SpringBoot多环境配置

可以从以下位置加载配置文件，优先级由高到低

Config locations are searched in reverse order. By default, the configured locations are classpath:/,classpath:/config/,file:./,file:./config/*/,file:./config/. The resulting search order is the following:

1. file:./config/
2. file:./config/*/
3. file:./
4. classpath:/config/
5. classpath:/
