To install this example application, run the following commands:

git clone https://github.com/oktadeveloper/okta-spring-boot-kotlin-example.git

This will get a copy of the project locally.

To build the project, run the following command inside the project's folder:

./gradlew build

You will need to create an OIDC App in Okta to get a clientId and clientSecret.

Log in to your Okta Developer account (or sign up if you don’t have an account) and navigate to Applications > Add Application. Click Web, click Next, and give the app a name you’ll remember. Click Done and copy the clientId into server/src/main/resources/application.yml.

okta:  
  oauth2:  
    issuer: https://{yourOktaDomain}/oauth2/default  
    client-id: {yourClientID}
    client-secret: {yourClientSecret}

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

To start the application you can just run:

./gradlew bootRun

This example uses the Okta Spring Boot Starter to integrate with Okta.
