I am trying to understand how exactly the errorChannelEnabled property works for Spring Cloud Stream. I am using version 4.0.4 of Spring Cloud Stream and rabbit binder.
Based on this answer, I understand that there is a global error channel named errorChannel and a per binding error channel for producers which is created when this errorChannelEnabled property is set to true. The name of this channel is <destination>.<group>.errors.
However, this does not seem to work for this simple application:
package com.example.rabbittests;
import java.util.function.Supplier;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.integration.annotation.ServiceActivator;
import org.springframework.messaging.support.ErrorMessage;
@SpringBootApplication
public class RabbitTestsApplication {
public static void main(String[] args) {
SpringApplication.run(RabbitTestsApplication.class, args);
}
@Bean
public Supplier<String> supplier_err() {
return () -> {
System.out.println("Sending msg...");
throw new RuntimeException("An error occurred...");
};
}
@ServiceActivator(inputChannel = "atest1.g1.errors")
public void processError(ErrorMessage msg) {
System.out.println("My test error: " + msg);
}
}
Following is my application.properties file:
spring.cloud.function.definition=supplier_err
spring.cloud.stream.bindings.supplier_err-out-0.destination=atest1
spring.cloud.stream.bindings.supplier_err-out-0.group=g1
spring.cloud.stream.bindings.supplier_err-out-0.producer.error-channel-enabled=true
It looks like it is creating unknown.channel.name channel for error channel as in the logs, the following line is printed:

Can someone explain why this code does not catch producer errors? Is there some other way to use errorChannelEnabled property?
Thanks
I found the issue Error channel name collision #2507. It seems the pattern <destination>.<group>.errors doesn't work anymore for the InputChannel according to this issue.
I added a Consumer for error messages, as described in the section Spring Cloud Stream - Handle Error Messages, but this doesn't work either. Doesn't matter if I add the error-handler-definition for a specific binder or as default error handle. The consumer never receives any error.
I think the spring.io documentation is bad, because the error-handler-definition works only for consumer errors and not for producer errors. To find that out, I had to read the SpringCloudAzure5x integration of spring from Microsoft. There they distinguish between outbound and inbound messages.
The only way I can get it work is with the InputChannel errorChannel, but a global error channel is quite messy for us to handle.
