配置中心的作用就不多说了，自行百度，总体来说就是从安全性，便捷性，统一管理来说，反正有点很多，今天来介绍一下具体的使用。配置中心可以加载本地远程两种。只需要修改一下配置方式就行了。

1，先在github上创建一个远程仓库。

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjc2UwNVprRlFSWVJuNUdWaHhHbm5Od2NtaWJPaWFsU29EeFNIQXRSN3lXU1RPTEE5WjlMaWNoUk5pYXcvNjQwP3d4X2ZtdD1wbmc][]

2，创建配置中心项目。new-->file-->moudle-->spring initializr，下一步后输入项目的信息。

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjc1VIemRpYUhENHlNM1VhVG5ETERXdDhpY1dIeWg0Z0ZTdmRMMGNiTW91U2liRlVWZ0pPYkFJQUlzUS82NDA_d3hfZm10PXBuZw][]

3，选择springcloud config项目。

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjc0t0VExQbDhNakhLUGJ2YWFLcWlibno5dlgyU2J0S2FaYzM3NDZ1aWJXVFVOZ3JEcENrOGVjSWxRLzY0MD93eF9mbXQ9cG5n][]

4，修改项目的pom文件。其他配置都可以从example-service中复制过来。只需要修改项目名和依赖即可。

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjczByMmx4d0t6QWdQbTY0Y2ZPeHZvdGhpYXc4QTFsQVppY1lMc3pTZ1lqVVFTaWM5ZGVWUmN2MEhDZy82NDA_d3hfZm10PXBuZw][]

5，在example项目中增加配置。

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjc1B3d2dMS2FMTEhRaWNDN3ZlSll3UWw3RXgwNlNNQXdmTTU3cjhYUVd4T3AwVUhlUldCV2hjaEEvNjQwP3d4X2ZtdD1wbmc][]

6，再把example-service中的配置文件复制过来一份。这时候要优化一下原来的项目的配置文件。所有的配置文件都修改为bootstrap.properties。bootstrap.properties先于application.properties加载.所以我们随项目打包的是bootstrap配置文件，在配置中心中配置的是application配置。config的配置文件不需要修改。因为它自己是不是用配置中心的配置的。（并不是所有的项目都需要，例如eureka server，这样配置会报错）

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjc0x0TXBRSHJPTWd0RDlqdzJYRXA0ZGp4MlZpYUtQQTVBaWFiVDlwSXdJYTZmdWQxcmc2N1NqYlFBLzY0MD93eF9mbXQ9cG5n][]

7，在创建的git项目config-server中创建一个文件夹example-web。在里面创建一个文件example-web-dev.properties。在文件里设置一个测试变量testpara=helloworld。

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjc1JZQmE4cmpwOUtqYUJjVGZSUnlhSktQbE5YTHA4Yk1YSVlOUnoyMGJOZjJaRTd5MDNUMHlady82NDA_d3hfZm10PXBuZw][]

8，修改example-config的配置文件。主要是git仓库的配置，每个人都不同。

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjc2hnTVVGdGNuUFBhUXJuVDZ1NXZtOW96UnUwNXlVaWJTYmpWYkZGTFNrZmRnWmZITHNOZ095dGcvNjQwP3d4X2ZtdD1wbmc][]

9，启动类上加上注解。

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjczNmRmo0NDl2aWNteE5uaWFnRWliQzZXNGZURXFuSkVabjlseDgwUUFCUWlick5teVBBU3VnMzI2R3cvNjQwP3d4X2ZtdD1wbmc][]

10，修改example-web的配置文件。增加配置中心的配置。

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjc3FPOXJHaWNqZThpY2lhRDdzd1ZXNVNwcHhMQ2NtYW5BVmdYRjZXdHNkWVZnOVNxWFJuTGdwOExwZy82NDA_d3hfZm10PXBuZw][]

11，修改example-web的测试controller，获取配置中心配置文件的值。

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjc3dENXE0blJTb1owQ2U3U1FPcEFRYmlhSWNXQVZobGFyNkFtOHlmRHFZSEgwMjhjOG1MUktqQ1EvNjQwP3d4X2ZtdD1wbmc][]

12，启动eureka，web，config三个项目，postman访问controller。可以读到配置文件。

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjc2dObVhuN1JEcFd0ZUdpYnRCMVFNOFQ5WlJRZnZFNEJWbldpYUs3YzhNYWptUUlaTXRhbVptODRnLzY0MD93eF9mbXQ9cG5n][]

13，配置本地的配置中心，只需要把git配置换成如下的配置即可。注意本地路径，win和linux都是正斜杠。并且要一直到配置文件的路径。

![aHR0cHM6Ly9tbWJpei5xcGljLmNuL21tYml6X3BuZy9lSDhuNHdzZVdsZE1LQkVvdWdJM0oweXN0eWdlOWtjc0REYjZEdmF3SFNDN3Z3M0lOQ0Z2dGljdHZFSmliaWFDQ0FUc0hWQVlKNWpUQ2FvSmhQRjB0Wm5pY1EvNjQwP3d4X2ZtdD1wbmc][]

到此springcloud的基本框架配置都讲写完了。以后会陆续写一下mq，aop，shiro等一些丰富完善的东西。
