Spring Boot auto-configuration and declarative AI services for LangChain4j integration. \n \n Provides property-based configuration for multiple AI providers (OpenAI, Azure, Ollama) with Spring Boot starters and automatic bean wiring \n Enables interface-based AI service definitions using @AiService annotations combined with message templates and Spring dependency injection \n Supports RAG systems through configurable embedding stores (pgvector, Neo4j, Pinecone) and document ingestion pipelines

Distributed transaction management across microservices using choreography or orchestration patterns. \n \n Supports two saga approaches: choreography-based (event-driven, decoupled) and orchestration-based (centralized coordinator with easier tracking) \n Requires compensating transactions for every forward operation to ensure rollback capability and eventual consistency \n Integrates with Spring Boot 3.x, Kafka, RabbitMQ, and frameworks like Axon Framework, Eventuate Tram, and Camunda \n Empha

Event-Driven Architecture patterns for Spring Boot using domain events, transactional listeners, and Kafka messaging. \n \n Covers domain event design, ApplicationEventPublisher integration, and @TransactionalEventListener configuration for local event handling with AFTER_COMMIT phase guarantees \n Supports distributed messaging via Kafka and Spring Cloud Stream for inter-service communication with functional consumer beans \n Implements the transactional outbox pattern for reliable event publis

Constructor-first dependency injection patterns for Spring Boot with optional collaborator handling and bean selection strategies. \n \n Prioritizes constructor injection to keep dependencies explicit, immutable, and testable without Spring context. \n Handles optional dependencies through guarded setters, ObjectProvider, and deterministic no-op defaults. \n Resolves bean ambiguity using @Primary, @Qualifier, profiles, and conditional annotations (@ConditionalOnProperty, @ConditionalOnMissingBea

Feature-aligned CRUD services for Spring Boot 3 with layered architecture and Spring Data JPA. \n \n Establishes feature packages with domain, application, presentation, and infrastructure layers to maintain architectural boundaries and DDD principles. \n Covers complete CRUD workflows: entity modeling with invariants, repository interfaces, JPA adapters, transactional services, DTO records, and REST controllers with proper HTTP status codes. \n Includes validation patterns using jakarta.validat

Generates a fully configured Spring Boot project from scratch using the Spring Initializr API. The skill walks the user through selecting project parameters, choosing an architecture style (DDD or Layered), configuring data stores, and setting up Docker Compose for local development. The result is a build-ready project with standardized structure, dependency management, and configuration.

Production-ready Spring Boot applications with REST APIs, security, data access, and monitoring. \n \n Covers REST API development with Spring MVC/WebFlux, request validation, and exception handling via @ControllerAdvice \n Includes Spring Security configuration for OAuth2, JWT authentication, method-level authorization, and CORS/CSRF protection \n Provides Spring Data JPA patterns: repositories, query methods, pagination, auditing, and transaction management \n Integrates Actuator for health ch

Generate a Spring Boot 3.4.5 project skeleton with PostgreSQL, Redis, MongoDB, and Docker Compose. \n \n Scaffolds a Maven-based Spring Boot project with Java 21, including Lombok, Spring Data JPA, Spring Web, caching, and validation dependencies \n Pre-configures application.properties with connection details for PostgreSQL, Redis, and MongoDB, plus SpringDoc OpenAPI for API documentation \n Generates a docker-compose.yaml file with Redis 6, PostgreSQL 17, and MongoDB 8 services, each with pers

Spring Boot 3.x code generation for REST APIs, microservices, and reactive applications with built-in security and data access patterns. \n \n Generates layered Spring Boot 3.x applications with constructor injection, Spring Data JPA repositories, REST controllers, and global exception handling \n Implements Spring Security 6 authentication flows, OAuth2, JWT, and method-level security with CORS configuration \n Supports reactive WebFlux endpoints alongside traditional blocking REST APIs and Spr

Generate a Spring Boot Kotlin project skeleton with pre-configured databases and development services. \n \n Downloads a Spring Boot 3.4.5 project template with Kotlin, WebFlux, R2DBC, Redis, and MongoDB dependencies via Spring Initializr \n Includes Docker Compose configuration for PostgreSQL 17, Redis 6, and MongoDB 8 with pre-set credentials and volume mounts \n Adds SpringDoc OpenAPI integration for Swagger UI documentation and ArchUnit for architecture testing \n Requires Java 21, Docker, a
