发现服务器：

@SpringBootApplication
@EnableEurekaServer
public class EurekaDiscoveryApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaDiscoveryApplication.class, args);
    }

}
网关服务器：

我还尝试使用@enableurekaclient

@SpringBootApplication
@EnableDiscoveryClient
@EnableZuulProxy
public class GatewayApplication {

    public static void main(String[] args) {
        SpringApplication.run(GatewayApplication.class, args);
    }

}
将功能区特性设置为true无效

eureka.client.registerWithEureka=true

zuul.prefix=/api

zuul.routes.player-service=/player/**
zuul.routes.player-service.service-id=player-service

ribbon.eureka.enabled=false
spring.cloud.loadbalancer.ribbon.enabled=false
客户端服务器：

@SpringBootApplication
@EnableEurekaClient
public class EurekaClientPlayerApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaClientPlayerApplication.class, args);
    }
