Jc826 commented on issue #288: 消费方使用拦截器,导致@Reference 注入为null
URL: https://github.com/apache/incubator-dubbo-spring-boot-project/issues/288#issuecomment-438538644
 
 
   > 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)
