Features

• JWT Authentication
• Stateless session management
• Custom filters for request and response logging
• Secure endpoints with role-based access control

Endpoints

• POST /auth/login - Authenticate user and generate JWT token
• POST /auth/register - Register a new user
• GET /posts - Public endpoint accessible without authentication
• GET /error - Public endpoint for error handling
• GET /secure - Secure endpoint accessible only with valid JWT token

Dependencies

• Spring Boot Starter Web
• Spring Boot Starter Security
• Spring Boot Starter Data JPA
• Lombok
• Jakarta Servlet API
• Spring Web

Installation

Configuration

• Configure the database connection in application.properties.

Usage

1. Register a new user by sending a POST request to /auth/register with user details.
2. Authenticate the user by sending a POST request to /auth/login with credentials to receive a JWT token.
3. Use the JWT token to access secure endpoints by including it in the Authorization header as Bearer <token>.

Custom Filters

JwtAuthFilter

• Validates the JWT token and sets the authentication in the security context.
