原pom.xml:
<!-- zookeeper 分布式锁 -->
<dependency>
<groupId>org.apache.curator</groupId>
<artifactId>curator-recipes</artifactId>
<version>4.0.1</version>
</dependency>
解决办法
修改pom.xml,从curator中剔除zookeeper依赖，单独引入zookeeper依赖。
<dependency>
<groupId>org.apache.curator</groupId>
<artifactId>curator-recipes</artifactId>
<version>4.0.1</version>
<exclusions>
<exclusion>
