This project demonstrates a comprehensive implementation of JWT (JSON Web Token) based authentication in a Spring Boot application. The project is structured with multiple components to handle various aspects of the application, ensuring clean and maintainable code.


Project Structure


* Entity: Defines the data model and maps it to the database.

* DTO (Data Transfer Object): Facilitates the transfer of data between different layers of the application.

* Repository: Handles all database operations and data persistence.

* Service: Contains the business logic and interacts with the Repository layer.

* Config: Configures security settings, including JWT authentication and authorization.

* Controller: Manages incoming HTTP requests, processes them, and returns appropriate responses.

* Util: Contains utility classes for various operations, particularly for handling JWT tokens.

Features


* JWT Generation: Generates JWT tokens upon successful authentication, which are then used for securing subsequent requests.

* User Authentication: Validates user credentials and issues JWT tokens, ensuring secure access to protected resources.

Technologies Used


* Spring Boot: Framework to create standalone, production-grade Spring-based applications.

* Spring Security: Provides authentication and authorization support, securing the application.

* JSON Web Token (JWT): Mechanism for securely transmitting information between parties as a JSON object.

* JPA/Hibernate: ORM (Object Relational Mapping) framework to interact with the database.

* MySQL (or any other database): Relational database for storing application data.

* Maven: Build automation tool for managing project dependencies.

Getting Started

Prerequisites


* JDK 17 or later: Ensure that your system is running Java Development Kit 17 or a later version.

* Maven 3.6 or later: Maven is required to manage dependencies and build the project.

* MySQL (or any other database): A database to store application data.

* IDE: Use an Integrated Development Environment like IntelliJ IDEA or Eclipse for development.

Installation and Setup

Clone the Repository:


    git clone https://github.com/sandundil2002/JWT-Authentication.git

    cd JWT-Authentication

Configure the Database:


* Update the application.properties file with your database connection details.

      spring.application.name=JWT-Authentication

      spring.datasource.url = jdbc:mysql://localhost:3306/yourDatabaseName?createDatabaseIfNotExist=true&allowPublicKeyRetrieval=true&useSSL=false

      spring.datasource.username=yourDatabaseUsername

      spring.datasource.password = yourDatabasePassword

      spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL8Dialect

      spring.jpa.hibernate.ddl-auto = update

      spring.datasource.driver-class-name =com.mysql.cj.jdbc.Driver

      spring.jpa.open-in-view=false

      spring.jpa.show-sql= true

      jwt.secret=e#s$p%o$r^t9

Build the Project:


    mvn clean install

Run the Application:


    mvn spring-boot:run

Access the Application:


* The application will be available at http://localhost:8080.
