Spring Dubbo 注解无效，空指针403.10 禁止访问：配置无效 

今天采用Spring注解  Dubbo(注解)的方式整合服务
消费者
@Controller public class HomeController {

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

    @Reference(version = "0.0.1")     private IDemoService demoService;

@RequestMapping(value = "/say", method = RequestMethod.GET)     @ResponseBody public String sayHello(){ demoService.sayHello();         return "1"; }

@RequestMapping(value = "/add", method = RequestMethod.GET) public void addition(){ System.out.println(demoService.addition(5, 5)); }

}
application xml:
<dubbo:application name="consumer-of-helloworld-app" /> <dubbo:registry address="zookeeper://192.168.10.150:2181" />     <dubbo:annotation package="com.demo.dubbo.controller"/>
提供者provider
import com.alibaba.dubbo.config.annotation.Service;
@Service(version = "0.0.1") public class DemoServiceImpl implements IDemoService {

@Override public void sayHello() { System.out.println("hello dubbo!"); }

@Override public int addition(int a, int b) { int result = a + b; System.out.println("addition:" + result); return result; }

}
application xml:
<dubbo:annotation package="com.winks.dubbo.demo.provider" />

其他配置都在dubbo.properties
消费者采用的是 bat启动，

消费者的 IDemoService demoService 始终是空指针。

有谁能否提供一个是dubbo注解实例，谢谢！
