Spring Boot Coding Guidelines

IMPORTANT: This skill covers Spring Boot framework patterns. For core Java language, see java-coding/.

Quick Start Checklist

Before writing Spring Boot code:

• Use constructor injection (never @Autowired on fields)
• Add @Transactional(readOnly = true) on service class
• Configure open-in-view: false in application.yml
• Use @Valid on request bodies
• Handle LazyInitializationException with JOIN FETCH
• Never expose stack traces in production
