Spring Boot 3 application on AWS Lambda - Part 3 Develop application with AWS Serverless Java Container

• AWSLambdaJavaSnapStart

  17 4 9.1 Java

For the sake of explanation we'll use our Spring Boot 3.2 sample application and use Java 21 runtime for our Lambda functions.

• serverless-java-container

  37 1,450 9.3 Java

  A Java wrapper to run Spring, Spring Boot, Jersey, and other apps inside AWS Lambda.

  

The key dependency to make it work and translate between Spring Boot 3 (web annotation) model and AWS Lambda is the dependency to the artifact aws-serverless-java-container-springboot3 defined in the pom.xml. It's based on Serverless Java Container which natively supports API Gateway's proxy integration models for requests and responses, and we can create and inject custom models for methods that use custom mappings.

If we look into the whole dependency tree, we'll discover another dependency spring-cloud-function-serverless-web which aws-serverless-java-container-springboot3 requires which is the collaboration effort between Spring and AWS Serverless developers. It provides Spring Cloud Function on AWS Lambda functionallity. We'll look deeper into the capabilities of Spring Cloud Function on AWS Lambda in one of my upcoming articles.
