description	Use this skill when configuring, structuring, or integrating Spring Boot components using native Spring Boot mechanisms without reimplementing existing functionality.

When applying Spring Boot Mastery:

1. Use Spring Boot 3.2.x with:

   • Auto-configuration enabled
   • Convention over configuration

2. Use official starters only:

   • spring-boot-starter-web
   • spring-boot-starter-security
   • spring-boot-starter-data-jpa
   • spring-boot-starter-validation
   • spring-boot-starter-actuator

3. Configuration rules:

   • All configuration via application.yml
   • Environment overrides via Docker env vars
   • No hardcoded configuration values

4. Bean management:

   • Prefer constructor injection
   • Avoid field injection
   • Keep configuration classes minimal

5. Profiles:

   • dev, test, prod profiles must exist
   • No profile-specific logic in code

Never bypass Spring Boot facilities with manual wiring unless absolutely required.
