The Car Rental System is a Spring Boot–based web application that provides an easy and efficient platform for renting luxury cars.
It offers both customer and admin interfaces, built using Java (Spring Boot), HTML, and CSS, and implements multiple design patterns to ensure scalability and clean architecture.
- Provide a user-friendly interface for renting cars.
- Enable real-time operations with no booking conflicts.
- Support database integration for data persistence.
- Simplify admin operations like adding, removing, or updating vehicles.
| Category | Tools / Frameworks |
|---|---|
| Frontend | HTML, CSS |
| Backend | Java (Spring Boot) |
| IDE | IntelliJ IDEA |
| Diagram Tools | SmartDraw, Rational Rose |
| Database | H2 / MySQL (Spring Boot Integration) |
Used in Spring Boot for managing service and component instances through dependency injection using @Autowired.
Used to construct RentalOrder objects step-by-step for cleaner object creation.
Implements CarFactory to create cars for different companies dynamically and populate the database.
Executioninterface defines commands.CommandExecutorexecutes valid commands or uses aNullCommandif no match is found.
Implemented in AdminCommandMediator, observing changes made by the admin in entities such as cars or customers.
Connects incompatible interfaces PriceSetter and Calculator via CostCalculator adapter.
AdminCommandMediator centralizes communication between command classes and controllers, reducing coupling.
Used in AdminController to handle cost-setting operations between multiple PriceSetter classes.
| Actor | Functionality |
|---|---|
| Customer | Place rental order, get order details, make payments |
| Admin | Add, remove, edit cars in the database |
| System | Store and manage all rental data efficiently |
