Spring Boot Development

A solid reference for building Spring Boot applications with real code examples covering the fundamentals: auto-configuration mechanics, constructor-based dependency injection (which it rightly recommends over field injection), REST controller patterns with proper status codes and response handling, and the usual Spring Data and Security patterns you'd expect. The examples show actual implementation details like conditional beans, path variables, request mapping variations, and ResponseEntity patterns. Worth using when you need quick guidance on idiomatic Spring Boot practices or want to see how auto-configuration actually works under the hood. The code snippets are production-oriented, not toy examples, which makes it more useful than generic Spring tutorials.
