Answer 1

Found the Issue. I was using spring-cloud-starter-aws-messaging for SQS messaging. The above dependency includes many Auto Detect classes which eventually was firing up even if they were not required.

Instead I have used spring-cloud-aws-messaging which solved the issue along with many other auto detect issues.

Answer 2

I had the same issue and I was able to prevent spring cloud aws from auto configuring the region by adding this exclude on the Spring configuration.

    @SpringBootApplication(exclude = ContextRegionProviderAutoConfiguration.class)

Answer 3

I was using springframework.cloud.aws.autoconfigure, got the same problem. The reason behind it is, we need to configure region manually when we run application in NON AWS ENVIRONMENT, ie. Local. So put this property in your application-local.properties and you should be good.

cloud.aws.region.static=us-east-1

Answer 4

If using application.yml I did it with the following

spring:
  application:
    name: App Name
  autoconfigure:
    exclude:
      - org.springframework.cloud.aws.autoconfigure.messaging.MessagingAutoConfiguration
      - org.springframework.cloud.aws.autoconfigure.context.ContextStackAutoConfiguration
      - org.springframework.cloud.aws.autoconfigure.context.ContextRegionProviderAutoConfiguration

Answer 5

I also faced the same issue but it did not get resolved after adding the aws region property. I was able to resolved the same when I removed spring-cloud-starter-aws dependency from my pom

This proved a little tricky for me to solve.

I came up with (I'll take the hard coded region out eventually but just elated it finally works!):

@Configuration
@EnableContextInstanceData
@EnableSqs
@Profile("!local")
@Slf4j
public class AwsEc2Config {

    @Bean
    public RegionProvider regionProvider() {
        return new StaticRegionProvider("eu-west-1");
    }

    @Bean
    public SimpleMessageListenerContainerFactory simpleMessageListenerContainerFactory(AmazonSQSAsync amazonSQS) {
        SimpleMessageListenerContainerFactory factory = new SimpleMessageListenerContainerFactory();
        factory.setAmazonSqs(amazonSQS);
        factory.setMaxNumberOfMessages(10);
        factory.setAutoStartup(true);
        factory.setWaitTimeOut(20);

        return factory;
    }
}
