Fundamental Spring Boot: Keep it Simple, Get it Right, Be Productive and Have Fun!

" summary

Favor YAML for config, keep one file per environment and default to a local profile; convert properties into type-safe @ConfigurationProperties beans with validation instead of scattering @Value. Prefer constructor injection and leverage implicit constructor injection (or Lombok’s @RequiredArgsConstructor); avoid field injection. For startup work use CommandLineRunner or application events. Troubleshoot by enabling debug, tuning log levels, and querying Actuator endpoints (beans, conditions, configprops, env, mappings, loggers); use DevTools, Boot Dashboard and H2 console for fast local development.
