JWT Authentication with Spring Boot’s inbuilt OAuth2 Resource Server

This repo hosts the source code corresponding to the article JWT Authentication with Spring Boot’s inbuilt OAuth2 Resource Server.

This example project demonstrates the usage of Spring Boot OAuth2 Resource Server with JWT configuration to protect a REST API with JWT based authentication.

Furthermore, provides a "/login" endpoint to generate and issue JWTs upon successful login by the users.

This approach is ideal to be used as the backend for a single page application (SPA) written using a frontend framework like ReactJS, Angular, etc...

Solution Overview

Getting Started

• Use mvn clean install in the project root directory to build the project.
• Run the main class, com.example.springboot.jwt.JwtApplication to start the application.

Endpoints

• /login -> Public endpoint which returns a signed JWT for valid user credentials (username/password)
• /user -> A protected endpoint which returns the user details of the requesting user.
