Spring 3 AWS Lambda for simple Hello World.

• spring Plugin for BOM and version management.
• Spotless for Code Style check and apply.
• .gitignore and .gitattributes for proper ignore and symbols check.
• .editorconfig for simple configs code style and encoding UTF-8.
• Proper Gradle and Gradle Wrapper configuration.

All Services, Components, Beans must be annotation @Component, @Service, etc. even if they are constructed manually without DI. (who knows why, that's Spring magic)

./gradlew bootBuildImage
docker build -t spring-function .
docker run --rm --entrypoint cat spring-function /function.zip > build/function.zip

sam local start-api -t sam.yaml -p 3000

Example of event to send to lambda:

{
  "name": "Steeven King"
}
