[GitHub] [dubbo] peachyy opened a new issue, #11080: dubbo2.7.13升级到3.0.11版本 兼容性问题启动报错

peachyy opened a new issue, #11080:
URL: https://github.com/apache/dubbo/issues/11080

   
   ### Environment
   
   * Dubbo version: 2.7.13 升级到3.0.11
   * Operating System version: window
   * Java version: 1.8
   
   ### Steps to reproduce this issue 重现此问题的步骤
   
   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
   
   示例如下 
   https://github.com/apache/dubbo-samples.git/1-basic/dubbo-samples-spring-boot/dubbo-samples-spring-boot-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
   
   ``` java  
    public interface IDemoService2 {
   }
   ```
   
   DemoService2Impl.java 接口实现
   
   ``` java 
   @DubboService
   public class DemoService2Impl implements IDemoService2 {
       @Autowired
       private DemoService demoService;
   
       @DubboReference
       private DemoService demoServiceRemote;
       public void tet(){
   
       }
   }
   ```
   
   启动异常

   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

   这个是由于 Dubbo 3 中 spring 把所有的 reference bean 都注册到 spring 去了。如果没有指定一个 bean 去 autowire 的话也没法决策是使用本地发布的（service bean）还是订阅的（甚至可能有多个，配置不一样）。
   所以最好是在升级的时候把有问题的都处理掉，提前排除风险。

   是呀 之前项目中都是用的自定义的代码生成器 本地服务全部都是用的spring autowire 。属性名却不是规范的 (ಥ﹏ಥ)
