spring-boot-best-practices

What problem does it solve?

Spring Boot, Kotlin, and WebFlux implementation patterns help teams write safer, maintainable, and scalable Spring-based services by enforcing clean architecture, idiomatic Kotlin, and reactive design.

Core Features & Use Cases

• Dependency Injection: prefer constructor injection for testability and immutability.
• Controller Design & DTOs: use idiomatic Kotlin data classes and clear separation between API layer and domain logic.
• Error Handling & Observability: consistent error handling via centralized advice and metrics instrumentation.
• Testing & Configuration: guidance on testing slices, configuration properties, and packaging structure for features.
• Use Case: apply these patterns when building a new Spring Boot microservice with Reactive endpoints.
