在Spring Cloud中，可以使用Spring Cloud Alibaba Nacos Discovery来从Nacos服务器获取所有微服务的地址。你需要在你的微服务中添加以下依赖：

<dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>

然后在application.properties或application.yml中配置Nacos服务器的地址：

spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

然后注入DiscoveryClient

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.discovery.DiscoveryClient;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;@RestController
public class ServiceController {@Autowiredprivate DiscoveryClient discoveryClient;@GetMapping("/services")public List<String> getServices() {return discoveryClient.getServices();}
}

根据服务名称获得ip跟端口

        List<ServiceInstance> instances = discoveryClient.getInstances("xxx");for (ServiceInstance instance : instances) {System.out.println(instance.getHost() + ":" + instance.getPort());}
