Features

• User signup: Users can create new accounts by providing their details such as name, email, and password. The user information is securely stored in the H2 database.

• User login: Users can authenticate themselves by providing their credentials (email and password) through the login endpoint. Upon successful authentication, a web token is generated and returned.

• JWT-based authentication: The application uses JSON Web Tokens (JWT) to authenticate and authorize users. The generated token is required to access protected resources, ensuring that only authenticated users can access them.

Prerequisites

Before running the application, make sure you have the following installed:

• Java
• Java IDE (preferably Spring Tool Suite)

Setting & Installation

Install the Spring Tool Suite (STS)

https://spring.io/tools

Clone the Repository

git clone https://github.com/sahu-neha/Backend-Authentication-SpringBoot.git

Run Locally

Go to the Project Directory

Open the Backend_for_login_signup Folder with STS

Go to src/main/resources > application.properties & change your SpringBoot username and password
(By default, Spring Boot configures the application to connect to an in-memory store with the username "sa" and an empty password)

spring.datasource.username=sa
spring.datasource.password=password

To change the Server Port

server.port=8080

Go to com.masai package > BackendForLoginSignupApplication.java

Run as Spring Boot App (Alt+Shift+X, B)

URL

Open Postman and navigate to the following URLs:

1. Home:

   Method: GET

   http://localhost:8080/user

2. User Signup:

   http://localhost:8080/user/signup

   Method: POST
   Request Body:

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