About This Skill

Spring Boot Service Builder generates production-ready Java microservices following Spring Boot 3 conventions and enterprise best practices. It handles the full service lifecycle from entity design through REST API exposure and deployment configuration.

Generated Project Structure

``` src/main/java/com/example/ controller/ service/ repository/ model/ entity/ dto/ config/ exception/ ```

Core Components

REST Controllers Generates `@RestController` classes with proper request mapping, request/response DTOs, Bean Validation (`@Valid`), and OpenAPI `@Operation` annotations for documentation.

JPA Layer - `@Entity` classes with proper relationship mappings (`@OneToMany`, `@ManyToMany`) - Spring Data JPA repositories with custom query methods - Flyway or Liquibase migration scripts - QueryDSL or Specification API for dynamic filtering

Spring Security - JWT-based stateless authentication - Method-level security with `@PreAuthorize` - CORS configuration for cross-origin requests - Password encoding with BCrypt

Observability - Actuator endpoints for health checks and metrics - Micrometer + Prometheus integration - Structured logging with Logback JSON encoder

Docker Support - Multi-stage `Dockerfile` with JRE 21 base - `docker-compose.yml` with PostgreSQL and the service

Use Cases

  • Building enterprise-grade REST APIs with Spring Boot 3
  • Implementing Spring Security with JWT or OAuth2
  • Creating JPA entities and repository patterns for relational databases
  • Generating Docker and Kubernetes deployment configurations

  • + OpenAPI documentation generated from annotations
  • + Docker-ready with multi-stage builds

Cons
