This repository contains example OAuth 2.0 resource servers built with Micronaut, Quarkus, Spring Boot, and Helidon.
Prerequisites: Java 20 with GraalVM and HTTPie.
First, clone this repository:
git clone https://github.com/oktadev/auth0-java-rest-api-examples.gitYou will need a JDK with GraalVM and its native-image compiler. Using SDKMAN, run the following command and set it as the default:
sdk install java 22.3.3.r20-grlNext, you'll need a free Auth0 developer account.
Install the Auth0 CLI and run auth0 login to connect it to your account.
Create an access token using Auth0's CLI:
auth0 test token -a https://<your-auth0-domain>/api/v2/Set the access token as a TOKEN environment variable in a terminal window.
TOKEN=eyJraWQiOiJYa2pXdjMzTDRBYU1ZSzNGM...Change the following files for each framework to match your Auth0 domain:
- Micronaut:
micronaut/src/main/resources/application.yml - Quarkus:
quarkus/src/main/resources/application.properties - Spring Boot:
spring-boot/src/main/resources/application.properties - Helidon:
helidon/src/main/resources/META-INF/microprofile-config.properties
You can start each app using its CLI, Gradle, or Maven. Note that you will only be able to start one at a time since they all run on port 8080.
- Micronaut:
./gradlew optimizedRun - Quarkus:
quarkus dev - Spring Boot:
./gradlew bootRun - Helidon:
helidon dev
Then, you can test them with an access token and HTTPie.
Use HTTPie to pass the JWT in as a bearer token in the Authorization header.
http :8080/hello Authorization:"Bearer $TOKEN"You should see your email address printed to your terminal.
You can also build and run each example as a native app.
- Micronaut:
./gradlew nativeOptimizedCompile - Quarkus:
quarkus build --native - Spring Boot:
./gradlew nativeCompile - Helidon:
mvn package -Pnative-image
Then, start each app as a native executable.
- Micronaut:
./build/native/nativeOptimizedCompile/app - Quarkus:
./build/quarkus-1.0.0-SNAPSHOT-runner - Spring Boot:
./build/native/nativeCompile/spring-boot - Helidon:
./target/helidon
