**一 代码位置**

[https://github.com/cakin24/spring-cloud-code/tree/master/ch18-1][https_github.com_cakin24_spring-cloud-code_tree_master_ch18-1]

**二 测试**

1 启动ch18-1-eureka

2 启动ch18-1-consumer

3 启动ch18-1-provider

4 ch18-1-gateway配置如下，然后启动

spring:
      application:
        name: sc-gateway-server
      cloud:
        gateway:
          discovery:
            locator:
              enabled: true
              # 开启小写的serviceId进行基于服务的路由的转发
              lowerCaseServiceId: true
    
    
    server:
      port: 9000  #网关服务监听 9000 端口
    eureka:
      client:
        service-url: #指定注册中心的地址，以便使用服务发现功能
          defaultZone: http://localhost:8761/eureka/
    
    
    logging:
      level: #调整相关包的 log 级别，以便排查问题
        org.springframework.cloud.gateway: debug

5 浏览器输入： [http://localhost:9000/sc-consumer/hello/zhangsan][http_localhost_9000_sc-consumer_hello_zhangsan]
