Spring Boot 3.x code generation for REST APIs, microservices, and reactive applications with built-in security and data access patterns. Load detailed guidance based on context: A standard Spring Boot feature consists of these layers. Use these as copy-paste starting points. Documentation - 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 - 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:...
