Question

I am trying to use the amazon sns service But getting Unable to load credentials from any chain exception. Credentials are stored in application.properties file and i have also tried by storing the credentials in java system properties. But same error comes up.

Bean for sns getting credendtials from properties file .

    public class SnsBean {
        
        private final SnsConfiguration snsConfiguration;
        
        @Primary
        @Bean
        public AmazonSNSClient getSnsClient() {
            var credentials = snsConfiguration.getPrimary();
            return (AmazonSNSClient) AmazonSNSClientBuilder.standard().withRegion(Regions.US_EAST_2)
                    .withCredentials(new AWSStaticCredentialsProvider(
                            new BasicAWSCredentials(credentials.getAccessKey(), credentials.getSecretKey())))
                    .build();
        }
    }

Answer 1

The issue is that you have not setup your creds properly. Once you do so, you can use the AWS SDK for Java within a Spring Boot app. To work with the AWS SDK for Java V2 (I'm answering this question with the recommended Java Version - which is V2), you need to choose one of the supported credential providers.

To read about the supported credential provider chains, see the Java V2 DEV Guide here:

Using credential

Most of the examples in the AWS Github example repo assumes that your credentials are located in a file named credentials located here:

• Windows - C:\Users<yourUserName>.aws\credentials
• Linux, macOS, Unix - ~/.aws/credentials

Once you set a valid credential provider, you can create AWS Service client successfully using the AWS SDK for Java.

To help you with Amazon SNS and a Spring Boot app, there is an example of using the Amazon SNS Service Java API V2 within a Spring BOOT app. This works well, as shown in the screenshot.

This shows the result of the listSubscriptionsByTopic method that belongs to the software.amazon.awssdk.services.sns.SnsClient object. Once you setup a credential provider, the SnsClient works fine in a Spring Boot app.

To learn how to successfully create an Amazon SNS app using Spring BOOT, see:

Creating a Publish/Subscription Spring Boot Application

Remember to place your creds in a file in the location specified above (or choose another way such as using Environment variables that is used in this Spring BOOT example).
