in28minutes/master-spring-and-spring-boot ? reverse-engineered prompt

Build me a beginner friendly Java learning project that walks through Spring and Spring Boot from the basics to a real app.

I want a small hands on codebase with examples for core Spring concepts, Spring Boot, JPA and Hibernate, a simple web app, a REST API, a full stack todo style app, plus separate examples for testing, security, Maven or Gradle, Docker, and AWS. Keep it practical and easy to follow, with clear starter code and working features I can run and explore.

Please make the app feel like a real tutorial project, not just toy snippets. Include a clean structure, sensible defaults, and enough implementation that I can see how the pieces fit together. If you need to check current Spring Boot or Spring Security docs online, go ahead and do that.
