推荐答案
Spring Boot already has support for profile based properties.
只需添加application-[profile].properties文件，然后使用spring.profiles.active属性指定要使用的配置文件.
Simply add an application-[profile].properties file and specify the profiles to use using the spring.profiles.active property.
-Dspring.profiles.active=local
这将从application.properties和application-local.properties的第一个优先属性中加载后者.
This will load the application.properties and the application-local.properties with the latter overriding properties from the first.
