SpringBoot + Zookeeper的服务注册与发现

1.SpringBoot与Zookeeper的通信问题

    注意关闭zookeeper服务的防火墙

      临时关闭

systemctl stop firewalld

     禁止开机启动

systemctl disable firewalld

2.包冲突问题

    最常见的问题是slf4j与log4j的包冲突

    解决方案：在zookeeper中去除对slf4j的依赖

<dependency>
    <groupId>org.apache.zookeeper</groupId>
    <artifactId>zookeeper</artifactId>
    <version>3.4.10</version>
