使用 curator 结合zookeeper  发现报错

使用环境：xml

	        <dependency>
			<groupId>org.apache.zookeeper</groupId>
			<artifactId>zookeeper</artifactId>
			<version>3.5.7</version>
		</dependency>
<dependency>
    <groupId>org.apache.curator</groupId>
    <artifactId>curator-recipes</artifactId>
    <version>4.0.0</version>
</dependency>

控制台信息：

log4j:WARN No appenders could be found for logger (org.apache.zookeeper.ZooKeeper).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

这个是因为 curator 版本与zookeeper 兼容问题,将curator 版本降低 再进行尝试

测试通过版本 2.13.0
