Java Serverless AWS Example

A Java + AWS serverless example app that shows how to create a Java REST endpoint on AWS and secure it with Okta and JWT.

Please read Serverless Java with Amazon Web Services to see how this example was created.

Prerequisites:

• Java 11
• HTTPie
• An Okta Developer Account
• An Amazon Web Services account with billing activated

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 + roles in any application.

Getting Started

To install this example application, run the following commands:

git clone https://github.com/oktadeveloper/okta-java-serverless-aws-example.git
cd okta-java-serverless-aws-example

This will get a copy of the project installed locally.

Create an OIDC App in Okta

You will need to create an OIDC application.

1. From the top menu, click on the Application button. Click the Add Application button.
2. Select application type Web.
3. Click Next.
4. Give the app a name. I named mine Okta Serverless Lambda.
5. Under Login redirect URIs, add a new URI: https://oidcdebugger.com/debug

The rest of the default values will work.

Click Done.

Leave the page open or take note of the Client ID. You'll need it in a bit when you generate a token.

Open src/main/resources/config.properties and fill in the correct value for okta.oauth.issuer using your Okta developer URI. It will look something like dev-123456.okta.com. You can find it by going to your Okta developer dashboard and, from the top menu, selecting API and Authorization servers. You want the Issuer URI for the default authorization server in the table.

okta.oauth.issuer=https://{yourOktaUrl}/oauth2/default
okta.oauth.audience=api://default
okta.oauth.connectionTimeoutSeconds=10
okta.oauth.readTimeoutSeconds=10

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

After modifying this file your app will be protected by Okta! See this repo's blog post to learn how to deploy this example on AWS Lambda.
