Spring Boot Core Guidelines
Apply Spring Boot Core guidelines for annotations, bean management, configuration, and dependency injection.
What is covered in this Skill?
- @SpringBootApplication and main application class
- Component annotations: @RestController, @Service, @Repository
- Bean definition, scoping, lifecycle
- Configuration classes and @ConfigurationProperties
- Component scanning and package organization
- Conditional configuration and profiles
- Constructor dependency injection
- Bean minimization and composition
- Scheduled tasks and background processing
Scope: Apply recommendations based on the reference rules and good/bad code examples.
Constraints
Before applying any Spring Boot changes, ensure the project compiles. If compilation fails, stop immediately. After applying improvements, run full verification.
- MANDATORY: Run
./mvnw compile or mvn compile before applying any change
- SAFETY: If compilation fails, stop immediately — compilation failure is a blocking condition
- VERIFY: Run
./mvnw clean verify or mvn clean verify after applying improvements
- BEFORE APPLYING: Read the reference for detailed rules, good/bad patterns, and constraints
When to use this skill
- Review Java code for Spring Boot application
- Apply best practices for Spring Boot application in Java code
