优雅下线服务

Eureka

修改配置文件

bootstrap.properties

#启用shutdown
endpoints.shutdown.enabled=true
#禁用登陆认证
endpoints.shutdown.sensitive=false
#启用pause
endpoints.pause.enabled=true
#禁用登陆认证
endpoints.pause.sensitive=false
endpoints.restart.enabled=true
endpoints.restart.sensitive=false
#client间隔n秒去拉取服务注册信息
eureka.client.registry-fetch-interval-seconds=5
#eureka server缓存刷新时间 ms
ribbon.ServerListRefreshInterval=5000

通过http请求停止服务

#将服务下线
http://ip:port/pause
#停止服务，等价于kill
http://ip:port/shutdown

Nacos

编写Controller，通过Nacos提供的api下线服务

import com.alibaba.cloud.nacos.NacosDiscoveryProperties;
import com.alibaba.cloud.nacos.registry.NacosRegistration;
import lombok.AllArgsConstructor;
import lombok.SneakyThrows;
import lombok.extern.slf4j.Slf4j;
import org.springblade.core.tool.api.R;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author ruanqi
 * @date 2021/6/11 18:19
 * @see ShutdownController
 */
@RestController
@RequestMapping("/nacos/service")
@AllArgsConstructor
@Slf4j
public class ShutdownController {

	private NacosRegistration nacosRegistration;

	private NacosDiscoveryProperties nacosDiscoveryProperties;

	@SneakyThrows
	@DeleteMapping("/shutdown")
	@SuppressWarnings("all")
	public R shutdown() {
		String serviceName = nacosDiscoveryProperties.getService();
		String groupName = nacosDiscoveryProperties.getGroup();
		String clusterName = nacosDiscoveryProperties.getClusterName();
		String ip = nacosDiscoveryProperties.getIp();
		int port = nacosDiscoveryProperties.getPort();
		log.info("deregister from nacos, serviceName:{}, groupName:{}, clusterName:{}, ip:{}, port:{}", serviceName, groupName, clusterName, ip, port);
		nacosRegistration.getNacosNamingService().deregisterInstance(serviceName, groupName, ip, port, clusterName);
		return R.status(true);
	}

}

通过http请求访问该接口

curl -X DELETE http://ip:port/nacos/service/shutdown
