Example application to show how to send and consume messages to and from an AWS SQS queue with Spring Boot

1. An AWS Account
2. AWS Access Keys
3. Create an SQS queue

Package the application as a Docker image and run as a Docker container

To build the Docker image use the following command:

docker build -t spring-boot-sqs-example .

To run the Docker container use the following command and make sure to replace ACCESS_KEY_ID_HERE and SECRET_ACCESS_KEY_HERE with your AWS credentials:

docker run --env AWS_ACCESS_KEY_ID=ACCESS_KEY_ID_HERE --env SQS_NAME=XXXXXXXXXXX --env AWS_SECRET_ACCESS_KEY=SECRET_ACCESS_KEY_HERE --env AWS_REGION=REGION -p 8080:8080 spring-boot-sqs-example 

Using curl make the following post request to place an order which will send the message to queue

curl -i -X POST -H "Content-Type: application/json" -d "{\"reference\" : \"T000000012345\",\"userId\" :\"TEST_USERID\",\"coupon\": \"FIRSTBUY15OFF\",\"products\" : [{ \"productId\": \"PRODUCT1\",\"productName\": \"Baggy Jeans\",\"price\": 26.78,\"code\": \"T0012\"}]}"  http://localhost:8080/api/v1/orders

Use the following command to see application logs:

docker logs CONTAINER_ID --follow

In your application logs you should see the order being received and send to the queue, then see the service listening on the queue pick the message and process the order
