SpringBoot 引用不同环境的配置文件, 放在外部的配置文件

@SpringBootApplication
public class SpringbootDemo1Application {
	
	public static void main(String[] args) throws IOException {
		SpringApplication app = new SpringApplication(SpringbootDemo1Application.class);
		Properties properties = new Properties();
		properties.load(new ClassPathResource("application.properties").getInputStream());
		properties.load(new FileInputStream(new File("/Users/xxxxx/application-"+ properties.getProperty("spring.profiles.active") +".properties")));
		app.setDefaultProperties(properties);
		app.run(args);
	}
}
