How to force flowable engine to use my implementation

1

I want to use my company email infrastructure.So I created a class and extent MailActivityBehavior and override execute(DelegateExecution execution). How should I force the engine to use my implementation?

Thanks for your time.

@Component
public class MyMailSending implements JavaDelegate {
    @Autowired
    private MailService mailService;

    @Override
    public void execute(DelegateExecution delegateExecution) throws Exception {
        mailService.doSomething();
    }
}

<serviceTask id="serviceTask" flowable:delegateExpression="${myMailSending}"></serviceTask>

This uses a service task to deal with mail sending, instead of provided mail task.

Thank you. I prefer a general solution for different behaviors on flowable.

Hey

You need 3 things

1)Override the factory
@Service
public class XYActivitiBehaviorFactory extends DefaultActivityBehaviorFactory
{
protected MailActivityBehavior createMailActivityBehavior(String taskId, List fields)
{
List fieldDeclarations = createFieldDeclarations(fields);
return (MailActivityBehavior)ClassDelegate.defaultInstantiateDelegate(XYMailActivityBehavior.class, fieldDeclarations);
}
}

2)Extend MailActivityBehavior and add custom logic

public class XYMailActivityBehavior extends MailActivityBehavior
{

protected void addTo(Email email, String to, String tenantId)
{

.
}
}

3)Register your factory in processengineconfiguration.

@Autowired
private XYActivitiBehaviorFactory _factory;

processEngineConfiguration.setActivityBehaviorFactory(_factory);
