Ticket Monster

A ticket purchase system with Spring Modulith based on Domain-Driven Design (DDD) principles.

Features

  1. Domain-Driven Design (DDD): The codebase is designed following DDD principles, ensuring maintainability and scalability.
  2. Authentication: Secures the system using Spring Security, implementing JWT and the * OAuth2 PKCE* approach.
  3. Lock Mechanism: Uses Spring Data JPA for CRUD operations and implements **locking mechanisms ** to ensure data consistency and prevent race conditions in ticket operations.
  4. Java Util Concurrency (JUC) for Handling Concurrency: Leverages Java's concurrency utilities to manage high-volume ticket operations effectively.
  5. Pub/Sub Mechanism for Multiple Instances: Employs Spring Kafka to broadcast ticket status updates across multiple instances for real-time synchronization.
  6. WebSocket: Enables real-time communication and updates to clients via WebSocket connections.
