This example app shows how to create a Spring Boot API and display its data with a React UI.

Please read Bootiful Development with Spring Boot and React to see how this app was created.

Prerequisites: Java 8 and Node.js.

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 [email protected]:oktadeveloper/spring-boot-react-example.git
cd spring-boot-react-example

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, cd into the server folder and run:

./mvnw spring-boot:run

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

yarn && yarn start

The primary example (without authentication) is in the master branch, while the Okta integration is in the okta branch. To check out the Okta branch on your local machine, run the following command.

git checkout okta

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 Single-Page App, click Next, and give the app a name you’ll remember. Change all instances of localhost:8080 to localhost:3000 and click Done.

Set the issuer and copy the clientId into server/src/main/resources/application.properties.

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

okta.oauth2.issuer=https://{yourOktaDomain}.com/oauth2/default
okta.oauth2.clientId={clientId}

Set the issuer and copy the clientId into client/src/App.tsx.

const config = {
  issuer: 'https://{yourOktaDomain}.com/oauth2/default',
  redirectUri: window.location.origin + '/implicit/callback',
  clientId: '{clientId}'
};

This example uses the following libraries provided by Okta:

• Okta Spring Boot Starter
