SpringBoot Keycloak SPA application

This project was generated with Spring Initializr.

Follow along with the tutorial from Phase Two.

Get Started

Start Keycloak Server

To skip this section, use Phase Two to setup a free Keycloak hosted in the cloud. Instructions below assume using the local instance, but values can easily be changed to match the cloud instance.

  1. Start Keycloak server using docker-compose up -d
  2. Go to http://localhost:8888/auth and login using username admin and password admin
  3. Create a realm demo-realm
  4. Create a public client demo-spa and add redirectUri http://localhost:4200/* and Web Origins http://localhost:4200
  5. Create a realm role user
  6. Create a test user and assign the user role to it. Add password credentials to the test user.

Start Angular Application

  1. Open another terminal. Go to ./angularclient folder. Run npm i and start the Angular app using npm run start.
  2. Open the browser to http://localhost:4200/. After login the accessToken should be present in the localStorage of the browser. View this by opening a Web console and typing localStorage to view its value.
  3. Use access token to access secured endpoints:

Start Spring Application

  1. Run ./gradlew bootRun to start the SpringBoot application in a terminal.
  2. Directly hit the Spring application's API interface. Pull the accessToken from localStorage.
curl --location 'http://localhost:8080/api/test/anonymous' \
    --header 'Authorization: Bearer {{$access_token}}'

curl --location 'http://localhost:8080/api/test/user' \
    --header 'Authorization: Bearer {{$access_token}}'
