无法在Spring AOP方面自动装配Spring Bean

Question

我创建了一个新的Aspect并且没有加载自动装配的bean

@Aspect
@Component
public class LoggingAspect {

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

@Autowired
private EmployeeService employeeService;

@Autowired
private EmployeeDAO  employeeDAO;

}

未加载自动装配的bean并仅显示为null。
