Learning Git (slowly), so bear with me. Need to minimize my MVC test project.

Hi Ken,

Take a look at spring-attic/spring-framework-issues@2a8b821#L0R36

That statement prints false when I deploy your webapp. This means that the AsyncProcess bean is never actually getting processed for handling @Async requests. This could be because of the fact that you have an interface in the mix and that the annotation is only at the concrete class level, but in any case it appears to be a configuration issue.

Take a look at and play around with this simple test case that I contributed. You'll see there that executor selection does indeed work: spring-attic/spring-framework-issues@de91e04

If you're able to fix things up so that you've actually got an async proxy and it still fails to respect the #value attribute of the @Async annotation, feel free to reopen. Try to simplify the app as much as you can in the process.

Thanks

Chris,

The issue was that class that has the async method annotated as follows:

@Component("asyncProcess")
@EnableAsync(proxyTargetClass=true)
public class AsyncProcessClass{

Once this was added, the annotation worked flawlessly.

Thanks
Ken

@Ken,
Can you please explain which annotation was added and was there an interface involved?

Thanks,
Ittai

The annotation that I was missing was

@EnableAsync(proxyTargetClass=true)

I used an interface, but I put the annotation at the implementation level.
