# **Variate JDBC API**

![variate](https://github.com/user-attachments/assets/5309b3ad-4cef-41ca-bf11-70d5e441f00f)

**Variate JDBC API** is a Spring Boot-based e-commerce backend application that provides a RESTful API for managing categories, products, orders, order items, payments, and reviews. The application integrates with PostgreSQL as its primary database and supports JWT-based authentication for secure access.

## **Features**

- **Category Management**: Create, read, update, patch, and delete product categories.
- **Product Management**: Handle products under different categories, including information such as price, description, and stock availability.
- **Order Management**: Create, update, and manage customer orders.
- **Order Item Management**: Handle individual items within customer orders.
- **Payment Management**: Manage payment details related to customer orders.
- **Review Management**: Customers can add, update, and manage reviews for products.
- **JWT Authentication**: Secure API access using JSON Web Tokens (JWT).
- **Swagger Documentation**: Explore and interact with the API using Swagger UI.

## **Technologies Used**

- **Java 22**
- **Spring Boot 3.3.3**
- **JDBC** for direct database access and SQL queries
- **Spring Security** with JWT for authentication and authorization
- **PostgreSQL** as the primary database
- **H2** for in-memory testing
- **ModelMapper** for DTO conversions
- **Swagger/OpenAPI** for API documentation
- **Maven** for dependency management and build automation

## **Database Setup**

This project uses PostgreSQL as the database. The default configuration assumes a database named `variatespring`. Ensure PostgreSQL is installed and running in your local environment, and update the credentials in the `application.properties` file as needed.

Example `application.properties` configuration:

```properties
spring.datasource.url=jdbc:postgresql://localhost:5432/variatespring
spring.datasource.username=yourUsername
spring.datasource.password=yourPassword
```

## **Endpoints Overview**

### **Category Endpoints**

- `POST /api/categories`: Create a new category
- `GET /api/categories/{id}`: Retrieve a category by ID
- `GET /api/categories`: List all categories
- `PUT /api/categories/{id}`: Update a category by ID
- `PATCH /api/categories/{id}`: Partially update a category
- `DELETE /api/categories/{id}`: Delete a category

- `DELETE /api/products/{id}`: Delete a product

### **Order Endpoints**

- `POST /api/orders`: Create a new order
- `GET /api/orders/{id}`: Retrieve an order by ID
- `GET /api/orders`: List all orders
- `PUT /api/orders/{id}`: Update an order
- `PATCH /api/orders/{id}`: Partially update an order
- `DELETE /api/orders/{id}`: Delete an order

## **Security**

JWT-based authentication is used for securing the API. Publicly accessible endpoints include:

- `/api/auth/login`
- `/api/auth/register`
- `/swagger-ui/**`
- `/v3/api-docs/**`

All other endpoints require a valid JWT token to access.

## **API Documentation**

Explore the API using Swagger UI. You can access the interactive API documentation via the following links:

- **Swagger UI**: `http://localhost:8080/swagger-ui/index.html`
- **OpenAPI Docs**: `http://localhost:8080/v3/api-docs`

## **Running the Application**

```

3. Configure your PostgreSQL database credentials in `application.properties`.

4. Run the application using Maven:
