Integrate Spring Boot application with AWS SNS/SQS using localstack

In this video, we will see how to integrate a spring boot application with AWS SQS/SNS but in the local environment using localstack. We will create a SNS topic, a SQS queue and create SNS subscription with sqs as the protocol. We will demo how to publish notifications to SNS topic. Demo will also cover pushing/listening messages to/from SQS queue

Thanks for sharing, may I know where the properties defined in application.yaml is referred in the application?

[@visa2learn]

Those are internally used by spring cloud aws as stated in their documentation page

Can I use spring-cloud-aws-sqs dependency instead of starter dependency? But when using that my listener doesn't seem to work. is there is particular reason for using starter dependency?

[@visa2learn]

Yes the starter dependency auto-configures the SQS integration beans. So those objects are created during application startup. If you do not use the starter, you will have to create the beans yourself. docs.awspring.io/spring-cloud-aws/docs/3.1.0/reference/html/index.html#sqs-integration

[@piumidesh]

can we use multiple consumers and multiple producers using one queue.how to identify that messages these are for one consumer and these are for another consumer

[@visa2learn]

What you can do is use SNS and add multiple SQS as subscribers to this single SNS topic and then add a message filtering in SNS to route the message only to specific queues depending on what the message is. docs.aws.amazon.com/sns/latest/dg/sns-message-filtering.html
