> dubbo消费方,使用了拦截器,且group为`Constants.CONSUMER`时,会导致`@Reference`注解注入失败.此时消费方调用提供方时,demoService为null,抛出空指针异常.

> ```java
> @Activate(group = {Constants.CONSUMER})
> public class DubboFilter implements Filter{

>
> ```java
> @Reference(version = "${dubbo.service.version}")
> private DemoService demoService;

> 目前只发现这种情况有问题

> 1. 先启动的provider,然后启动的consumer
> 2. 使用了拦截器才会有问题
> 3. 使用`Constants.PROVIDER`的拦截器可以正常使用.
> 4. 消费方不使用此拦截器的时候,`@Reference`注解可以正常注入
> 5. 提供方拦截器是正常使用的
@Reference(check=false)
