一 . 概述

dubbo官网
 zookeeper官网

二 . 环境准备

2.1 zookeeper安装与启动

点击下载

注意：zookeeper版本与spring-boot依赖包版本存在冲突问题，本教程只适用于zookeeper-3.5.5

步骤一：下载后解压文件，执行命令cd apache-zookeeper-3.5.5-bin/conf，cp zoo_sample.cfg zoo.cfg，复制一份zoo_sample.cfg命名为zoo.cfg

步骤二：启动zookeeper

# 进入bin目录
cd /Users/a10.11.5/Downloads/apache-zookeeper-3.5.5-bin/bin
# 启动
./zkServer.sh start

步骤三：查看是否启动成功

ps -ef | grep zookeeper

三 . 整合spring-boot

3.1 工程结构介绍

说明：统一由dubbo-manager-service-api提供提供公共接口,dubbo-manager-consumer-6002和dubbo-manager-provider-6001公共调用

3.2 dubbo-manager-service-api

    private Logger logger = LoggerFactory.getLogger(UserServiceImpl.class);

    @Override
    public List<User> getAll(String name) {
        logger.info("用户名" + name);
        User user = new User();
