Java Aws lambda, api gateway, mysql link

Hi

I need a cloudformation template and java code, which will include API Gateway -> java Lambda (which will call a HTTP API) and will return the response back,

This will also query the mysql db, and with secret storage (for password) .

If you can help build jenkins pipeline to deploy this easily via git for code changes in Java code , will be good,

This I need a sample code to save my time on research

Let me know, thanks
