在使用Spring Cloud Zookeeper进行服务注册时遇到KeeperException$UnimplementedException错误，原因是Pom.xml中默认依赖的Zookeeper版本与实际运行环境中的Zookeeper版本不匹配。解决方案是排除默认依赖的Zookeeper版本，手动指定与当前环境匹配的Zookeeper版本（例如3.4.9）。

问题描述：

问题排查：

Pom.xml默认引入的依赖版本，与实际使用的zookeeper版本冲突

<!-- springboot 整合zookeeper客户端-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
</dependency>

解决方案：

排除依赖自带的zookeeper版本，添加自己使用的zookeeper版本（我的是3.4.9），pom.xml修改如下

<!-- springboot 整合zookeeper客户端-->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
    <!-- 排出自带的3.5.3版本-->
    <exclusions>
        <exclusion>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
        </exclusion>
    </exclusions>
</dependency>
<!-- 添加我所使用的zookeeper版本：3.4.9-->
<dependency>
    <groupId>org.apache.zookeeper</groupId>
    <artifactId>zookeeper</artifactId>
    <version>3.4.9</version>
</dependency>
