不用路由
啓用路由
路由訪問映射規則
代理名稱
使用代理名稱的地址，可正確獲取到數據
此時的問題：使用原名稱依然能夠獲取數據，違背單入口單出口的原理，不合理。
原真實服務名忽略
忽略單個寫具體名稱，多可能夠用"*"
設置統一公共前綴:prefix
zuul:
#ignored-services: microservicecloud-dept
prefix: /wby
ignored-services: "*" #忽略原真實單個微服務名字寫微服務名字便可，忽略多個微服務名字寫「*」

10、springCloud config分佈式配置中心
概述
分佈式系統面臨的問題
是什麼
能幹嗎
與github整合配置
SpringCloud Config服務端配置
在github上新建名爲microservicecloud-config的新的Repository
由上一步得到SSH協議的git地址
本地硬盤目錄上新建git倉庫並clone
在本地microservicecloud-config項目裏面新建一個application.yml，切記！！！以UTF-8保存！！
spring:
profiles:
active:
- dev
---
spring:
profiles: dev #開發環境
application:
name: microservicecloud-config-wby-dev
---
spring:
profiles: test #測試環境
application:
name: microservicecloud-config-wby-test
#切記保存爲UTF-8格式
將上一步的YML文件推送到github上

$ pwd ###顯示當前文件夾
