IssueEvent EventListener method called twice in plugin

Hello,

I am currently trying to get into jira plugin development.

My issue is that my EventListener for IssueEvent gets called twice with the same data, which makes things complicated for me.

The method onIssueEvent gets called twice:

@ExportAsService
@Component
@Named("IssueModificationListener")
public class IssueModificationListener implements DisposableBean, InitializingBean, LifecycleAware {

    @ComponentImport
    private final ApplicationProperties applicationProperties;
    @ComponentImport
    private final EventPublisher eventPublisher;
    @ComponentImport
    private final LifecycleManager lifecycleManager;

    @Inject
    public IssueModificationListener(ApplicationProperties applicationProperties, EventPublisher eventPublisher, LifecycleManager lifecycleManager) {
        this.applicationProperties = applicationProperties;
        this.eventPublisher = eventPublisher;
        this.lifecycleManager = lifecycleManager;
        eventPublisher.register(this);
    }

    public void destroy() throws Exception {

    }

    public void afterPropertiesSet() throws Exception {
        eventPublisher.register(this);
    }

    public void onStart() {

    }

    @EventListener
    public void onIssueEvent(IssueEvent issueEvent) {
        Long eventTypeId = issueEvent.getEventTypeId();
        Issue issue = issueEvent.getIssue();
        if (eventTypeId.equals(EventType.ISSUE_COMMENTED_ID)) {
            System.out.println("Issue commented on");
        } else if (eventTypeId.equals(EventType.ISSUE_COMMENT_EDITED_ID)) {
            System.out.println("Comment edited");
        } else if (eventTypeId.equals(EventType.ISSUE_COMMENT_DELETED_ID)) {
            System.out.println("Comment deleted");
        }
    }
}

Resulting in the following output:

[INFO] [talledLocalContainer] Comment deleted
[INFO] [talledLocalContainer] Comment deleted

Is there anything I can do to prevent this from happening?

The used jira version is 6.4.12

 

Thanks in advance!

Actually, I just see that eventPublisher.register(this) gets called twice, once in the constructor and in afterPropertiesSet... That might explain things.

try to remove these annotations 

@ExportAsService
@Component
@Named("IssueModificationListener")

 because it will register the class into the container several times and the method annotated with @EventListener will be fired twice or more
