// 配置中心ConfigServer
// 1.引入ConfigServer的依賴,如果我們希望配置中心也是集羣
// 就要引入eurekaClient的依賴向我們註冊中心進行註冊
// 2.增加@EnableConfigServer註解
// 3.讀取本地的配置文件：在配置文件中配置服務要讀取配置文件的地址
// spring.cloud.config.server.native.search-locations: classpath:/config
// 4.其他服務要讀取的配置文件的命名規則是服務名.yml，
// 如果要加環境名如：服務名-dev.yml
// 5.修改配置文件厚愛別忘了重啓配置中心


// 服務想要從配置中心取配置要成爲ConfigClient
// 1.引入configClient依賴
// 2.application的配置文件要去配置中心讀取
// 我們要在bootstrap.yml中設置好要去讀取配置文件的
// 配置中心的位置spring.cloud.config.uri=http://localhost：8800

// 去配置中心讀取的文件的名稱不再是application.yml
// 而是服務名.yml，所以別忘了在bootstrap.yml設置服務名
// 要測試首先要保證註冊中心是開啓，然後開啓配置中心，最後啓動服務
// eurekaclient feign


// 創建倉庫的時候如果勾選了readMe相當於已經創建了1.0版本了
// 所以必須要先pull拉取下來再push將本地代碼進行推送
// 所以從創建一個本地倉庫到同步到github的步驟是
// 1.git init 創建本地倉庫
// 2. git add 要提交的內容
// 3.commit -m "提交信息" 將代碼提交到本地倉庫
// 4.git remote add origin git地址 將本地倉庫與gitHub上面創建的倉庫進行鏈接
// 5.git pull --rebase origin master 從連接到的gitHub倉庫中將最新版本的代碼拉取到本地倉庫
// 6.git push -u origin 分支名 將本地倉庫中的內容推送到gitHub倉庫
