**一 代码位置**

[https://github.com/cakin24/spring-cloud-code/tree/master/ch][https_github.com_cakin24_spring-cloud-code_tree_master_ch]12-1

**二 测试**

1 启动config-server-placeholders

2 启动config-client-placeholders

3 浏览器输入： [http://localhost:9100/getConfigInfo][http_localhost_9100_getConfigInfo]

匹配到的配置如下：

这里的1和3来自客户端的spring.cloud.name配置。

**三 说明**

服务端配置：

spring:
      cloud:
        config:
          server:
            git:
              uri: https://gitee.com/zhongzunfa/{application}
              #username:
              #password:
              search-paths: SC-BOOK-CONFIG
      application:
        name: ch12-1-config-server-placeholders

客户端配置

spring:
        cloud:
            config:
                label: master
                uri: http://localhost:9090
                name: spring-cloud-config
                profile: dev

\{application\}代表了应用名，当客户端应用向Config Server发起获取配置请求时，Config Server会根据客户端的spring.cloud.name信息来填充\{application\}占位符以定位配置资源的存储位置，从而实现根据微服务应用的属性动态获取不同位置的配置。
