This is a Spring Boot 3 microservice project which uses Spring Cloud Functions and can be compiled with GraalVM and deployed to AWS Lambda.

Prerequisites

Before you begin, ensure you have met the following requirements:

• Java 17: Ensure you have Java 17 installed for development.
• Docker: Needed for creating the native image.
• AWS Account: Required for deployment on AWS.

Building and Creating Native Image

To compile and create a native image, follow these steps:

1. Run the Docker command to start the container:
