dubbo2.7.13升级到3.0.11版本兼容性问题启动报错 Dubbo2.7.13 Upgra

环境信息

Dubbo version: 2.7.13 升级到3.0.11 Operating System version: window Java version: 1.8

步骤重现

1、当一个应用实例的某个接口在本应用中用 @Autowired 注入过，并且在本应用其他的业务用@DubboReference 过。

2、因为历史项目原因 @Autowired定义的属性名不是很规范 spring容器是按照类型查找。这种就会出现2个type一样的bean 就报错了，此现状在2.7.13中是正常能跑的看有好的办法兼容吗

示例如下

https://github.com/apache/dubbo-samples/tree/master/1-basic/dubbo-samples-spring-boot/dubbo-samples-spring-boot-provider/src/main/java/org/apache/dubbo/springboot/demo/provider 把dubbo版本改为3.0.11 samples默认的这个版本应该也是有问题的。新增IDemoService2.java DemoService2Impl.java

IDemoService2.java 接口定义

public interface IDemoService2 { }

DemoService2Impl.java 接口实现

@DubboService public class DemoService2Impl implements IDemoService2 { @Autowired private DemoService demoService;

@DubboReference
private DemoService demoServiceRemote;
public void tet(){

}

}

Description:

Field demoService in org.apache.dubbo.springboot.demo.provider.DemoService2 required a single bean, but 2 were found: - demoServiceImpl: defined in file [D:\opensource\dubbo-samples\1-basic\dubbo-samples-spring-boot\dubbo-samples-spring-boot-provider\target\classes\org\apache\dubbo\springboot\demo\provider\DemoServiceImpl.class] - demoServiceRemote: defined in null

Action:

Consider marking one of the beans as @primary, updating the consumer to accept multiple beans, or using @qualifier to identify the bean that should be consumed
