我有一个 maven+spring+gwt 项目,我想在其中使用请求工厂。我只是不知道为什么我会得到这个例外。

请求工厂:

   public interface StarRequestFactory extends RequestFactory {

@Service(value = RaduService.class, locator = GWTServiceLocator.class)
public interface RaduRequestContext extends RequestContext {
       Request<Void> save( );
    }

RaduRequestContext raduRequestcontext();
}

服务 :

public class RaduService {

  public void save(){
    System.out.println("You have saved.");
  }

} 

定位器:

public class GWTServiceLocator implements ServiceLocator,
    ApplicationContextAware {
  private ApplicationContext context;

  @Override
  public Object getInstance(Class<?> clazz) {
    return context.getBean(clazz);
  }

  @Override
  public void setApplicationContext(ApplicationContext context)
        throws BeansException {
    this.context = context;
  }

}

在我的入口点类中,我提出了请求:

requestFactory.raduRequestcontext().save().fire(new Receiver<Void>() {

        @Override
        public void onSuccess(Void response) {
            System.out.println("Success");

        }
    });

在此请求中,我收到以下错误:

有谁知道这是怎么回事?

如果需要,我可以发布 pom。

似乎是一个弹簧错误:

您是否在 ApplicationContext.xml 文件中注释或将RaduService@Service定义为 bean?
