# EVM Wheels — Car Rental Management

A Spring Boot 3 + Thymeleaf + PostgreSQL web app for managing a self-drive car rental business.

## Features

- **Public site** — landing page with hero, search bar, and featured cars
- **Browse & detail** — `/cars` (with optional date-range availability filter) and `/cars/{id}`
- **Auth** — username/password registration & login (Spring Security + BCrypt)
- **Customer flow** — book a car, view your bookings at `/my-bookings`
- **Admin panel** — `/admin` dashboard, full CRUD for cars, manage all bookings & update status
- **Date-range conflict detection** — prevents double-booking the same car

## Stack

| Layer    | Choice                         |
|----------|--------------------------------|
| Runtime  | Java 17, Spring Boot 3.3       |
| Web      | Spring MVC + Thymeleaf         |
| Data     | Spring Data JPA + Hibernate    |
| DB       | PostgreSQL                     |
| Security | Spring Security 6 + BCrypt     |
| Build    | Maven                          |

## Prerequisites

- JDK 17+
- Maven 3.9+
- PostgreSQL 13+ running locally

## Database setup

```sql
CREATE DATABASE evm_wheels;
```

By default the app connects with `postgres` / `postgres` on `localhost:5432/evm_wheels`. Override via env vars or by editing [src/main/resources/application.properties](src/main/resources/application.properties):

```bash
export DB_URL=jdbc:postgresql://localhost:5432/evm_wheels
export DB_USER=postgres
export DB_PASSWORD=postgres
```

Hibernate's `ddl-auto=update` creates the schema on first run, and `data.sql` seeds 6 demo cars. Users are seeded from [DataInitializer.java](src/main/java/com/evmwheels/carrental/config/DataInitializer.java) using the real password encoder.

## Run

```bash
mvn spring-boot:run
```

Then open <http://localhost:8080>.

## Seeded accounts

| Role     | Username | Password   |
|----------|----------|------------|
| Admin    | `admin`  | `admin123` |
| Customer | `demo`   | `demo1234` |

Change these immediately if you deploy this anywhere real.
