测试
不用路由
启用路由
路由访问映射规则
代理名称
使用代理名称的地址，可正确获取到数据
此时的问题：使用原名称依然能够获取数据，违背单入口单出口的原理，不合理。
原真实服务名忽略
忽略单个写具体名称，多可能够用"*"
设置统一公共前缀:prefix
zuul:
#ignored-services: microservicecloud-dept
prefix: /wby
ignored-services: "*" #忽略原真实单个微服务名字写微服务名字便可，忽略多个微服务名字写“*”

10、springCloud config分布式配置中心
概述
分布式系统面临的问题
是什么
能干吗
与github整合配置
SpringCloud Config服务端配置
在github上新建名为microservicecloud-config的新的Repository
由上一步得到SSH协议的git地址
本地硬盘目录上新建git仓库并clone
在本地microservicecloud-config项目里面新建一个application.yml，切记！！！以UTF-8保存！！
spring:
profiles:
active:
- dev
---
spring:
profiles: dev #开发环境
application:
name: microservicecloud-config-wby-dev
---
spring:
profiles: test #测试环境
application:
name: microservicecloud-config-wby-test
#切记保存为UTF-8格式
将上一步的YML文件推送到github上
