This sample project is used as live demo material for "Spring Boot 2.0 Web Applications". The recording of the session is available here.
To build this project, you need Java 1.8, Maven 3.5 and a bash-like shell.
Just invoke the following at the root of the project:
$ mvn clean install
To run this project, you also need a mongo server running your machine with default settings. If mongo is running somewhere else, please refer to the documentation to know more how you can configure Spring Boot to use that custom location.

Tip
|
This assumes that you are running the application on the command line. You can also very easily run this application from your IDE. |
First start the aggregator, from the root of the project:
$ cd smart-meter-aggregator $ mvn spring-boot:run
You should be able to check that the aggregator is running by issuing the following command:
$ curl http://localhost:8081/measures/firehose
If you prefer to use HTTPie you can use this command:
$ http :8081/measures/firehose --stream
Once you’ve made sure the aggregator is running, you can start the dasbhoard. From the root of the project:
$ cd smart-meter-dashboard $ mvn spring-boot:run
If you go to http://localhost:8080 you should see a list of zones. If you click on one
of them, you should see a graph updating itself every 10s
|
Tip
|
Initially the graph is empty as there is no data. Please wait a bit for the application to collect metrics from the aggregator. |
If you’ve been running this project a long time ago, the application will try to fetch the latest 40 entries which may create a huge gap. To restart from scratch you can remove the collection in MongoDB.
If the dashboard is running, stop it first and then invoke the following:
$ mongo > db.powergridsamples.drop()
