Camunda Platform Runtime Quarkus Example

This example uses Quarkus, the Supersonic Subatomic Java Framework, in combination with the extension camunda-bpm-quarkus-engine.

It demonstrates how you can use the Camunda Platform Runtime Engine in combination with Quarkus to spawn a node that:

• Connects to an H2 on-disk database.
• Configures and bootstraps a process engine.
• Exposes two REST endpoints which:
  • Deploy the process.bpmn.
  • Start a process instance that calls the MyServiceDelegate bean.

You can:

1. Go to http://localhost:8080/deploy-process to deploy the provided BPMN process.
2. Go to http://localhost:8080/start-process to start a process instance of the deployed BPMN process.
3. Observe the console and watch out for the following log output:

   2021-08-05 16:58:39,286 INFO  [org.cam.bpm.qua.exa.MyServiceDelegate] (executor-thread-0) Hurray! MyService has been called!

Requirements

• Java 11+
• Maven 3.8.1+

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

mvn clean compile quarkus:dev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.

Packaging and running the application

The application can be packaged using:

mvn clean package

It produces the quarkus-run.jar file in the target/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/quarkus-app/lib/ directory.

If you want to build an über-jar, execute the following command:

mvn clean package -Dquarkus.package.type=uber-jar

The application is now runnable using java -jar target/camunda-bpm-quarkus-example-simple-rest-1.0.0-SNAPSHOT-runner.jar.
