3 - Dubbo x Spring Boot 开发微服务应用

https://cn.dubbo.apache.org/zh-cn/overview/mannual/java-sdk/quick-start/spring-boot/

文档中说jdk8及以上版本都可以。实际情况下，必须得是jdk8才能运行。

jdk11和jdk17都会抱错：
Unable to canonicalize address 127.0.0.1/:2181 because it's not resolvable

建议修改下文档说明，或者优化demo程序，以支持更高版本jdk

Start with the linked Spring Boot quick-start page and run its example under JDK 8, 11, and 17 to reproduce the reported ZooKeeper address error. Then determine whether the JDK support statement or the demo needs changing; done means the documentation and supported-version behavior agree.
