  Java Microservice Examples

  

You can find all the code shown in this tutorial on GitHub in the @oktadev/auth0-java-microservices-examples repository. The OpenFeign example with Spring MVC is in the spring-boot-gateway-mvc directory. The Spring Cloud Gateway with WebFlux is in spring-boot-gateway-webflux. The Keycloak example is in the keycloak branch.

• JHipster

  63 21,221 10.0 Java

  JHipster, much like Spring initializr, is a generator to create a boilerplate backend application, but also with an integrated front end implementation in React, Vue or Angular. In their own words, it "Is a development platform to quickly generate, develop, & deploy modern web applications & microservice architectures."

  

An easy way to get a pre-configured Keycloak instance is to use JHipster's jhipster-sample-app-oauth2 application. It gets updated with every JHipster release. You can clone it with the following command:

• Okta Spring Boot Starter

  4 312 8.8 Java

  Okta Spring Boot Starter

  

Okta also now has an Okta Spring Boot starter. I didn't use it in my first experiment, but I'm a big fan of it after the last few years! It dramatically simplifies configuration and makes securing your apps with OAuth 2.0 and OIDC easy. It's a thin wrapper around Spring Security's resource server, OAuth client, and OIDC features. Not only that, but it works with Okta Workforce Identity, Okta Customer Identity (aka Auth0), and even Keycloak.

• initializr

  258 3,344 8.9 Java

  A quickstart generator for Spring projects

  

I created all of these applications using start.spring.io's REST API and HTTPie.

• spring-cloud-gateway

  3 4,373 9.5 Java

  An API Gateway built on Spring Framework and Spring Boot providing routing and more.

  

Spring Cloud Gateway MVC 2023.0.0 doesn't allow you to configure a TokenRelay filter in YAML, so I added a RouterFunction bean to add it.

• SDKMan

  159 5,845 4.3 Gherkin

  The SDKMAN! Command Line Interface

  

To run the example, you must install the Auth0 CLI and create an Auth0 account. If you don't have an Auth0 account, sign up for free. I recommend using SDKMAN! to install Java 17+ and HTTPie for making HTTP requests.
