- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.
- [ ] I have checked the [FAQ](https://github.com/apache/dubbo/blob/master/FAQ.md) of this repository and believe that this is not a duplicate.

### Environment

* Dubbo version: 2.6.0
* Operating System version: windows10
* Java version: 1.8

### Steps to reproduce this issue

When an Aop pointcut is an interface:
1. With @Reference, Aop does not work
2. Using XML with @Autowire, Aop works fine

当Aop切入点是接口时：
1. 使用@Reference，Aop不生效
2. 使用xml配合@Autowired，Aop正常工作

Pls. provide [GitHub address] to reproduce this issue.

```
package com.xxxx.service;
public interface XxxxService {
    DicResponseDTO<List<String>> getAllFormKey();
}

-------------------------

@Aspect
@Component
public class XxxAspect {
   @Around("execution(* com.xxxx.service.*.*(..))")
    public Object aroundApi(ProceedingJoinPoint pjp) throws Throwable {
    }
}

-------------------------------------

@RestController
public class TestController {

    /**
    *<dubbo:reference interface="com.xxxx.service.XxxxService" id="xxxService" check="false"
    *                     timeout="5000" retries="-1"/>
    **/
    @Autowired
    private XxxxService xxxxService;

    @Reference
    private XxxxService xxxxServiceRe;

    @RequestMapping("test")
    public void ss() {
        Object allFormKey =
                xxxxService.getAllFormKey();
    }
}
```

### Expected Result

What do you expected from the above steps？

Expectation: With @Reference, Aop works fine
期望：使用@Reference，Aop能正常工作

### Actual Result

What actually happens?

With @Reference, Aop does not work
使用@Reference，Aop不生效
