Spring Boot Patterns

This one gives Claude the Spring Boot patterns you actually want: versioned REST endpoints, constructor injection with Lombok, proper service/repository layers, and DTOs that don't leak your entities. It handles the stuff that matters like transaction boundaries (read-only by default, write when needed), MapStruct for clean conversions, and a global exception handler that returns proper status codes. The examples show real structure decisions, not toy code. Use it when you're scaffolding controllers or need to remember whether existsById is actually better than findById for checks. It won't teach you Spring Boot from scratch, but it'll keep your codebase from turning into a mess of business logic in controllers and entities flying around as JSON.
