Spring Framework On Lambda (Without Spring Boot)

Spring framework and Spring Boot are different things.

Even the repositories are distinct.

GitHub - spring-projects/spring-framework: Spring Framework

GitHub - spring-projects/spring-boot: Spring Boot

We won’t cover what is what in this article but simply you can read descriptions of these repositories.

If you need Spring Boot on Lambda AWS already has a great starter project making use of the Maven archetypes.

I am not going to bother you with blah blah blah just check out the starter I created! I also wrote some comments for your better understanding.

• You will need sam-cli. What is sam-cli?
• You will need aws-cli and configure your IAM ACCESS and SECRET

aws configure set aws_access_key_id *o*o*o*o*o*o*o*o*o
aws configure set aws_secret_access_key *o*o*o*o*o*o*o*o*o
aws configure set default.region us-east-1

• How to build and deploy

MAVEN_OPTS="-DskipTests=true" sam build 
sam deploy --stack-name ${STACK_NAME} --s3-bucket ${DEPLOY_BUCKET} --capabilities CAPABILITY_IAM

or use shell scripts under the repository but don't forget to change your deploy bucket (an empty bucket to use for the deploy process)

sh sam-build.sh
sh sam-deploy.sh

And our Lambda Function just hatched 🐣
