              lower-case-service-id: true  #是将请求路径上的服务名配置为小写（因为服务注册的时候，向注册中心注册时将服务名转成大写的了

# 启动类加上@EnableDiscoveryClient注解 #

package com.bins.springboot.dubbo.getaway;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    
    @EnableDiscoveryClient
    @SpringBootApplication
    public class GetawayApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(GetawayApplication.class, args);
        }
    
    }

## 启动后可以看到 ##
