配置文件 application.properties

# 端口号
server.port=5000

# 服务名
spring.application.name=eureka-server

# 是否注册自己
eureka.client.register-with-eureka=false
# 是否需要检索服务
eureka.client.fetch-registry=false

启动类 MainApplication

@EnableEurekaServer //  开启注册中心服务
@SpringBootApplication
public class MainApplication {

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

}

启动服务

访问 http://localhost:5000/
