[GitHub] [incubator-dubbo-spring-boot-project] ZuRun opened issue #288: @Reference 注入为null

["ZuRun (GitHub)" <gi...@apache.org>]

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

}
```
目前只发现这种情况有问题,一下情况都正常
1. 使用`Constants.PROVIDER`的拦截器可以正常使用.
2. 消费方不使用此拦截器的时候,`@Reference`注解可以正常注入
3. 提供方拦截器是正常使用的
