> BCD三个类在注入依赖bean的时候，因为这三的属性名称一样且类型不一样（会走入你前面截图的逻辑里），按理注入的beanName应该分别为userInfo、userInfo#2、userInfo#3。我理解应该不会出现你所描述的 `beanDefinitionRegistry没有找到已经注册的bean`，我本地试了下没有问题，方便的话可以发一下你的demo我本地复现一下。
所以在此处
对newReferenceBeanName的要求应该是 没有被注册到 beanDefinitionRegistry中 且 别名中也没注册过当前名称，在生成新的newReferenceBeanName名称时 应该二次检查之前是否已经使用当前名称注册过，避免重复的注入多个别名

我觉得这种注入的写法是不规范的，当然dubbo 是需要解决这种情况的。[https://github.com/apache/dubbo/pull/10359](url) @xiangzz159 @chenziqiang666

这边的代码有问题，beanDefinitionRegistry没有找到已经注册的bean，所以index没有刷新，修改index为一个比较大的值后能正常启动

这个问题好像还存在，把有问题的变量名改一下就好了；
有问题写法：
@DubboReference
private ProjectService projectService;
没问题写法：
@DubboReference
private ProjectService gaeaProjectService;

我理解原因是spring在生成bean DClient的过程中，当赋值属性UserAInfo userInfo时，是根据名称userInfo查找对应的bean，而不是根据类型UserAInfo查找bean，这个是spring的流程，应该不算dubbo的bug

他截图部分的代码 会在 postProcessBeanFactory 和 postProcessMergedBeanDefinition 俩次触发执行，
第一次触发：（postProcessBeanFactory ）
A类 beanDefinitionRegistry.registerBeanDefinition("test", UserInfo的beanDefinition);
B类 beanDefinitionRegistry.registerBeanDefinition("userInfo", MessageInfo的beanDefinition);
C类 注册了别名 beanDefinitionRegistry.registerAlias("test", "userInfo#2");
D 类 beanDefinitionRegistry.registerBeanDefinition("userInfo#2", UserAInfo的beanDefinition);
第二次触发：（postProcessMergedBeanDefinition ）
A类 B类 在上图代码中会从缓存中获取到直接返回
C类传入的referenceBeanName是userInfo 在 UserInfo类型对应的缓存中是 test/userInfo#2 没有命中缓存，会走到
这部分执行时 C类获取到 newReferenceBeanName 应该是 userInfo#3 ，因为 userInfo 和 userInfo#2 被 B 和 D 注册到了beanDefinitionRegistry中 ，此时会继续注册alias beanDefinitionRegistry.registerAlias("test", "userInfo#3");
D 类 传入的referenceBeanName是userInfo 在 UserAInfo类型对应的缓存中是 userInfo#2 没有命中缓存，走到上图红框中执行
D 类获取到 newReferenceBeanName 应该是 userInfo#3 ，因为userInfo被B注册 userInfo#2 被他之前自己注册过了，之后会注册别名 userInfo#3: userInfo#2 此时因为别名 userInfo#3 被 test 注册过了 如果 allowBeanDefinitionOverriding 为false 则会抛出异常
如果允许覆盖则 别名会变成如图所示
 之后当前D类的 AnnotatedFieldElement的 injectedObject 值被设置为 userInfo#3
在D类执行属性注入时 InjectedElement.inject 从spring中获取bean对象是 beanName 是 AnnotatedFieldElement.injectedObject 的值
此时从spring 获取bean的时候
会从 别名中获取到 真的 注入容器中的那个名称 test test 是UserInfo 类型的， 而D类注入的 类型UserAInfo
如图 field 是 UserAInfo injectObject 是 UserInfo类型的 dubbo 代理类，此时类型不匹配 会抛出异常
