This project shows hot to use Jersey and Spring together in AWS Lambda using aws-serverless-java-container.
$ git clone git@github.com:seeebiii/lambda-jersey-spring-example.git
$ cd /path/to/repo
$ ./deploy.sh <BUCKET_NAME> [STACK_NAME]
- BUCKET_NAME: a S3 bucket name to upload the JAR file to, e.g.
[your-name]-lambdas - STACK_NAME: a name which identifies the stack you are creating with the CloudFormation template. Default: lambda-jersey-spring-example
Then just access the resources as printed in your output:
Test resource one at: https://xxx.execute-api.us-east-1.amazonaws.com/Prod/one
Test resource two at: https://xxx.execute-api.us-east-1.amazonaws.com/Prod/two
Take a look at JerseySpringHandler which contains the following important code:
public class JerseySpringHandler implements RequestHandler<AwsProxyRequest, AwsProxyResponse> {
private JerseyLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
public JerseySpringHandler() {
// create Spring context
AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
context.register(SpringConfig.class);
context.refresh();
// use Spring bean of JerseyResourceConfig to have spring supported resources
JerseyResourceConfig resourceConfig = context.getBean(JerseyResourceConfig.class);
handler = JerseyLambdaContainerHandler.getAwsProxyHandler(resourceConfig);
}
public AwsProxyResponse handleRequest(AwsProxyRequest awsProxyRequest, Context context) {
return handler.proxy(awsProxyRequest, context);
}
