proxyBeanMethods exception in SCDF 2.2.1

Question

I'm trying to run a very simple stream app in SCDF 2.2.1 with minikube but I'm getting the following exception:

org.springframework.core.annotation.AnnotationConfigurationException: Attribute 'proxyBeanMethods' in annotation [org.springframework.boot.SpringBootConfiguration] is declared as an @AliasFor nonexistent attribute 'proxyBeanMethods' in annotation [org.springframework.context.annotation.Configuration].

After googling that error, I found that proxyBeanMethods is a new feature in Spring Boot 2.2 but SCDF 2.2.1 runs Spring Boot 2.1.6.

Here is my processor code:

@SpringBootApplication
@EnableBinding(Processor.class)
public class MyApplication {

    private final Log log = LogFactory.getLog(MyApplication.class);

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }

    @StreamListener(Processor.INPUT)
  @SendTo(Processor.OUTPUT)
  public String check(String payload) {

  log.info(payload);

      return payload;
  }
}

It seems that there is some kind of incompatibility but I can't figure out what I am doing wrong.

Answer 1

I change my versions to :

• Spring Boot 2.1.6
• Spring Cloud Greenwich.SR4 which uses Spring Cloud Stream 2.1.4

and now my stream is working
