Getting Started

To install this example application, run the following commands:

git clone https://github.com/oktadev/okta-spring-boot-react-crud-example.git spring-react
cd spring-react

This will get a copy of the project installed locally. To install all of its dependencies and start each app, follow the instructions below.

To run the server, run:

./mvnw spring-boot:run

To run the client, cd into the app folder and run:

npm i && npm start

Create an Application in Okta

Before you begin, you'll need a free Okta developer account. Install the Okta CLI and run okta register to sign up for a new account. If you already have an account, run okta login.

Then, run okta apps create. Select the default app name, or change it as you see fit. Choose Web and press Enter.

Select Okta Spring Boot Starter. Accept the default Redirect URI of http://localhost:8080/login/oauth2/code/okta and use http://localhost:3000,http://localhost:8080 for the Logout Redirect URI.

The Okta CLI will create an OIDC Web App in your Okta Org. It will add the redirect URIs you specified and grant access to the Everyone group. You will see output like the following when it's finished:

Okta application configuration has been written to:
  /path/to/app/src/main/resources/application.properties

Open src/main/resources/application.properties to see the issuer and credentials for your app.

okta.oauth2.issuer=https://dev-133337.okta.com/oauth2/default
okta.oauth2.client-id=0oab8eb55Kb9jdMIr5d6
okta.oauth2.client-secret=NEVER-SHOW-SECRETS

NOTE: You can also use the Okta Admin Console to create your app. See Create a Spring Boot App for more information.

Run ./mvnw spring-boot:run -Pprod and log in to your app at http://localhost:8080.
