spring:
  profiles:

# 此处dev可以换成sit，uat，pro
# application.yml也可以换成application.properties文件，则是 spring.profiles.active=dev

//在启动类中，将原本的 
SpringApplication.run(Application.class, args);
 
//替换成如下
SpringApplicationBuilder builder=new SpringApplicationBuilder(Application.class);
builder.application().setAdditionalProfiles("dev");
builder.run(args);
