A guide similar to smithy-typescript - https://aws.amazon.com/blogs/devops/smithy-server-and-client-generator-for-typescript/
on how to -

• Model a simple REST service in Smithy
• Generate a Smithy server SDK for Java
• Implement a service in Lambda using the generated server SDK
• Deploy the service to AWS using the AWS CDK
• Generate a client SDK, and use it to call the deployed service

would be super helpful.
