## What it is
A Java library that lets applications built with frameworks like Spring, Spring Boot, Jersey, Struts, and Spark run inside AWS Lambda. It translates API Gateway proxy integration requests and responses so existing Java web apps can be deployed serverlessly.

## Use cases
- run a Spring Boot app on AWS Lambda
- deploy a Jersey JAX-RS REST API serverlessly
- migrate an existing Java web app to Lambda without rewriting
- serve REST APIs through API Gateway from Lambda
- host a Sparkjava or Struts application in AWS Lambda

## When to avoid
- you are building a new service not tied to Java web frameworks
- you need long-running processes or WebSockets beyond Lambda's model
- you deploy outside AWS Lambda

## Facets
- artifact type: library
- maturity: active
- function: http-server, middleware, web-framework, api-framework
- domain: backend, web-development, cloud-computing, apis
- platform: jvm, serverless
- tags: aws-lambda, spring-boot, jersey, jax-rs, api-gateway, sparkjava, struts, java
