[GitHub] [dubbo] guipengfei opened a new issue, #11826: @DubboReference(version="*")功能是否与官网描述一致？

guipengfei opened a new issue, #11826:
URL: https://github.com/apache/dubbo/issues/11826

   https://cn.dubbo.apache.org/zh-cn/overview/mannual/java-sdk/advanced-features-and-usage/service/multi-versions/ 根据官网的描述：
   ---------------------------------------------------------------------------------------
   老版本服务提供者配置
   <dubbo:service interface="com.foo.BarService" version="1.0.0" />
   
   新版本服务提供者配置
   <dubbo:service interface="com.foo.BarService" version="2.0.0" />
   
   消费者如果不需要区分版本，可以按照以下的方式配置
   <dubbo:reference id="barService" interface="com.foo.BarService" version="*" />
   --------------------------------------------------------------------------------------------------
   
   测试代码：
   消费者
   @DubboReference(group="dubbo", version="*", check = false)
       private HelloService helloService;
   
   2个服务提供者
   @DubboService(group="dubbo", version="v1.0.0")
   public class HelloServiceImpl implements HelloService {
    ...
   }
   
   @DubboService(group="dubbo", version="v2.0.0")
   public class HelloServiceImplV2 implements HelloService {
    ...
   }
   
   **控制台日志：**
   org.apache.dubbo.rpc.RpcException: Failed to invoke the method sayHello in the service com.shiguang.platform.provider.common.HelloService. No provider available for the service dubbo/com.shiguang.platform.provider.common.HelloService:* from registry 127.0.0.1:8848 on the consumer 192.168.0.107 using the dubbo version 3.0.8. Please check if the providers have been started and registered.
   
   dubbo 3.0.8 + Nacos 2.1.0 + SpringBoot 2.6.4
   无论是@DubboReference注解方式还是泛化调用都试了，都是No provider错误，请问不区分版本调用功能是否已支持，还是我的demo使用问题？

   在AbstractRegistry#noifty中调用了UrlUtils#isMatch，在如下进行处理

   我在我这边dubbo3.0.8+nacos2.1.2+springboot2.6.4是没有问题的，你应该检查一下你的服务是否已经注册上注册中心了，建议在你的配置上面加一下dubbo.scan.base-package。

   项目某些代码可能影响到了这块功能，请问对于version=*的处理，源码在哪个类呢
