4.配置ZooKeeper连接在application.yml文件中配置ZooKeeper的连接字符串。
spring:application:name: productcloud:zookeeper:connect-string: localhost:2181
server:port: 8101
5.新增Controller:
package com.example.zookeeperserver;import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;RestController
RequestMapping
public class ProductController {GetMapping(product)public String product(){return this is product;}
}package com.example.zookeeper;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.discovery.DiscoveryClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;import java.util.List;RestController
public class ServiceController {Autowiredprivate DiscoveryClient discoveryClient;/*** Description:通过注入DiscoveryClient实例来获取服务实例的信息* Author: * Date: 2024/2/7 15:46* return: java.util.Listjava.lang.String* 访问地址http://localhost:8101/services**/GetMapping(/services)public ListString getServices(){//返回所有注册到服务发现中心的服务名称return discoveryClient.getServices();}/*** Description:* Author: * Date: 2024/2/7 15:52* param serviceName:* return: java.util.Listorg.springframework.cloud.client.ServiceInstance* 访问地址http://localhost:8101/serviceInstances/product**/GetMapping(/serviceInstances/{serviceName})public ListServiceInstance getServiceInstance(PathVariable String serviceName){//getServiceInstances方法接受一个服务名称作为参数返回该服务的所有实例。//每个ServiceInstance对象包含了服务实例的详细信息如主机名、端口号等return discoveryClient.getInstances(serviceName);}}
6.启动本地的服务端 7.启动服务注册和发现在主应用类中通过EnableDiscoveryClient注解启用服务注册和发现
8.访问localhost:8101/product 完整项目代码
