URL Shortener

This project is a URL shortener developed in Java using the Spring Boot framework. It allows you to create short URLs that redirect to long URLs, making link sharing and management easier.

Main Components

• Controller: Responsible for receiving HTTP requests and directing them to the appropriate service.
• ServiceProduto: Contains the business logic for shortening URLs and redirecting.
• Repository: Interface for persisting URL data.
• Model: Represents the URL entity in the system.
• Dto: Data transfer object between layers.

How It Works

1. The user sends a long URL to the system.
2. The system generates a short URL and stores the mapping in the database.
3. When accessing the short URL, the system redirects to the original URL.
