上一篇：[SpringBoot+zk+dubbo架构实践（一）：本地部署zookeeper][SpringBoot_zk_dubbo_zookeeper]

前言

这是第二篇了，本篇我们完成两件事情。
    1、搭建SpringBoot 框架；
    2、基于spring boot框架访问zookeeper。

搭建SpringBoot框架

其实之前“IT实战联盟”已经出了该系列文章，今天我们简单搭建一下（详细的步骤可以参考[架构实战篇（一）-Spring Boot+MyBatis基础架构搭建][-Spring Boot_MyBatis]）

基于开发工具（IntelliJ IDEA），创建名为zkboot的Maven工程

备注：groupId、artifactId 根据自己需要修改

application.properties

#设置服务端口 server.port=8089
    server.context-path=/zkboot

Application 启动入口

package com.itunion.zkboot;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.web.support.SpringBootServletInitializer;
    /** * 启动入口 * @author lin * @date 2018年06月05日14:21:49 */@SpringBootApplicationpublic class Application extends SpringBootServletInitializer {    
    public static void main(String[] args) throws Exception {
            SpringApplication.run(Application.class, args);
        }
    
    }

RestZkController 获取设置的zookeeper node节点信息方法

package com.itunion.zkboot.web.controller;
    import org.apache.zookeeper.WatchedEvent;
    import org.apache.zookeeper.Watcher;
    import org.apache.zookeeper.ZooKeeper;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.RestController;/** * Created by lin on 2018年06月05日14:23:36 */ @RestControllerpublic class RestZkController {    
    @RequestMapping(value = "/zkGet",method = RequestMethod.GET)    
    public String zkGet(){
            Watcher watcher= new Watcher(){            
                public void process(WatchedEvent event) {
                    System.out.println("receive event："+event);
                }
            };
    
            String value = null;        
            try {            
                final ZooKeeper zookeeper = new ZooKeeper("127.0.0.1:2181", 999999, watcher);            
                final byte[] data = zookeeper.getData("/node_1", watcher, null);
                value = new String(data);
                zookeeper.close();
            }catch(Exception e){
                e.printStackTrace();
            }        
            return "获取 node_1 节点值为 [" + value + "]";
        }
    }

启动项目并测试

访问地址：http://127.0.0.1:8089/zkboot/zkGet 备注：大家要保证 zookeeper 服务正常启动，并且创建了node_1 节点和值，如果没有可以参考上一篇文章！

执行结果

备注

简单的SpringBoot集成zookeeper已经完成了，如果可以深入了解可以继续自行深入学习。
