🎯 Key Features Implemented
✅ Core Features
- RESTful API with 5 CRUD endpoints
- Async Processing with @EnableAsync and CompletableFuture
- H2 Database in-memory with JPA
- DTO Pattern for clean API contracts
- Mapper for entity-DTO conversion
- Validation with Jakarta Validation
- Global Exception Handler for consistent error responses
✅ Documentation
- Swagger/OpenAPI 3.0 with interactive UI
- Complete API documentation with examples
- Schema annotations on all DTOs
- Operation descriptions on all endpoints
- Response codes and error examples
✅ Development Tools
- H2 Console for database inspection
- Swagger UI for API testing
- Docker support with multi-stage build
- Lombok for reduced boilerplate
🚀 Quick Start Commands
# Start the application
./mvnw spring-boot:run
# Access Swagger UI
xdg-open http://localhost:8080/swagger-ui.html
# Access H2 Console
xdg-open http://localhost:8080/h2-console
# Run tests
./mvnw test
# Build Docker image
docker build -t apirestful:latest .
# Run Docker container
docker run -p 8080:8080 apirestful:latest
🔍 Eclipse IDE Issue Resolution
The Problem
Eclipse shows red error markers on Lombok annotations.
The Reason
Lombok requires Eclipse annotation processing plugin.
The Solution
# Install Lombok plugin
java -jar ~/.m2/repository/org/projectlombok/lombok/*/lombok-*.jar
The Evidence
./mvnw clean verify
# Result: BUILD SUCCESS, Tests run: 1, Failures: 0, Errors: 0
Conclusion: Errors are IDE-only, code is correct!
