1.前言:

1.1.以下內容是我通過閱讀官方文件,併成功實踐後的經驗總結,希望能幫助你更快地理解和使用spring Cloud. 

1.2.預設讀者已經熟練掌握Spring 全家桶,Spring Boot和註解開發.

1.3.陸續更新

2.開發環境:

2.1.開發工具:idea

2.2.開發環境:jdk1.7

2.3.Spring版本:

2.3.1.Spring Boot :1.4.0 release

2.3.2.Spring Cloud : Camden SR2

3.1.服務註冊demo:

3.1.1.建立工程模組,如圖所示

3.1.2.將官方提供的maven依賴,加入pom.

3.1.4.如圖步驟完成Service0,Service1類似

3.1.5.簡單到爆炸有沒有...........,接下來先啟動Discovery,然後啟動Service0和Service1

3.1.6.開啟瀏覽器,訪問 localhost:8080 ,8080是Discovery裡配置的埠號.一切順利的話,可以看到:

3.1.7.已經成功註冊了service0,service1兩個服務

3.2.閘道器demo: 光是註冊了服務還不行,這裡可以再配一個閘道器,讓服務呼叫有統一的入口. 

3.2.1.通過上圖配置後,首先啟動Discovery,其次的服務和閘道器啟動順序隨意.通過訪問localhost:8083/service0/service0,即可看到,gateway幫我們轉發了請求.

3.3.Ribbon負載均衡(未完待續)
