import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@EnableAdminServer
@SpringBootApplication(exclude = {
   
   DataSourceAutoConfiguration.class})
@EnableDiscoveryClient
public class GatewayApplication {
   
   
    public static void main(String[] args) {
   
   
        SpringApplication.run(GatewayApplication.class, args);
        System.out.println("网关服务启动成功");
    }
}

以上是从项目中摘录的，大概思路就是这样。
