thombergs/code-examples — reverse-engineered prompt

I want a learning repo full of small, self contained example projects that show how to use a bunch of common Java technologies in a practical way. Make it feel like code that could support blog posts or tutorials, with each example living in its own folder and being easy to open, run, and understand on its own.

Focus mostly on Java, especially Spring related topics like boot apps, data access, security, JWT, cloud, reactive work, and web APIs. It would also be great to include examples for testing, mocking, design patterns, resilience, GraphQL, HTTP clients, AWS related code, and a few Kotlin or Node examples where it makes sense. Keep the examples small and purposeful, not one giant app.

Please add short READMEs in the individual example folders explaining what each one demonstrates and how to run it. If something is unclear, look up current docs online and choose sensible defaults so the whole repo feels consistent and usable.
