What you expected to happen

配置文件中可以写
xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"
或者
xmlns:dubbo="https://dubbo.apache.org/schema/dubbo"

http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd
https://dubbo.apache.org/schema/dubbo https://dubbo.apache.org/schema/dubbo/dubbo.xsd
