The aws-serverless-java-container makes it easy to run Java applications written with frameworks such as Spring, Spring Boot, Apache Struts, Jersey, or Spark in AWS Lambda.
Serverless Java Container natively supports API Gateway's proxy integration models for requests and responses, you can create and inject custom models for methods that use custom mappings.
Currently the following versions are maintained:
| Version | Branch | Java Enterprise support | Spring versions | JAX-RS/ Jersey version | Struts support | Spark support |
|---|---|---|---|---|---|---|
| 1.x | 1.x | Java EE (javax.*) | 5.x (Boot 2.x) | 2.x | ✅ | ✅ |
| 2.x | 2.1.x | Jakarta EE 9-10 (jakarta.*) | 6.x (Boot 3.x) | 3.x | ❌ | ❌ |
| 3.x | main | Jakarta EE 11 (jakarta.*) | 7.x (Boot 4.x) | 3.x | ❌ | ❌ |

Below is the most basic AWS Lambda handler example that launches a Spring application. You can also take a look at the samples in this repository, our main wiki page includes a step-by-step guide on how to deploy the various sample applications using Maven and SAM.
publicclassStreamLambdaHandlerimplementsRequestStreamHandler {
privatestaticfinalSpringLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
static {
try {
handler = SpringLambdaContainerHandler.getAwsProxyHandler(PetStoreSpringAppConfig.class);
} catch (ContainerInitializationExceptione) {
// if we fail here. We re-throw the exception to force another cold starte.printStackTrace();
thrownewRuntimeException("Could not initialize Spring framework", e);
}
}
@OverridepublicvoidhandleRequest(InputStreaminputStream, OutputStreamoutputStream, Contextcontext)
throwsIOException {
handler.proxyStream(inputStream, outputStream, context);
}
