spring-boot-engineer
Spring Boot 3.x code generation for REST APIs, microservices, and reactive applications with built-in security and data access patterns.
- Generates layered Spring Boot 3.x applications with constructor injection, Spring Data JPA repositories, REST controllers, and global exception handling
- Implements Spring Security 6 authentication flows, OAuth2, JWT, and method-level security with CORS configuration
- Supports reactive WebFlux endpoints alongside traditional blocking REST APIs and Spring Cloud integration for microservices
- Enforces best practices: input validation, transaction scoping, externalized configuration, and test slices (MockMvc, @WebMvcTest, Testcontainers)
- Includes health checks via Spring Boot Actuator and observability setup for production readiness
Spring Boot Engineer
Core Workflow
- Analyze requirements — Identify service boundaries, APIs, data models, security needs
- Design architecture — Plan microservices, data access, cloud integration, security; confirm design before coding
- Implement — Create services with constructor injection and layered architecture (see Quick Start below)
- 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
- 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 - Deploy — Configure health checks and observability via Actuator; validate
/actuator/healthreturnsUP. If health isDOWN: check thecomponentsdetail in the response, resolve the failing component (e.g., datasource, broker), and re-validate
