@Async doesn't work on some methods in same class

Hi,
I am trying to send e-mail asynchronously but I successfully ran into trouble I have 2 methods in same class. Annotating one methods with @Async leads to running method asynchornously. Annotating second method with @Async doesn't work. This is that class simplified:

import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Service;

@Service
public class EmailService {

	public void sendEmailsFromTemplate(Collection<User> to, String templateName, String... args) {
		// load templates
		....
		// send emails
		sendEmails(to, subject, message);
	}

	public void sendEmails(Collection<User> to, String subject, String message) {
		for (User user : to) {
			sendEmail(user.getEmail(), subject, message);
		}
	}

	private void sendEmail(String to, String subject, String message) {
		// do real email sending
		...
	}

}

This works perfect:

@Async
public void sendEmailsFromTemplate(Collection<User> to, String templateName, String... args)

But annotating

@Async
public void sendEmails(Collection<User> to, String subject, String message)

doesn't work. Why it doesnt work?

I suggest the forum search and a read of chapter 7.6.1 of the reference guide.

Short answer
Spring uses proxy based AOP internal method calls don't pass through the proxy rendering your @Async (or any other AOP advice for that matter) useless.

Thanks for pointing me, now it makes sense
