JobRunr example

This repository shows an advanced example how you can integrate JobRunr with spring.io. In this example, Jobs are created via a web frontend (the webapp module) and processed in a different JVM (the processingapp module).

An easier example using spring.io can be found here

About this project

This project exists out of 3 modules:

• core: this project contains MyService, a simple spring service with two example methods which you want to run in a backgroundserver.
• processingapp: this app is a Spring Console application and runs indefinitely. It polls for new background jobs and processes them when they arrive. It contains only a two classes:
  • the JobServerApplication which is empty 🙂
  • the JobServerConfiguration which starts the H2 Database (in server mode) and contains the database information

  the thing to note here is the application.properties where the server and the dashboard are enabled

• webapp: this is a Spring Rest Webapp that enqueues new background jobs. It contains a simple RestController called JobController which contains some methods (= endpoints) to enqueue jobs.

How to run this project:

• clone the project and open it in your favorite IDE that supports gradle
• First, run the main method from the JobServerApplication in the processingapp module and also keep it running
• Run the main method from the WebApplication in the webapp module and keep it running
• Open your favorite browser:
  • Navigate to the JobRunr dashboard located at http://localhost:8000/dashboard. This is running within the JobServerApplication.
  • To enqueue a simple job, open a new tab and go to http://localhost:8080/jobs/ and take it from there.
  • Visit the dashboard again and see the jobs being processed!
