Going serverless with Spring Function and AWS

Sample demo project to show the use of sprint cloud functions, create lambda function, deploy on AWS and write data to Dynamo DB. This project is part of an blog post that can be found in the link

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

Java JDK 8
Serverless Framework - The framework used for deploying the application
AWS CLI - setup aws cli

Installing

Get the project from GIT "git clone https://github.com/popovski/spring-cloud-function-aws.git"
Get amazon accesskey from your AWS account and set the value in project -> application.properties -> amazon.aws.accesskey
Get amazon secretkey from your AWS account and set the value in project -> application.properties -> amazon.aws.secretkey
Go to root of the project and run ".\mvnw clean package" - this will build the jar file

When the deployment process finish successfully as a result of the serverless deployment process link for the POST api gateway, we will use the link to trigger the aws lambda function

Running the tests

.\mvnw test - command for running the junit tests

Junit test will start the project locally and trigger the function

Deployment

For deployment we will use serverless CLI

"serverless deploy --region us-east-1 --aws-profile YOUR_PROFILE" - this command will start deploy the spring function on AWS, replace the YOUR_PROFILE with the "/.aws/credentials" file that is used for setup the AWS cli

Built With

Demo

After the serverless deployment finish, as a response we will get POST rest end point of the AWS API Gateway. Use Postman to make a POST request using payload

{ "firstName":"Nikola", "lastName":"Popovski" }
