spring-cloud配置config server配置中心

在spring cloud项目中，都会配置一个配置中心去管理各个服务的配置文件，而往往配置文件不会放到本地配置中心，一般都会放到git上，下面配置一个服务如何从配置中心读取文件，配置中心如何从远程git读取配置文件。

--------------------

首先先创建项目，选择左侧的导航栏的**Spring Initializr**，然后默认是Default选项。

对项目信息进行编辑，填写组织名和项目名。

选择Cloud Discovery，然后右侧选择Eureka Discovery。

编辑项目名及存放路径，然后下一步就创建完项目了：

创建好的项目展示：

接下来配置文件：

往pom.xml文件添加所需jar包和配置，请大家根据版本选择(我用的是Dalston，所以parent标签里的version是1.5.x版本，spring-cloud.version是Dalston)：

            </repository>
        </repositories>
    
    </project>

然后到ConfigServerApplication文件里加入注解：

@EnableDiscoveryClient
    @EnableConfigServer

接下来在resources文件下的application.properties(我把后缀改成yml，效果相同)配置代码：

#配置端口号
    server:
      port: 7123
    spring:
      application:
    #应用名称
        name: config-server
      cloud:
        config:
          server:
            #从远程git读取配置文件
            git:
              #git仓库的虚拟地址
              uri: https://gitee.com/Zartillery/Factory.git
              #用户名(登录git的用户名)
              username: xxxxxxxxx@qq.com
              #密码(登录git的密码)
              password: xxxxxx
              #选择要查找的文件夹
              search-paths: Factory
    eureka:
      client:
    #默认路径(到注册中心)
        service-url:
          defaultZone: http://root:111111@localhost:7000/eureka/

然后将服务中心，配置中心启动，访问格式(localhost:配置中心端口号/文件名/版本号)，拿到了远程git的数据：
