# Spring Security Project with JWT

This project demonstrates how to implement authentication and authorization using Spring Security with JSON Web Tokens (JWT) in a Spring Boot 3 application.

## Features

- User registration and login endpoints
- JWT generation and validation
- Secure API endpoints using JWT
- Role-based authorization

## Technologies Used

- Spring Boot 3
- Spring Security
- JSON Web Tokens (JWT)
- Maven

## Getting Started


### Prerequisites

- Java Development Kit (JDK) 11 or higher
- Maven

### Installation

1. Clone the repository:

   ```bash
   git clone https://github.com/tamerlankayak/SpringSecurityJWT.git

2. Change to the project directory:

   cd spring-security-jwt

3. Build the application:

   mvn clean install

Configuration

1. Open the application.properties file located in the src/main/resources directory.

2. Modify the database configuration properties according to your setup. For example:

   spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase
   spring.datasource.username=db_user
   spring.datasource.password=db_password
   

3. Save the changes.

Usage

1. Run the application:

   mvn spring-boot:run

2. The application will start on http://localhost:8080.

3. Use a tool like Postman to interact with the API endpoints.

Note: To access the protected resource, include the JWT in the request header using the Authorization header with the value Bearer <JWT>, where <JWT> is the token obtained after successful authentication.
