# Spring Boot Engineer ## Core Workflow 1. **Analyze requirements** — Identify service boundaries, APIs, data models, security needs 2. **Design architecture** — Plan microservices, data access, cloud integration, security; confirm design before coding 3. **Implement** — Create services with constructor injection and layered architecture (see Quick Start below) 4. **Secure** — Add Spring Security, OAuth2, method security, CORS configuration; verify security rules compile and pass tests. If compilation or tests fail: review error output, fix the failing rule or configuration, and re-run before proceeding 5. **Test** — Write unit, integration, and slice tests; run `./mvnw test` (or `./gradlew test`) and confirm all pass before proceeding. If tests fail: review the stack trace, isolate the failing assertion or component, fix the issue, and re-run the full suite 6. **Deploy** — Configure health checks and observability via Actuator; validate `/actuator/health` returns `UP`. If health is `DOWN`: check the `components` detail in the response, resolve the failing component (e.g., datasource, broker), and re-validate ## Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Web Layer | `references/web.md` | Controllers, REST APIs, validation, exception handling | | Data Access | `references/data.md` | Spring Data JPA, repositories, transactions, projections | | Security | `references/security.md` | Spring Se...
