This example is a resource server using Spring Boot and Spring Data JPA. It also implements group-based authorization using Okta and OAuth 2.0.

Please read Build a Basic App with Spring Boot and JPA using PostgreSQL to see how this app was created.

Prerequisites: Java 8.

Okta has Authentication and User Management APIs that reduce development time with instant-on, scalable user infrastructure. Okta's intuitive API and expert support make it easy for developers to authenticate, manage, and secure users and roles in any application.

To install this example application, run the following commands:

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

This will get a copy of the project installed locally. To install all of its dependencies and start the app, run:

./gradlew bootRun

This will likely fail. You need to configure a PostgreSQL database with the following settings for everything to work out-of-the-box.

url: "jdbc:postgresql://localhost:5432/springbootjpa"
username: oktatutorial
password: abcd1234

You will need to create an OpenID Connect Application in Okta to get your values 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 SPA, click Next, and give the app a name you’ll remember. Click Done and copy the clientId into src/main/resources/application.yml.

okta:  
  oauth2: 
    issuer: https://{yourOktaDomain}/oauth2/default  
    clientId: {yourClientId}  
    scope: openid profile email
    rolesClaim: groups   

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

After modifying this file, restart your app and you should be able to authenticate with Okta.

This example uses Okta's Spring Boot Starter.
