Camunda task events notifier
Hello today i m gonna present you a project which help to notify your application when a task event is triggred.
How does it work:
We have a backend spring application which contain a dependancy named camunda bpm reactor
<dependency>
<groupId>org.camunda.bpm.extension.reactor</groupId>
<artifactId>camunda-bpm-reactor-spring-starter</artifactId>
<version>2.1.2</version>
</dependency>This dependancy will detect the time when a :
- service task
- script task
- user task
- a process
will start or complete.
then when detecting the event we will use a websocket to send a notification to an angular application, to show the event
The project structure:
Thoses classes will contains listener which will detect when a task start or end.
an example of implementation:
Here a class which listen to a task with type : usertask
the event to detect is : an End event
we use template.convertAndSent() to send the notification message to topic
and in frontend side we will listener to the topic to read messages.
Github repo:
- front end side : https://github.com/ghailen/camunda-Notification/tree/master/src
- backend side: https://github.com/ghailen/camunda-notification-with-camunda-bpm-reactor-websocket/tree/master
Demo:
