Getting started

To install this example application, run the following commands:

git clone https://github.com/oktadeveloper/spring-boot-oauth-implicit-tutorial.git
cd spring-boot-oauth-implicit-tutorial

This will download a copy of the project.

Create an application in Okta

You will need to create an OpenID Connect application in Okta to to perform authentication.

Log in to your Okta Developer account (or sign up if you don’t have an account) and navigate to Applications > Add Application. Click Single-Page App, click Next, and give the app a name you'll remember. Change both the Base URI and Login redirect URI to http://localhost:8080 and click Done.

Server configuration

Set the issuer and client ID in src/main/resources/application.yml:

okta:
  oauth2:
    clientId: {clientId} # Okta app client ID
    issuer: https://{yourOktaDomain}.com/oauth2/default # update with your Okta domain name

Note: The value of {yourOktaDomain} should be something like dev-123456.oktapreview.com. Make sure you don't include -admin in the value!

./mvnw spring-boot:run
