启动

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：使用原名称依然可以获取数据，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，多可可以用"*"

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即可，忽略多个微服务名字写“*”
  routes:

十、springCloud config分布式配置中心

概述

分布式系统面临的问题

是什么

能干嘛

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

由上一步获得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

Administrator@WBY MINGW64 /e/gitRepository/microservicecloud-config (master)
$ pwd       ###显示当前文件夹
/e/gitRepository/microservicecloud-config

Administrator@WBY MINGW64 /e/gitRepository/microservicecloud-config (master)
$ git status   ###git仓库状态
On branch master

No commits yet

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        application.yml    ###红色，表示发生了彼岸花

nothing added to commit but untracked files present (use "git add" to track)

Administrator@WBY MINGW64 /e/gitRepository/microservicecloud-config (master)
$ git add .       ###提交修改和提交新文件是一样的两步，第一步是git add

Administrator@WBY MINGW64 /e/gitRepository/microservicecloud-config (master)
$ git commit -m "init file"   ###提交修改和提交新文件是一样的两步，第二步是git commit，""中的是提交的注释

成功实现了用springcloud config通过github获取配置信息

SpringCloud Config客户端配置与测试

在本地E:\gitRepository\microservicecloud-config下新建文件microservicecloud-config-client.yml
