Spring Boot JWT Backend

A Spring Boot backend application that utilizes JWT (JSON Web Tokens) for authentication and authorization.

Overview

This project provides a robust backend setup with JWT authentication. Users can register, authenticate, and make API calls secured with JWT. All of the users are saved on a local postgresql server.

An API call to localhost:8080/api/v1/demo without JWT token:

An API call to localhost:8080/api/v1/demo with JWT token in the header:

Authorization: bearer eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJrcmluc0BlbWFpbC5jb20iLCJpYXQiOjE2OTI4OTY5OTMsImV4cCI6MTY5MzUwMTc5M30.Vuqr89siFnWeB3p4AO-epUtpODZ-PcCLjwlcqNOJ4Nw

To create a new account: Send a POST request to localhost:8080/api/v1/register with these in the body, and that will create an account and response with a token

{
  "firstname": "krins",
  "lastname": "krins",
  "email": "[email protected]",
  "password": "password"
} 

if you are already registered and you need a new token, you can make a POST request to localhost:8080/api/v1/authenticate with email and password in the body, and that should return with a new JWT token.

The payload of the jwt contains information about the email, expiration date and issue date

{
  "sub": "[email protected]",
  "iat": 1692896993,
  "exp": 1693501793
}
