Difference of TaskListener and ExecutionListener in User Task

which listener I should use?

What is the difference of TaskListener and ExecutionListener in User Task,
and what is their execution sequence?

Thank you.

Camunda help with TaskListener and ExecutionListener

Hi, i am new to camunda. First i’m using spring boot starter with examples from https://github.com/camunda/camunda-bpm-examples/tree/master/spring-boot-starter. I’m kind of confused with TaskListener and ExecutionListener. I use them with spring-native event-bridge. A few questions I have a TaskListener like this: @EventListener(condition = "#event.eventName=='create'") public void onTaskCreatedEvent(TaskEvent event) { // handle immutable task event log.info("handle …

I think the important difference to remember is that the ExecutionListener is available for all elements and allows access to the DelegateExecution, while the TaskListener only applies to tasks (bpmn and cmmn) and gives you access to the DelegateTask.

The DelegateTask is important for all task-lifecycle operations, like setting due date, assigning candidate groups, … you just cannot do this with the DelegateExecution.

So in general, we use ExecutionListeners on events and gateways, JavaDelegates on ServiceTasks and TaskListeners on UserTasks.
