二、问题描述

SpringBoot2使用Dubbo和zookeeper时报错：

Caused by: java.lang.ClassNotFoundException:
org.apache.curator.framework.CuratorFrameworkFactory

三、解决办法

看错误是缺少 curator 的jar包

  <dependency>
        <groupId>org.apache.curator</groupId>
        <artifactId>curator-framework</artifactId>
        <version>2.8.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.curator</groupId>
        <artifactId>curator-recipes</artifactId>
        <version>2.8.0</version>
    </dependency>

四、结果验证

问题解决。
