Ticketing System Backend

This is the backend for the Ticketing System simulation project. It is built with Spring Boot and provides RESTful APIs for managing ticketing operations, including simulation start, status checks, and termination. The backend interacts with a frontend built using React.

---

Features

• Configure simulation parameters (total tickets, release rate, retrieval rate, etc.)
• Manage vendors and customers during the ticketing simulation
• Provide real-time status of the simulation via APIs
• Support for starting and stopping simulations

Prerequisites

1. Java Development Kit (JDK): Version 11 or higher.
2. Maven: For building and running the application.
3. Spring Boot: Embedded in the project via Maven dependencies.
4. Postman or any API testing tool (optional, for testing APIs).

Navigate to the project directory: cd ticketing-system-backend

Build the project: mvn clean install

Run the application: mvn spring-boot:run

The server will be available at: http://localhost:8080

API Endpoints Base URL: http://localhost:8080/api/tickets Start Simulation Endpoint: /startSimulation Method: POST Request Body: { "totalTickets": 100, "ticketReleaseRate": 5, "customerRetrievalRate": 2, "maxTicketCapacity": 50 } Description: Starts the ticketing simulation with the given configuration.

Check Status Endpoint: /status Method: GET Response: { "status": "Running", "ticketsRemaining": 40 } Description: Fetches the current status of the simulation. Stop Simulation Endpoint: /stopSimulation Method: POST Description: Stops the simulation and terminates all threads.

Technologies Used Java: Core programming language Spring Boot: Backend framework Maven: Build automation tool REST APIs: For frontend-backend communication

How to Test Use Postman or cURL to send HTTP requests to the provided endpoints. Example cURL request to start the simulation:

curl -X POST -H "Content-Type: application/json" -d '{ "totalTickets": 100, "ticketReleaseRate": 5, "customerRetrievalRate": 2, "maxTicketCapacity": 50 }' http://localhost:8080/api/tickets/startSimulation

Future Enhancements Add database integration for persistent storage of tickets and configurations. Implement more detailed logging and monitoring. Enhance error handling for invalid inputs and unexpected scenarios.
