启动时报错： java.lang.NoClassDefFoundError: org/apache/curator/framework/CuratorFrameworkFactory 必须添加

<dependency>
                <groupId>org.apache.dubbo</groupId>
                <artifactId>dubbo-dependencies-zookeeper</artifactId>
                <version>2.7.3</version>
                <exclusions>
                    <exclusion>
                        <groupId> org.slf4j</groupId>
                        <artifactId>slf4j-log4j12</artifactId>
                    </exclusion>
                </exclusions>
                <type>pom</type>
</dependency>

才行！

我们公司使用的zookeeper版本是3.4.13

通过依赖树查看，dubbo-spring-boot-starter里并没有对zokeeper的依赖管理，所以需要额外添加，不过dubbo的注册中心一般都是zookeeper，为何不在说明文档里做个说明呢？

Sorry for confusing on the dependencies in Zookeeper, typically there's the basic guide in README.md, and more details in samples, for this case, you could check the sample about Zookeeper, please refer this declaration in pom.xml:
