Async annotation in dependency jar, not starting a new thread

Question

I have a class in dependency jar which has a method annotated with Spring @Async and I expect that this method should execute asynchronously in another thread.

Using this class I create a bean in my parent project and wire it to my class which has @Service annotation. In that class I call a method which has @Async annotation, but as I said, the method does not execute in another thread.

How can I achieve this?

This is the code.

This is my interface class:

public interface RequestLoggerService {

    @Async
    void log(HttpServletRequest request, String serviceName, String requestIdentifier, String message, boolean successful);
}

This is the implementation class:

public class RequestLoggerServiceImpl implements RequestLoggerService {

    private static Logger logger = Logger.getLogger(RequestLoggerServiceImpl.class);

    private RequestLoggerDao requestLogger;

    @Override
    public void log(HttpServletRequest request, String serviceName, String requestIdentifier, String message, boolean successful) {
        logRequest(request, serviceName, request.getRequestURI().substring(request.getRequestURI().lastIndexOf("/") + 1), requestIdentifier, message, successful);
    }
}

Those two classes are packed in a jar which is as dependency used in my parent project. I use this class to create a bean in parent project:

<bean id="requestLoggerService" class="com.xyz.service.RequestLoggerServiceImpl">
    <property name="requestLogger" ref="requestLoggerDao" />
</bean>

And this bean is then auto-wired in my @Controller annotated class:

public class ActionsController {

    @Autowired 
    private RequestLoggerService requestLogger;
}

I followed @BretC instructions and found the solution. The problem was that I was instantiating the RequestLoggerService bean through XML configuration, but used annotation @EnableAsync to enable @Async annotation discovery.

This cant be done, either I need to use annotation driven bean creation, or to enable asynchronous tasks in XML configuration.
