This is the Authorization Server for the KitchenSink application. It provides authentication and token generation using Spring Authorization Server with OAuth2 and PKCE.

• OAuth2 Authorization Code Flow with PKCE
• JWT-based authentication
• User authentication with MongoDB
• Role-based access control (Admin, Client)
• CORS support for frontend integration
• Docker support

• Java 21
• Spring Boot 3.x
• Spring Security OAuth2 Authorization Server
• MongoDB
• Docker

• Java 21
• Maven 3+
• MongoDB running on Docker
• Docker (if running in containers)

Ensure MongoDB is running and update application.properties with the correct database URL:

spring.data.mongodb.uri=mongodb://admin:adminpassword@localhost:27017/auth-db?authSource=admin

# Clone the repository
git clone <repo-url>
cd auth-server

# Build the project
mvn clean install

# Run the server
mvn spring-boot:run

# Build Docker Image
docker build -t auth-server .

# Run Container
docker run -p 9000:9000 --name auth-server auth-server

If using docker-compose.yml, start all services together:

docker-compose up -d

Run the AuthServerApplication.java file which will start the project on port 9000

Visit the following URL in your browser:

http://localhost:9000/oauth2/authorize?response_type=code&client_id=public-client-react-app&redirect_uri=http://localhost:3000/login/oauth2/code/public-client-react-app&scope=openid

After logging in, copy the code from the redirect URL.

Run the following curl command:

curl --location 'http://localhost:9000/oauth2/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'grant_type=authorization_code' \
--data-urlencode 'client_id=public-client-react-app' \
--data-urlencode 'redirect_uri=http://localhost:3000/login/oauth2/code/public-client-react-app' \
--data-urlencode 'code=<YOUR_AUTHORIZATION_CODE>'

This will return an access token that can be used for authentication.

Press CTRL + C

docker stop auth-server
docker rm auth-server

docker-compose down
