access docs endpoint? Probably not). It produces a bit different error, but it is also related to StackOverflow and Avro removeProperties (but more similar to this one somehow: #830 (although, it's probably unrelated, since author said it's their generator's issue or something)).

If you have configured springwolf in init lazy mode, the endpoint must be called first.

It sounds like that you have adapted the example already. Do you mind putting it on a branch and open a PR? That improves chances that we can quickly reproduce it.
(Similar to i.e.: #764 )

When running gradlew test (ApiSystemTest), the error/exception should appear.

Just using your proto file did not reproduce the error for me, i havent looked into the dependencies nor used both request and response object together.

[slava110]

I've created PR #1053. I can also upload to GitHub my own project's source code c:

Just using your proto file did not reproduce the error for me, i havent looked into the dependencies nor used both request and response object together.

Maybe it's a problem specifically with protobuf + RabbitMQ mix?

[slava110]

I've used debug mode and UnknownFieldSet from ProtoBuf seems to be the problem? It seems to reference itself in property defaultInstanceForType. As I understand:

1. removeAvroProperties called for UnkownFieldSet schema
2. It gets schema properties, finds defaultInstanceForType property, calls removeAvroProperties on it
3. This property has $ref to UnkownFieldSet so during this removeAvroProperties call execution goes into schema.get$ref() != null condition. Where removeAvroProperties called on referenced class
4. removeAvroProperties called for UnkownFieldSet schema (referenced class)
5. Cycle repeats

I might be wrong cause I have no idea what's going on with avro properties and haven't dig into your codebase much. So take it with a grain of salt

[timonback]

Hi @slava110,
That is exactly right, there is a cycle from UnknownFieldSet -> defaultInstanceForType and then back again.
The avro post processor does not handle it, and it only triggers when avro (amqp) is used together with protobuf.

I opened #1062 to address it. We will probably review it on Friday.

Still, I am surprised why all these fields appear in the Schema (in additional to all the other protobuf classes). The protobuf file in the kafka examples does not include all these additional fields in the Schema, and thereby no cycle...

[slava110]

I've added ObjectMapperConfiguration from Kafka example module to AMQP example module and it fixed the issue. That's why Kafka example works fine

[timonback]

#1062 is merged now.

Thank you for the ObjectMapperConfiguration reminder, I updated the website to add some information for Protobuf: springwolf/springwolf.github.io#99

[github-actions]

The change is staged for release and will be part of the next release.

If you want to try and verify it in your application today,
use the latest 1.X.0-SNAPSHOT build as described in our README.md > Testing SNAPSHOT version

Thank you for the report/contribution!
