zuul starter:

/**

 * zuul application the port is 7001
 * @author Jackie L

 */
@SpringBootApplication
@EnableZuulProxy
@EnableDiscoveryClient
public class Zuul7001Boot {

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(Zuul7001Boot.class) ;
        app.run(args) ;
    }
}

consumer starter:

@SpringBootApplication
@EnableEurekaClient
@EnableDiscoveryClient
public class Consumer9001 {

    public static void main (String[] args)
    {
        var app = new SpringApplication(Consumer9001.class) ;
        app.run(args) ;
    }
}

I'm sure my service is properly registered with the Eureka server. Can you give us some ideas, thanks a lot!!!!!

I find that source code. The 'Server' is null ? What causes this?
