[GitHub] [servicecomb-java-chassis] sunshinexp1 opened a new issue #2740: @RpcReference注解在某些场景会失效

   针对这个@RpcReference失效的bean进行debug定位，发现初始化，执行到applyBeanPostProcessorsBeforeInitialization时，对应的RpcReferenceProcessor还没有被registerBeanPostProcessors注册上，能否提高一点RpcReferenceProcessor注册的优先级，比如实现PriorityOrdered接口，确保RpcReferenceProcessor更早一点注册，避免时序问题导致部分@RpcReference失效。

   > 能提供下具体的写法代码吗？
   
   Demo代码已经提供，可以看看是否有问题。

   我提供一个Demo吧，三个类：
   接口类：
   `public interface DemoInterface {
       void test();
   }
   `
   接口实现类：
   `@Service
   public class DemoInterfaceImpl implements DemoInterface {
       @RpcReference(microserviceName = "DemoService", schemaId = "demo-api")
       private IDemoService demoService;
       
       @Override
       public void test() {
           System.out.println("test");
       }
   }`
   
   DemoBean类实现FactoryBean，并且通过构造函数注入上述的DemoInterfaceImpl 
   `@Service
   public class DemoBean implements FactoryBean<String> {
       @Setter
       private DemoInterface demoInterface;
       
       @Autowired
       public DemoBean(DemoInterface demoInterface) {
           this.demoInterface = demoInterface;
       }
       
       @Override
       public String getObject() {
           return "demoBean";
       }
   
       @Override
       public Class<?> getObjectType() {
           return String.class;
       }
   
       @Override
       public boolean isSingleton() {
           return true;
       }
   }`
   
   最后出现的问题就是接口实现类DemoInterfaceImpl里的@RpcReference注解不生效
