Not able to Autowire Spring Bean in Spring AOP aspect

I have a new Aspect created and its not loading the autowired bean

@Aspect
@Component
public class LoggingAspect {

private static final Logger logger = LoggerFactory.getLogger(LoggingAspect.class);

@Autowired
private EmployeeService employeeService;

@Autowired
private EmployeeDAO  employeeDAO;

}

Autowired beans are not loaded and showing as null only.

spring version

    <org.springframework-version>4.0.6.RELEASE</org.springframework-version>
