Error in startup application when using @ServiceActivator in Spring cloud Stream

Question

I put @ServiceActivator to log all messages that gave error to kafka:

@ServiceActivator(inputChannel = "errorChannel")
public void handleErrors(final ErrorMessage in) {
    log.error("encountered exception" + em.toString());
}

and I'm also setting the errorChannelEnabled flag to true:

  cloud:
    stream:
      function:
        definition: consumeProfile
      bindings:
        #kafka producer
        produceProfile-out-0:
          binder: kafka
          destination: profile
          producer:
            use-native-encoding: true
            error-channel-enabled: true

the problem is when I'm uploading the application I'm getting this error log:

org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'profileListener.handleErrors.serviceActivator': Requested bean is currently in creation: Is there an unresolvable circular reference?

my application does not crash because of this exception, but I wanted your help to understand the reason, thank you

Answer 1

Thank you for the sample.

This is a bug in the IntegrationMBeanExporter : we try to pull an endpoint bean at the moment it is created by the MessagingAnnotationPostProcessor .

So, please, raise a GH issue in the Spring Integration project and we will see what we can do.

Meanwhile as a workaround you can turn off JMX by respective Srping Boot property: spring.jmx.enabled=false . We have it auto-configured by default for Spring Integration regardless of Spring Boot default decision:

@ConditionalOnProperty(prefix = "spring.jmx", name = "enabled", havingValue = "true", matchIfMissing = true)
protected static class IntegrationJmxConfiguration {
