基于文件系统的Spring Cloud 配置服务器

如果想根据不同环境,使用不同的启动命令,读取不同的配置去启动项目,可以将不同环境信息写入文件中,在启动项目的时候,指定环境就可以了.

创建一个SpringCloud工程.

项目路径:

config下的licensingservice是不同环境的配置文件.

在application.yml中配置项目扫描的配置文件路径:

server:
           port: 8888
        spring:
          profiles:
            active: native
          cloud:
             config:
               server:
                   native:
                       searchLocations: classpath:config/,classpath:config/licensingservice

在licensingservice中的配置文件命名规则是:应用程序名称-环境名称.yml

配置好后,启动程序,就能够得到相应环境的配置信息.

http://localhost:8888/licensingservice/dev2

是json字符串.
