发现一个很奇怪的问题，dubbo部署到k8s后给pod创建service提示Failed to bind properties under 'dubbo.providers.port' to org.apache.dubbo.config.ProviderConfig:

我用的dubbo3.0.5，使用的springboot和dubbo-spring-boot-starter搭建的dubbo服务，我打包成镜像，放到k8s中运行正常，当我给这个pod创建service后，重启一下pod就提示： Exception encountered during context initialization - cancelling refresh attempt: org.springframework.boot.context.properties.ConfigurationPropertiesBindException: Error creating bean with name 'dubbo-org.apache.dubbo.spring.boot.autoconfigure.DubboConfigurationProperties': Could not bind properties to 'DubboConfigurationProperties' : prefix=dubbo, ignoreInvalidFields=false, ignoreUnknownFields=true; nested exception is...

多个nacos注册中心，通知模块单例导致全部通知的问题

1

dubbo3.0.9，目前我看了代码感觉这个问题无解，必须改nacos的代码了 nacos多注册中心，实例发现，两遍都注册，一遍改变通知过来，两个ServiceInstancesChangedListener都会触发（因为key和group相同），NamingEvent也没有足够信息过滤掉错误的通知，导致后续处理出错 1. 条件： （1）只用实例发现 （2）配置2个nacos的注册中心 （3）服务自省用remote模式（可以明确看到两个revision不同） （4）接口A使用global导出，接口B使用nacos-registry导出，这样revision就不同了 dubbo.application.register-mode=instance dubbo.application.service-discovery.migration=FORCE_APPLICATION dubbo.registries.nacos-registry.id=nacos-registry dubbo.registries.nacos-registry.address=nacos://main-a-nacos.blurams.vip:8848 dubbo.registries.nacos-registry.use-as-metadata-center=true dubbo.registries.nacos-registry.use-as-config-center=false dubbo.registries.global.id=global dubbo.registries.global.address=nacos://global-nacos.blurams.vip:8848 dubbo.registries.global.use-as-metadata-center=true dubbo.registries.global.use-as-config-center=false dubbo.application.metadata-type=remote 2. 观察：两个注册中心都存在utopia-channel-server，他们的revision是不同的，应该计算的时候带注册中心的 3. 结果：这个时候已经满足触发的条件了，比如global-nacos.blurams.vip:8848 utopia-channel-server变更通知过来，那么 两个ServiceInstancesChangedListener都会被触发，因为key和group都是一样的 然后后续main-a-nacos.blurams.vip:8848这个ServiceInstancesChangedListener就报错了（一直死循环查地址，因为revision查不到信息） @AlbumenJ 感觉无解，数据不足，过滤不掉 我打算修改注册中心代码，目前配置group是无效的，加上dubbo.registries.global.group=public-global 这样强制group不同
