The JWT-Authentication project aims to provide a secure authentication and authorization solution using Spring Security, JSON Web Tokens (JWT), and MySQL. It serves as a practical example of how to implement robust token-based authentication and role-based authorization for applications.

1. Token-Based Authentication:

   • Secure user authentication using JWT tokens.
   • When a user logs in, the server generates a JWT token containing user information and roles. Subsequent requests to protected endpoints require this token for authorization.

2. Role-Based Authorization:

   • Define roles (e.g., user, admin) and restrict access to specific endpoints based on these roles.
   • For example, an admin might have access to additional management endpoints compared to regular users.

3. Spring Security Integration:

   • Utilize Spring Security features for enhanced security.
   • Configure authentication providers, access control rules, and custom filters.

4. MySQL Database Integration:

   • Store user information and tokens in a MySQL database.
   • The database schema includes tables for users, roles, and tokens.

1. Clone the Repository:

   • Start by cloning this repository to your local machine:

     git clone https://github.com/shivamverma26/JWT-Authentication.git

2. Database Configuration:

   • Set up your MySQL database and configure the connection details in application.properties.
   • Create the necessary tables (users, roles, etc.) using database migration tools (e.g., Flyway, Liquibase).

3. Build and Run:

   • Build and run the project using Maven:

     cd JWT-Authentication
     ./mvnw spring-boot:run

1. Register a User Account:

   • Use the provided endpoints to create a new user account.
   • Example: POST /api/register

2. Authentication:

   • Authenticate and obtain an access token.
   • Send a POST request to /api/authenticate with valid credentials (username and password).
   • The server responds with a JWT token.

3. Access Protected Resources:

   • Use the obtained token to access protected resources.
   • Include the token in the Authorization header of subsequent requests.
   • Example: GET /api/profile

• Database Configuration:

  • Update the application.properties file with your MySQL database details.
  • Customize other settings related to database connections and pooling.

• Security Configuration:

  • Customize security settings in SecurityConfig.java.
  • Define access rules, authentication providers, and other security-related configurations.

• Register User:

  • POST /api/register: Create a new user account.
  • Provide user details (username, password, etc.).

• Authentication:

  • POST /api/authenticate: Authenticate and obtain an access token.
  • Requires valid user credentials.

• Protected Resource:

  • Example: GET /api/profile
  • Requires a valid JWT token with appropriate roles (e.g., user, admin).
