> this project demonstrates how to encrypt passwords, authenticate users, and protect endpoints with minimal configuration.
🚀 Features
- ✅ User registration with BCrypt password hashing
- 🔐 Basic Authentication for protected endpoints
- 🧼 Stateless session management (`SessionCreationPolicy.STATELESS`)
- 🗃️ PostgreSQL integration via Spring Data JPA
- 🧠 Clean architecture with service, controller, and entity layers
- 🧪 Tested using Postman
🛠️ Tech Stack
- Java 17
- Spring Boot 3.5
- Spring Security
- Spring Data JPA
- PostgreSQL
- Lombok
📂 Endpoints
| Method | Endpoint | Description | Auth Required |
|--------|--------------|----------------------------------|---------------|
| POST | `/register` | Register a new user | ❌ No |
| GET | `/greet` | Greet user by username | ✅ Yes |
⚙️ Setup Instructions
1. Clone the repo
2. Create `application.properties` with your DB credentials
