# github创建仓库 #

1.  github 新建仓库 spring-cloud-config
2.  仓库内新建文件夹config，文件夹内新建文件 config-dev.yml

3.  config-dev.yml 文件内容
    
        server:
         port: 3355

# 搭建配置中心 #

1.  新建微服务模块 cloud-config-center3344
2.  pom引入依赖

                <artifactId>spring-boot-starter-actuator</artifactId>
            </dependency>
            <dependency>

                <optional>true</optional>
            </dependency>
            <dependency>

            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            </dependency>
            
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-config-server</artifactId>
            </dependency>
        </dependencies>
3.  修改创建 application.yml 文件
    
        server:
         port: 3344
        
        spring:
         application:
           name: cloud-config-center
         cloud:
           config:
             server:
               git:
                 #uri: git@github.com:EiletXie/config-repo.git #Github上的git仓库名字
                 # github仓库的地址，把地址栏复制粘贴即可
                 uri: https://github.com/OT-mt/spring-cloud-config
                 #搜索目录.这个目录指的是github上的目录
                 search-paths: /config
                 #因为github为外网访问较慢，所以设置超时时间较长
                 timeout: 15
             # 分支，对应github仓库的分支，可查看本文章第一张图片上的Branch
             label: master
        eureka:
         client:
           service-url:
             defaultZone: http://eureka7001.com:7001/eureka
4.  建立启动类
    
        @SpringBootApplication
        @EnableEurekaClient
        @EnableConfigServer
        public class Config_Main3344 { 
           public static void main(String[] args) { 
               SpringApplication.run(Config_Main3344.class,args);
           }
        }
5.  测试  
    访问 http://localhost:3344/config-dev.yml，即可查看到访问到github  
    中的文件。

# 客户端配置 #

1.  创建项目 cloud-config-client3355
2.  pom依赖  
    注意与服务端的依赖不同
    
        <dependencies>
                <dependency>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-web</artifactId>
                </dependency>
                <dependency>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-actuator</artifactId>
                </dependency>
                <dependency>
                    <groupId>org.projectlombok</groupId>
                    <artifactId>lombok</artifactId>
                    <optional>true</optional>
                </dependency>
                <dependency>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-test</artifactId>
                </dependency>
                
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
                </dependency>
                
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-starter-config</artifactId>
                </dependency>
            </dependencies>
           ```
3.  yml文件  
    此时 yml 文件名应该设为 bootstrap.yml,因为bootstrap的优先级大于application防止被 配置中心的配置所覆盖
    
        server:
          port: 3355
        
        spring:
          application:
            name: cloud-client
          cloud:
            config:
              # 分支与配置中心含义一样
              label: master
              # name与profile在下面讲解
              name: config
              profile: dev
              #对应配置中心的端口
              uri: http://localhost:3344
        
        eureka:
          client:
            service-url:
              defaultZone: http://eureka7001.com:7001/eureka
4.  SpringCloud Config HTTP服务具有以下格式的资源：
    
        /{application}/{profile}[/{label}]
        /{application}-{profile}.yml
        /{label}/{application}-{profile}.yml
        /{application}-{profile}.properties
        /{label}/{application}-{profile}.properties
    
    这代表可以用什么样的http路径来访问github中的资源。  
    上述五种格式中：
    
    1.  application 代表 config.name
    2.  label 代表 config.label
    3.  profile 代表 config.profile、
    
    由于本文中采用的是yml，所以这代表着可以用以下三个 路径访问github中的文件
    
    1.  http://localhost:3344/config/dev/master
    2.  http://localhost:3344/config-dev.yml
    3.  http://localhost:3344/master/config-dev.yml
