Spring_Boot_SpringSecurity_with_JWT_Auth

JWT Authentication is a backend project that focuses on implementing user authentication and authorization within the Spring Boot framework. The system exposes a RESTful API to handle user login and signup functionality, while incorporating robust security measures and JWT (JSON Web Tokens) for authentication.

Features

1. User signup: Users can create new accounts by providing their personal details, including name, email, and password. The system securely stores this user information in the H2 database.

2. User login: Users can authenticate themselves by providing their credentials (email and password) through the login endpoint. Upon successful authentication, the system generates and returns a web token.

3. JWT-based authentication: The application utilizes JSON Web Tokens (JWT) for user authentication and authorization. To access protected resources, a valid JWT token is required, ensuring that only authenticated users can access them.

Prerequisites Before running the application, ensure that you have the following installed:

• Java
• Java IDE (preferably Spring Tool Suite)

Setup & Installation

1. Install the Spring Tool Suite (STS) from https://spring.io/tools
2. Clone the Repository using the following command:

   git clone https://https://github.com/Subham-0922/Spring_Boot_SpringSecurity_with_JWT_Auth.git
   

3. Run Locally:
   • Open the "Backend_for_login_signup" folder with STS.
   • Go to "src/main/resources/application.properties" and update your SpringBoot username and password. By default, it uses "sa" as the username and an empty password for the in-memory store.
   • Change the server port by modifying "server.port=8080".
   • Go to "com.masai" package and run "BackendForLoginSignupApplication.java" as a Spring Boot App (Alt+Shift+X, B).

Access URLs Use Postman to interact with the following API endpoints:

1. Home (Method: GET):

   http://localhost:8080/user
   

2. User Signup (Method: POST):

   http://localhost:8080/user/signup
   

   Request Body:

   {
     "firstName": "fName",
     "lastName": "lName",
     "email": "email@example.com",
     "password": "@password"
   }
   
   

3. Admin Signup (Method: POST):

   http://localhost:8080/user/signup/{secretKey}
   

   Replace {secretKey} with the actual secret key value in the URL. Request Body:

   {
     "firstName": "fName",
     "lastName": "lName",
     "email": "email@example.com",
     "password": "@password"
   }
   
   

4. User Login (Method: GET):

   http://localhost:8080/user/userLogin
   

   Request Body:

   {
     "email": "email@example.com",
     "password": "@password"
   }
   
   

5. Admin Login (Method: GET):

   http://localhost:8080/user/adminLogin
   

   Request Body:

   {
     "email": "email@example.com",
     "password": "@password"
   }
   
   

Conclusion This backend project leverages Spring Boot to provide user authentication and authorization features, including user signup, login, and JWT-based authentication. The provided API endpoints enable interaction with different functionalities of the application.
