java dubbo 连接 zk 报错 Session 0x0 for server 127.0.0.1/＜unresolved＞:2181, unexpected error, closing so

可能的解决方式

配置正常，zk 启动正常，但是就是连接不上
看下是否是你的项目使用 JDK 版本过高

我这里使用的是 17 ，调成 1.8 版本即可

问题概述

provider 配置如下

<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"><context:property-placeholder/><dubbo:application name="demo-provider"/><dubbo:registry address="zookeeper://127.0.0.1:2181"/><dubbo:provider token="true"/><bean id="demoService" class="com.dyinggq.dubbo3simpledemo.basic.impl.DemoServiceImpl"/><dubbo:service interface="com.dyinggq.dubbo3simpledemo.basic.api.DemoService" ref="demoService"/></beans>

报错如下图
