4:启动类
package tigee;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@SpringBootApplication
@EnableDiscoveryClient
public class ApplicationMain {
static final Logger logger = LoggerFactory.getLogger(ApplicationMain.class);
public static void main(String[] args) {
logger.debug("服务启动..start......");
SpringApplication.run(ApplicationMain.class, args);
logger.debug("服务启动..end......");
}
}
3:启动看 注册中心
4:请求接口
http://localhost:7101/user-service/hello?name=12
5:user-service 动多个端口
再请求 localhost:7101/user-service/hello?name=12
