Do some initialize job after user start process use reactor

I did a lot of search and find reactor is helpful for my purpose, but can’t get process start event.

@CamundaSelector(type = “userTask”, event = ExecutionListener.EVENTNAME_START)
public class MyExecutionListener implements ExecutionListener {
private final static Logger LOGGER = Logger.getLogger(MyExecutionListener.class.getName());

public void notify(DelegateExecution execution) throws Exception {
String activityName = execution.getCurrentActivityName();"activityName: " + activityName);

You want reator to inform you when you pass a startevent? Then why do you register on type “userTask”?

Then what @CamundaSelector type should i set ?

I think it should be “startEvent”
