Real-Time Event Ticketing System

Introduction

The Real-Time Event Ticketing System is designed to handle concurrent ticket releases and purchases by multiple vendors and customers. It features a Command-Line Interface (CLI), a web-based frontend (using React.js), and a backend developed with Spring Boot. The system ensures thread-safe interactions using multi-threading and synchronization mechanisms.

Features

• Frontend: A React-based UI that allows users to configure the system, manage vendors and customers, and view ticket availability in real-time.

• Backend: A Spring Boot REST API managing ticket operations, configuration, and synchronization.

• CLI: A console-based interface for configuring and simulating ticket release and retrieval by vendors and customers.

Setup Instructions

Ensure the following software is installed:

• Java : JDK 17 , Node.js : Version 18 , MySQL : Version 9.1 , NPM: Included with Node.js , Spring Boot: Included in the project

Backend Setup

1. Clone the project repository: git clone

2. Navigate to the backend folder: cd ticket-system-backend

3. Configure the database: Update the application.properties file in src/main/resources with your MySQL credentials:

spring.datasource.url=jdbc:mysql://localhost:3306/ticket_system spring.datasource.username= spring.datasource.password= spring.jpa.hibernate.ddl-auto=Update

4. Build and run the backend: ./mvnw spring-boot:run

5. Verify the backend is running:

• Access http://localhost:8080/api/health in your browser or Postman.
• Expected response: "Application is running."

Frontend Setup

1. Navigate to the frontend folder: cd ticketing-system-frontend

2. Install dependencies: npm install

3. Start the development server: npm start

4. Open the application in your browser at: http://localhost:3006

CLI setup

1. Navigate to the CLI folder: cd ticketing-system-cli

2. Compile the Java files: javac *.java

3. Run the system: java Main

Usage Instructions

Configuring the System

1. Frontend:

• Enter values for total tickets, ticket release rate, customer retrieval rate, and maximum ticket capacity.
• Click Submit to save the configuration.

2. CLI:

• Follow the prompts to input configuration values.

Managing Vendors and Customers

• Add vendors and customers through the frontend UI.
• In the CLI, vendors and customers are simulated concurrently.

Viewing Ticket Information

• The frontend displays the number of retrieved and available tickets in real-time using a progress bar

UI Controls

• Submit Button: Configures the system.
• Add Vendors/Customers: Adds participants to the system.
• Start/Stop Buttons: Starts or stops ticket transactions.
• Log Display: Displays real-time logs of system operations.

Testing the System

Backend

1. Use Postman or Curl to test API endpoints:

• Configure the system: POST /api/configuration/setup
• View tickets: GET /api/tickets

2. Verify database entries in the configuration andticketstables.

Frontend

• Interact with the UI and verify operations.

CLI

• Run different scenarios to test concurrency:
• Multiple vendors releasing tickets.
• Customers retrieving tickets concurrently
