This is a Quarkus based application motivated by Google flights application. You can find details about the design in this Design doc.pdf.
- Modular Architecture: The project is structured into distinct modules ensuring strict separation of concerns:
fs-service: Core business logic and aggregation strategy.fs-warehouse: Data persistence and warehouse operations.fs-models: Shared domain models.fs-mock: Mock implementations for external dependencies.
- Event-Driven Architecture: Utilizes RabbitMQ for asynchronous, non-blocking communication between the scanning service and the warehouse service using the Publish-Subscribe pattern.
- Design Patterns: Extensively uses enterprise design patterns including:
- Strategy Pattern: For handling multiple airline providers (KLM, Lufthansa) interchangeably.
- Proxy Pattern: For wrapping external API clients with caching and messaging capabilities.
- Builder Pattern: For fluent and immutable object construction.
- Repository Pattern: For abstracting data access logic.
- Tech Stack: Built on Quarkus (Supersonic Subatomic Java) leveraging Jakarta EE standards (CDI, JAX-RS, JPA) and MicroProfile for cloud-native resilience and observability.
Build the Docker images by running the goal
clean install -DskipTests -P docker-build using the Maven
helper plugin: [https://plugins.jetbrains.com/plugin/7179-maven-helper](Maven Helper Plugin).
Now get the containers up with docker compose up -d and call the
GET request using the Postman collection Flight Scanner.postman_collection.json.
