Setting Up Spring Boot App with OpenID Connect (OIDC) Login in GitPod

Setting up Spring Boot App OpenID Connect (OIDC) Login in GitPod

In this article, we will discuss how to set up OpenID Connect (OIDC) login for a Spring Boot application in GitPod. We will be using the @oktadev/auth0-spring-boot-passkeys-demo GitHub repository as a reference.

What is OpenID Connect?

OpenID Connect (OIDC) is an identity layer on top of the OAuth 2.0 protocol. It allows clients to verify the identity of the end-user based on the authentication performed by an authorization server. OIDC provides a simple JSON-based API for developers to authenticate users and obtain basic profile information.

Why use OpenID Connect in Spring Boot App?

Using OpenID Connect in a Spring Boot application provides several benefits, including:

• Reduced development time and effort as you don't have to build your own authentication system.
• Improved security as the authentication is handled by a trusted third-party provider.
• Ease of integration with other applications and services that support OpenID Connect.

Setting up OpenID Connect in Spring Boot App in GitPod

To set up OpenID Connect in a Spring Boot application in GitPod, follow the steps below:

1. Create a new GitPod workspace by clicking on the "GitPod" button in the GitHub repository.
2. Open the application.yml file and add the following configuration:

   spring:
     security:
       oauth2:
         client:
           registration:
             okta:
               client-id: ${OKTA_CLIENT_ID}
               client-secret: ${OKTA_CLIENT_SECRET}
               issuer-uri: ${OKTA_ISSUER_URI}
               scope: openid,profile,email
               provider: okta
               redirect-uri: "{baseUrl}/login/oauth2/code/{registrationId}"
   

   Make sure to replace the placeholders with your Okta credentials.

3. Open the SecurityConfig.java file and add the following code:

   http.oauth2Login()
     .loginPage("/login")
     .defaultSuccessUrl("/")
     .permitAll();
   

4. Create an Okta developer account and set up a new application.
5. Add the following environment variables to your GitPod workspace:
   • OKTA_CLIENT_ID: The client ID of your Okta application.
   • OKTA_CLIENT_SECRET: The client secret of your Okta application.
   • OKTA_ISSUER_URI: The issuer URI of your Okta application.
6. Run the application by executing the following command:

   ./mvnw spring-boot:run
   

7. Access the application by clicking on the "Preview" button in the GitPod workspace.
