amazon web services - Spring boot startup error for AWS application : There is not EC2 meta data available

Question

I am getting the below error when I am trying to run a Spring boot-AWS application locally :

There is not EC2 meta data available, because the application is not running in the EC2 environment. Region detection is only possible if the application is running on a EC2 instance

My aws-config.xml looks like below :

<aws-context:context-credentials>
<aws-context:simple-credentials access-key="*****" secret-key="*****"/>
</aws-context:context-credentials>  
<aws-context:context-region auto-detect="false" region="ap-south-1" />  
<aws-context:context-resource-loader/>  
<aws-messaging:annotation-driven-queue-listener max-number-of-messages="10" wait-time-out="20" visibility-timeout="3600"/> 

I am trying to listen with a SQSListner in the below class :

@Configuration
@EnableSqs
@ImportResource("classpath:/aws-config.xml")
@EnableRdsInstance(databaseName = "******", 
               dbInstanceIdentifier = "*****", 
               password = "******")
public class AwsResourceConfig {
    @SqsListener(value = "souviksqs", deletionPolicy = SqsMessageDeletionPolicy.ON_SUCCESS)
    public void receiveNewFileUpload(S3EventNotification event) {
        try {
            if ( event != null && !CollectionUtils.isNullOrEmpty( event.getRecords() ) && event.getRecords().get( 0 ) != null ) {
                S3Entity entry = event.getRecords().get(0).getS3();
                System.out.println("############ File Uploaded to ###################### " + entry.getBucket().getName() + "/" + entry.getObject().getKey());
            }
        } catch (Exception e) {
            System.out.println("Error reading the SQS message " + e);
            
        }
    }
}

Edit : Just noticed that the error comes when I include the following aws-messaging maven dependency :

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-aws-messaging</artifactId>
     <version>${spring-cloud-aws-version}</version>
</dependency>

I am using spring-cloud-aws-version - 1.2.1.RELEASE

Answer 1

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
