1.开启服务发现功能（@EnableDiscoveryClient）
@EnableDiscoveryClient //开启服务发现功能
@SpringBootApplication
public class ProductMainApplication {public static void main(String[] args) {SpringApplication.run(ProductMainApplication.class, args);}
}
2.测试服务发现api（DiscoveryClient）
package com.cx.product;import com.alibaba.cloud.nacos.discovery.NacosDiscoveryClient;
import jakarta.annotation.Resource;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.discovery.DiscoveryClient;import java.util.List;/*** @author Jiang* @date 2025/11/7*/
@SpringBootTest
public class DiscoverTest {@AutowiredDiscoveryClient discoveryClient;@Testpublic void discoveryClientTest(){List<String> services = discoveryClient.getServices();for (String service : services) {System.out.println("service = " + service);List<ServiceInstance> instances = discoveryClient.getInstances(service);for (ServiceInstance instance : instances) {System.out.println("instance.getHost() = " + instance.getHost());System.out.println("instance.getPort() = " + instance.getPort());}}}
}
3.测试服务发现api（NacosDiscoveryClient）
package com.cx.product;import com.alibaba.cloud.nacos.discovery.NacosDiscoveryClient;
import jakarta.annotation.Resource;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
