PAPPURAJ / JWTauth

Creating a README file for JWT (JSON Web Tokens) in a Spring Boot application can help provide clear documentation for developers who are working on or with your project. Here's a basic template for a README file that covers JWT implementation in a Spring Boot application:

JWT Authentication in Spring Boot

This repository contains a Spring Boot application with JWT authentication. JSON Web Tokens (JWT) are a popular way to secure RESTful APIs, and this project demonstrates how to implement JWT authentication in a Spring Boot application.

Prerequisites

Before you start, make sure you have the following prerequisites installed on your system:

• Java 8 or higher
• Spring Boot
• Maven (or Gradle if you prefer)
• IDE (e.g., IntelliJ IDEA, Eclipse, or Visual Studio Code)
• Postman or a similar tool for testing APIs

Getting Started

1. Clone this repository to your local machine:

   git clone https://github.com/your-username/your-jwt-spring-boot.git

2. Open the project in your preferred IDE.

3. Build and run the application.

   mvn spring-boot:run

   The application should now be running on http://localhost:8080.

Configuration

The JWT configuration can be found in the application.properties file. You can customize JWT-related settings such as the secret key, token expiration time, and more in this file.

# JWT Configuration
jwt.secret=your-secret-key
jwt.expiration=3600

Usage

To use this JWT authentication in your own Spring Boot project, you can follow these steps:

1. Copy the JWT-related classes and configurations from this project into your project.

2. Customize the JWT configuration in application.properties according to your requirements.

3. Implement user authentication and authorization logic in your application.

4. Use the provided endpoints to generate and validate JWT tokens.
