   一般来说，当存在某个type的多个候选bean时，可以通过`@Qualifier` 来指定注入的beanName， `@DubboReference`注解处理时默认以fieldName作为beanName。
   
   消费者的JavaConfig代码如下：
   
   ```java
   @Configuration
   public class JavaConfigDubbo {
       @DubboReference(group = "IServer1_A")
       private IService1 iService1;
   
       @DubboReference(group = "IServer1_B")
       private IService1 iService2;
   }
   ```
   
   消费者的Controller代码如下：
   
   ```java
   @RestController
   public class TestCcontroller {
       @Qualifier("iService1")
       @Autowired
       private IService1 service1_1;
   
       @Qualifier("iService2")
       @Autowired
       private IService1 service1_2;
   
   }
   ```
