Serverless Spring Boot 2 example

The goal of this sample is to demonstrate the use of the aws-serverless-java-container with Spring MVC

The StreamLambdaHandler object is the main entry point for the Lambda.

The application can be deployed in an AWS account using the Serverless Application Model. The template.yml file in the root folder contains the application definition.

Pre-requisites

Deployment

In a shell, navigate to the root folder of the repository and use the SAM CLI to build a deployable package

$ sam build

This command compiles the application and prepares a deployment package in the .aws-sam sub-directory.

To deploy the application in your AWS account, you can use the SAM CLI's guided deployment process and follow the instructions on the screen

$ sam deploy --guided

Once the deployment is completed, the SAM CLI will print out the stack's outputs, including the new application URL.
