frlzk opened a new issue #8777: URL: https://github.com/apache/dubbo/issues/8777
- [ ] 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: 3.0.2.1 * Operating System version: Ubuntu20 * Java version: 1.8 * nacos 2.0 ### Steps to reproduce this issue 一个接口4个实现，其中两个实现在consumer端，另两个在provider端。这4个实现属于不同的group ` //接口定义 public class Hello implements Serializable { private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } } public interface HelloService { public List<Hello> hellos(); } //使用接口的Controller @Controller public class HelloController { @DubboReference(group="*",merger="list" ) //scope="remote", HelloService service; @RequestMapping("/hellos") @ResponseBody public List<Hello> hellos() { return service.hellos(); } } //消费端接口实现 @DubboService(group="consumerHello1") public class Hello1ServiceImpl implements HelloService { public List<Hello> hellos(){ List<Hello> res=new ArrayList(); Hello hell=new Hello(); hell.setName("consumer-hello-1"); res.add(hell); return res; } } @DubboService(group="consumerHello2") public class Hello2ServiceImpl implements HelloService { public List<Hello> hellos(){ List<Hello> res=new ArrayList(); Hello hell=new Hello(); hell.setName("consumer-hello-2"); res.add(hell); return res; } } //服务端接口实现 @DubboService(group="providerHello1") public class Hello1ServiceImpl implements HelloService { public List<Hello> hellos(){ List<Hello> res=new ArrayList(); Hello hell=new Hello(); hell.setName("provider-hello-1"); res.add(hell); return res; } } @DubboService(group="providerHello2") public class Hello2ServiceImpl implements HelloService { public List<Hello> hellos(){ List<Hello> res=new ArrayList(); Hello hell=new Hello(); hell.setName("provider-hello-2"); res.add(hell); return res; } } ` ###运行结果和期望结果共7种情况，其中只有一个符合预期: 1. 不设置scope参数:@DubboReference(group="*",merger="list") 1.1 只启动consumer,调用HelloController 结果:返回一条数据 期望:返回两条数据 1.2 先启动consumer,再启动provider,调用HelloController 结果:返回一条数据 期望:返回四条数据 1.3 先启动provider,再启动consumer,调用HelloController 结果:返回一条数据 期望:返回四条数据 2. 设置scope参数:@DubboReference(group="*",merger="list",scope="remote") 2.1 只启动consumer,调用HelloController 结果:返回一条数据 期望:返回两条数据 2.2 先启动consumer,再启动provider,调用HelloController 结果:返回一条数据 期望:返回四条数据 2.3 先启动provider,再启动consumer,调用HelloController 结果:返回四条数据 期望:返回四条数据 2.3 先启动provider,再启动consumer,调用HelloController,关闭provider,再次调用HelloController 结果:org.apache.dubbo.rpc.RpcException: No provider available from registry 127.0.0.1:8848 期望:返回两条数据 -- This is an automated message from the Apache Git Service.
