SpringBoot ZooKeeper集成
1.下载ZooKeeper
官网：https://zookeeper.apache.org/
下载链接：https://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.6.1/apache-zookeeper-3.6.1-bin.tar.gz
2.解压配置
解压后目录为：
将conf目录下的zoo_sample.cfg文件，复制一份，重命名为zoo.cfg，
修改zoo.cfg配置文件，将dataDir=/tmp/zookeeper修改成zookeeper安装目录所在的data文件夹（我的目录：dataDir=E:\apache-zookeeper-3.6.1-bin\apache-zookeeper-3.6.1-bin\data）这里可手动添加，也可启动自动生成，再添加一条添加数据日志的配置，如下图：
3.启动zookeeper
启动后如下图：

4 创建项目
进入https://start.spring.io/
具体可查看：https://blog.csdn.net/qq_45556336/article/details/106120133
把项目下载下来导入即可(IDEA此方法应该不行)。
修改项目名再次创建consumer 下载，导入如下图。
pom文件如下：

5.编写代码
zk-producer项目：
在application.property添加如下配置：
server.port=8000
spring.application.name=zktest
spring.cloud.zookeeper.connect-string=127.0.0.1:2181
创建控制类
package com.qifan.zkproducer.controller;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/pro")
@EnableDiscoveryClient
public class ProController {
@RequestMapping("/test")
public String test() {
return "hello-zookepper!";
}
}
zk-consumer项目：
在application.property添加如下配置：
server.port=8001
spring.application.name=zktest2
spring.cloud.zookeeper.connect-string=127.0.0.1:2181
编写启动类
添加@EnableFeignClients，这里我使用RestTemp进行调用(也可使用Feign)，创建RestTemplate实例
@LoadBalanced一定要加
package com.qifan.zkconsumer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.cloud.openfeign.EnableFeignClients;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;
@SpringBootApplication
@EnableFeignClients
public class ZkConsumerApplication {
@Bean
@LoadBalanced
public RestTemplate restTemplate() {
return new RestTemplate();
}
public static void main(String[] args) {
SpringApplication.run(ZkConsumerApplication.class, args);
}
}
创建控制类
注入RestTemplate实例
package com.qifan.zkconsumer.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
@RestController
@RequestMapping("con")
@EnableDiscoveryClient
public class ConController {
@Autowired
private RestTemplate restTemplate;
@RequestMapping("test")
public String test() {
String s = restTemplate.getForObject("http://zktest/pro/test", String.class);
return s;
}
}
6.启动项目
分别运行启动类
运行zkClient.cmd可以查看项目服务
项目启动完成
7.浏览器访问
可以看到我们访问的8001端口调用到8000端口的test方法。
