SNS Endpoint demo using Spring

Provisioning

You'll need to run the demo somewhere publically available, so that AWS can send messages to the app. For example, an EC2 instance or DigitalOcean droplet.

Running the app

1. Build it with mvn clean package

2. Copy the jar file from target/ to the public host

3. Run it with java -jar sns-demo-0.0.1-SNAPSHOT.jar

Setting up SNS

1. In the SNS console, create a new topic. Call it whatever you want. Copy the ARN for a subsequent step.

2. Create an HTTP subscription using the ARN from above and a URL to your app e.g. http://1.2.3.4/notify.

3. The demo app's logs should show AWS sending a subscription request.

Sending a test message

1. Ihe SNS console, with your topic selected, click "Publish to topic".

2. Select "JSON" as the message type.

3. Enter the following in the message box.

   { "default": "{\"foo\": \"bar\"}" }

4. The demo app's logs should show AWS delivering the message and the demo app logging the payload.
