Getting Started with Spring Boot

Spring Boot is what convinced me that Java could be as productive as the JavaScript frameworks I had been working in. Dependency injection and auto-configuration meant I could focus on application logic instead of wiring everything together by hand.

What I Learned

• Java Fundamentals — types, classes, interfaces, and generics as the foundation the framework builds on
• Dependency Injection — letting the container construct and supply collaborators instead of wiring them manually
• Auto-Configuration — how Spring Boot reduces boilerplate setup by configuring sensible defaults automatically
• REST Controllers — mapping endpoints with annotations, handling request bodies, and returning JSON responses
• Project Structure — organizing a backend into layers that stay maintainable as the application grows

Building Real Projects

Applying these ideas to backend services with Java and Spring Boot meant structuring a real application rather than a demo — exposing REST APIs, handling data between layers, and connecting that backend to a frontend interface.

Where I Am Now

Java and Spring Boot are my current focus for backend work. I understand how the framework assembles an application, which means I can build REST services, track down failures, and make architectural decisions with confidence.
