        <context:include-filter type="annotation" 
expression="com.alibaba.dubbo.config.annotation.Reference"/>
    </context:component-scan>
```

write service:  
```
@Service
public class ConsumerService {

    @Reference(parameters = {"k1", "v1"})
    private DemoService demoService;

    public void testReference() {
        System.out.println(demoService.sayHello("www.world"));
    }
}
```

And debug the referenceConfig, I found the parameter contain this key as 
follow:
