Spring Boot以编程方式设置配置文件

我也遇到了同样的问题，经过半天的努力，我最终遇到了这个问题：

    @SpringBootApplication    public class MyApplication extends SpringBootServletInitializer {        public static void main(String[] args) { System.setProperty(AbstractEnvironment.ACTIVE_PROFILES_PROPERTY_NAME, "dev"); SpringApplication.run(MyApplication.class, args);        }        @Override        public void onStartup(ServletContext servletContext) throws ServletException { System.setProperty(AbstractEnvironment.ACTIVE_PROFILES_PROPERTY_NAME, "dev");  super.onStartup(servletContext);        }    }
